    Description: Abstract
    Description: This data set is the part 8 of a series reporting chemical data for accessory minerals from felsic igneous rocks. Compositional data were acquired by electron-probe microanalysis (EPMA) between about 1995 and 2005 on surface rocks and borehole samples. This data set assembles the results of EPMA of fluorapatite from felsic rocks representing three groups of granites in the Erzgebirge−Vogtland metallogenic province of Germany emplaced in the late Carboniferous: F-poor biotite granites, F-poor two-mica granites, and P-F-rich Li-mica granite. In these rocks, fluorapatite is typically omnipresent. It has to be noted that apatite has not yet been in the focus of mineralogical studies of the granites in this province and a comprehensive survey of its compositional signature and variability in space and time is still pending. However, the data listed in this data set provide a valuable glimpse into the similarities and differences in apatite chemistry between geochemically distinct felsic rocks, and into the evolution in composition from early to late crystallizing apatite populations. The data underpin that apatite is a sensitive monitor of the compositional properties of the media (melts and fluids) from which it was deposited or with which it interacted. Apatite from the studied rocks is basically fluorapatite with little or no Cl and OH detected respectively inferred. Elemental variations are observed at various scales, i.e., between granite groups, subsequently crystallized sub-intrusion within composite massifs, grains present in a single thin section, or between the center and the rim of a particular grain. These variations in particular refer to the following elements: Mn, Fe, Na, and the rare-earth elements (REE). For example, measured Mn concentrations range from 0.15 to 8.8 wt% MnO. The data set contains the complete pile of electron-microprobe analyses for fluorapatite (APAT-ERZ-2020). The data are presented as Excel (xlsx) and tab-delimited text (txt) formats. The content of the tables and further information on the granites and regional geology are provided in the data description file.

    Description: Mg/Ca anlaysis of foraminiferal calcite shells. Foraminifera obtained from sediments (benthic, Uvigerina spp.; sediment from ODP Site 1015, California Margin) and from plankton tows (planktonic, Orbulina universa, plankton tow specimens were collected near Green Island, Taiwan in May 2019 using a 1 m plankton net Sea-Gear, 150 µm mesh, 0-50 m depth), were analyzed. Mg/Ca were obtained applying Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and wavelength-dispersive X-Ray Spectroscopy by electron probe microanalyzer (EPMA). The goal is to assess the use of EPMA as an alternative technique for Mg/Ca analyses of foraminiferal calcite shells.

    Description: Abstract
    Description: The European-Mediterranean Seismological Centre (EMSC) is a non-profit scientific organization aiming at establishing and operating a rapid earthquake detection system globally and in particular in the European and Mediterranean regions as well as facilitating exchange between seismological institutes. The EMSC has been a pioneer in citizen seismology by collecting in-situ information on the earthquake impact directly from the witnesses. The EMSC has been collecting citizen intensity felt reports at a global scale for many years via two channels: its websites and its “LastQuake” smartphone application. These felt reports are collected through a set of 12 cartoons representing the 12 levels of the European Macroseismic Scale (Grünthal, 1998). They provide rapid information on how the earthquake’s impact is felt by the local population. The EMSC felt reports were shown to be consistent with the USGS Did You Feel It? (Wald et al., 2011) responses and with manually derived macroseismic datasets (Bossu et al., 2017). Such felt reports are provided for a set of 36 earthquakes, each tagged with a unique ID number. They are only considered for intensity values of up to 10, since higher values are unrealistic. Additionally, an interactive map of the aftershocks distribution is provided for each earthquake. These aftershocks are selected from the EMSC catalogue in the 14 days after the event and within 500km of the epicentre location. On each map, the beachball representing the two nodal planes as given by the Global Centroid Moment Tensor catalogue (Dziewonski et al., 1981; Ekstrom et al., 2012) is displayed at the epicentre location. For each event (identified by unique id number), the first line indicates catalogue information on the earthquake (event_id, region, origin_time (UTC), latitude, longitude, depth, magnitude, strike angle from GCMT) Each following line is a felt report gathered by the EMSC including, the longitude, latitude, reported intensity and report time.

    Description: The data set comprises new thermochronologic data along the TRANSALP geophysical transect in the Eastern Alps, i.e. (i) apatite and (ii) zircon (U-Th)/He measurements (Tables S1, S2 and S3), and (iii) HeFTy inverse thermal time-temperature-path models ('HeFTy_Models.zip') including a table of parameters used (Table S4). Individual model files can be opened using the HeFTy software (Ketcham et al., 2007).
    Description: Methods
    Description: Sampling method Bedrock samples were taken along the TRANSALP geophysical transect (e.g., Lüschen et al., 2004; 2006) with the main purpose of relating new (and existing) thermochronological data to previously identified mantle geometries and to gain orogen-scale insights into the evolution of the eastern European Alps since initialization of collision in the Eocene/Oligocene. Apatite and zircon (U-Th)/He analyses were the method of choice for two reasons: (i) these systems are considered most suitable to detect periods and locations of increased exhumation that are related to the Neogene evolution of the European Alps including changes in mantle geometries, and (ii) these systems systematically complement existing thermochronology data along the transect, which are predominantly comprised of fission-track data. Detailed analytical procedure is described in the dateset description file ("2020-48_Eizenhöfer-et-al_Data Description.pdf").

    Description: Abstract
    Description: The dataset is supplementary material to the Solid Earth research article of Leonhardt et al. (2021). The dataset is a high-resolution catalog of seismicity framing the stimulation campaign of a 6.1 km deep Enhanced Geothermal System (EGS) in Helsinki suburban area, Finland. Within the St1 Deep Heat project, a total of 18,160 m3 of fresh water was injected into crystalline rocks during 49 days in summer 2018. The seismicity was monitored by a 12-level seismometer array at 〉2km depth and a seismic network of near-surface borehole sensors surrounding the EGS site. We expanded and refined the original catalog of Kwiatek et al. (2019) including detected seismic events and earthquakes that occurred two month after the end of injection and determining new locations and relocations on the basis of a new velocity model derived from a post-stimulation vertical seismic profiling campaign. A detailed description of the catalog reprocessing as well as a description of basic statistical and spatio-temporal properties of the catalog can be find in the data description file. Definition of columns in the data table (also in the header of the data): event ID, event class, datenumber [integer part = day since year 0], year, month, day, hour, minute, seconds, local magnitude MLHEL, moment magnitude MW, absolute location in local cartesian coordinates [easting (m), northing (m), altitude (m)], relocated location in local cartesian coordinates [easting (m), northing (m), altitude (m)], fault plane solutions of estimated focal mechnisms [strike (°), dip (°), rake(°)] and root mean square fault plane uncertainty of estimated focal mechanisms.

    Description: Abstract
    Description: In geosciences 3D geomechanical-numerical models are used to estimate the in-situ stress state. In such a model each geological unit is populated with the rock properties Young’s module, Poisson ratio, and density. Usually, each unit is assigned a single set of homogene-ous properties. However, variable rock properties are observed and expected within the same geological unit. Even within small volumes large variabilities may occur. The Python script HIPSTER (Homogeneous to Inhomogeneous rock Properties for Stress TEnsor Research) provides an algorithm to include inhomogeneities in geomechanical-numerical models that use the solver Abaqus® or the MOOSE Framework. The user specifies the mean values for the rock properties Young's module, Poisson ratio and density, and their variability for each geological unit. The variability of the material properties is indi-vidually defined for each of the three rock properties in each geological layer. For each unit or unit subset HIPSTER generates a normal or uniform distribution for each rock property. From these distributions for each single element or subset of elements HIPSTER draws indi-vidual rock properties and writes them to a separate material file. This file defines differ-ent material properties for each element. The file is included in the geomechanical-numerical analysis solver deck and the numerical model is solved as usual. HIPSTER is fully documented in the associated data report (Ziegler, 2021, https://doi.org/10.48440/wsm.2021.001) and can also be accessed at Github (http://github.com/MorZieg/hipster).

    Description: An existing ice core sulfate dataset was processed to identify the largest volcanic eruption peaks of the last 203 kyr. The dataset used consisted of high resolution sulfate data (previously archived at https://www.ncdc.noaa.gov/paleo-search/study/31332), analysed by fast ion chromatography, from the EPICA Dome C ice core. To process the data, a background was removed, and fluxes of sulfate deposited were calculated for every peak above background, using a consistent method that corrects for ice accumulation rate and thinning. A threshold flux of 20 mg m⁻² yr⁻¹ has been used to ensure that only peaks of definite volcanic origin are listed. This dataset lists the depths, ages (AICC2012 age model) and fluxes of each peak with a flux 〉 20 mg m⁻² yr⁻¹.

    Description: In order to improve the poor Gondwana paleomagnetic database for Devonian times, detailed paleomagnetic analyses were performed on red chert-like rocks and partly silicified paleosols within the Lower Devonian Ikniouen level of the Tadrart Formation. Silicification, limited to this level that is only a few meters thick, was probably due to tropical warm climatic conditions during and shortly after the rock deposition. In two sections 40 km away each other, paleomagnetic data point out a high temperature Characteristic Remanent Magnetization (ChRM) with a very well-defined mean direction and a positive reversal test. Rockmagnetism data evidence minerals of the hematite family, but the presence of a minor amount of other mineral phases remains possible. These paleomagnetic results could have major geodynamical implications for the Gondwana supercontinent. In fact, ChRM acquired in this level during or shortly after deposition should imply a very unexpected fast latitudinal continental drift of the Gondwana during the Lower Devonian. That should correspond, for the APWP, to a large loop with a reversal of the drift direction from a much more southern extreme location than previously assumed. A "more realistic" interpretation should be related to a significant True Polar Wander during this period. Though much more difficult to match with the ChRM and geological characteristics, the only possible alternative interpretation for the Ikniouen data should be a chemical remagnetization acquired during the Late Cretaceous - Early Paleocene times.

    Description: The North China Plain (NCP), with an area of ~170,000 square kilometers, is among the most important agricultural producing bases in China. In addition to canal irrigation with surface water from the Yellow River, the NCP also needs much groundwater for intensive irrigation. Spatiotemporally continuous and daily evapotranspiration (ET) estimates of high spatial resolution could be valuable for improving our understanding of agricultural water consumption across the NCP, and also for improving water use efficiency for better agricultural water resource management practices over similar regions globally. This ET data set at 1 km spatial resolution and daily timescale across the NCP from Jan 2008 to Dec 2019 was generated using two source energy balance model (TSEB) and data fusion. The accuracy is generally comparable and even higher than published results, with our ET data set featuring spatiotemporal continuity and high spatial resolution for a decade. Furthermore, this data set and associated approaches are valuable for performing daily, monthly, seasonal, interannual, and trend analyses of ET in the NCP and similar regions globally.

    Description: GRACE-FO carries a magnetometer as part of its attitude orbit control system (AOCS). The magnetometer does not belong to the scientific payload of the mission. However, after postprocessing of the data, information on the geomagnetic field and on electric currents in near Earth space are derived. Each GRACE-FO satellite (GF1 and GF2) carries two fluxgate magnetometers (FGM), an active one, FGM A, and a redundant one, FGM B. So far, the redundant magnetometers were not switched and are not included in the data set. The provided data consists of raw magnetic field data as provided by L1b (RAW), Magnetic field data aligned, calibrated and corrected (ACAL_CORR), CHAOS7 magnetic model predictions for core, crustal and large-scale magnetospheric field (CHAOS7), Magnetic coordinates (APEX) and Radial and field-aligned currents derived from magnetic data in ACAL_CORR (FAC). The data are provided in NASA CDF format (https://cdf.gsfc.nasa.gov/).

    Description: Abstract
    Description: This document is a "primer". This means that it is meant to prepare projects in the CRC "Future Rural Africa" for discussions on the degree of universality and cultural relativity of future concepts. As a primer it does not provide a conclusion or closure of scholarly debates in the field but its function is to open up and to facilitate these debates. The document consists of two parts. The first, shorter, part is based on a short presentation that the author did at the onset of the interdisciplinary work in the CRC (back in 2017) and it primarily provides a brief model of how to conceive of interdisciplinarity in a collaborative research centre concerned with the study of future. The second part of the document was written towards the end of the first phase of the CRC and contains some concrete examples of debates on concepts of time and future. There is no claim to be comprehensive here since there has recently been a considerable boost in studies on the cognitive foundations of time and related domains such as space and causality. While case material from Africa has increasingly been included in these debates, much of the attention is devoted to underlying questions of cognition and linguistic relativity and not so much to the descriptions of diversity and similarity in concepts of time and future. The study of cultural relativity with regard to time concepts which flourished initially in anthropology and linguistics has now been shifted to research in economics and neighbouring disciplines that have a practical interest in development - which also happen to be the interdisciplinary fields that are relevant in the CRC. Abstract linguistic distinctions such as that between weak FTR (Future Time Reference) and strong FTR languages become associated with concrete cultural differences of leading a healthy life and saving for the future. This contribution looks critically at these typologies with reference to African case studies and it argues that research would benefit from a closer combination between descriptions of African case material and comparative issues. It is also noteworthy that the discussions often center around the notion of "time" rather than "future" but typically the one is implicated in the other so that many underlying arguments can be read for both, time and future.

    Description: Airborne radar soundings of internal reflection layers were collected across the Pine Island (PIG) catchment area, West Antarctica, aboard the Polar 5 aircraft between 01 and 03 Dec 2014. An isochronal reflection layer was traced for a total distance of 2367 km to determine annual mean surface mass balance (SMB) for the period from approx. Nov 2004 to Dec 2014. Vertical firn density profiles were collected during the same measurement season along the flight track in the frame of the iSTAR campaign by means of Neutron Probe (NP) measurements. Annual markers were extracted from these profiles and used for the layer dating. A regional scale density-depth profile was estimated from all NP measurements and used for the conversion of two-way travel times (TWT) of the traced layer to mean annual SMB. Catchment wide SMB interpolation estimates were calculated by means of an ordinary logarithmic kriging (OLK) algorithm, which is applied to the alongtrack SMB estimates. Due to a data gap in the southern interior of PIG, complementary SMB estimates from RACMO (doi:10.5194/tc-12-1479-2018) and MAR (doi:10.5194/tc-14-229-2020) regional climate models were used to produce a catchment wide mean annual SMB map. Amongst others, total mass input can be derived from this map to assess the mass balance of PIG for the considered SMB averaging period. This dataset includes the level 1b processed radargrams, the traced layer in units of TWT and mean annual SMB, and SMB OLK maps. The latter include error grids as well as the partitioning map between OLK SMB estimates and complementary simulated SMB estimates for the PIG catchment area.

    Description: This data set consists of the airborne measurements obtained in the framework of the AWI-campaign "SpringTime Atmospheric Boundary Layer Experiment" (STABLE) that are used as supplement for the study by Michaelis et al. (2020). The measurements were performed in the atmospheric boundary layer near three different leads in the Arctic Marginal Sea Ice Zone north and northwest of Svalbard on 10, 25 and 26 March 2013. All cases represent conditions of a nearly lead-perpendicular convective flow over the leads. For each of the three cases, different flight legs are provided (see filenames): (a) 'upwind': a vertical profile performed upwind of the lead (b) 'cross-lead': a low-level horizontal flight leg performed across the lead along the mean wind direction (c) 'lead-parallel': lead-parallel flight legs performed at different distances to the upwind lead edge at different altitudes, either above the lead or further downwind (d) 'saw-tooth': a saw-tooth flight pattern performed across the lead along the mean wind direction (only for 25 March) (e) 'lead-parallel_avg-val_fluxes': flight-leg-averaged values of mean atmospheric quantities and turbulent fluxes for the lead-parallel legs The measurements of wind, temperature, pressure and humidity were performed with instruments mounted on a 3m long nose-boom of the research aircraft Polar 5 (see also Tetzlaff et al., 2015). For the three wind components, temperature, and pressure, the sampling rate is 100Hz so that with the observed ground speed of the aircraft of 40 to 75 ms-1 a spatial resolution of approximately 0.4 to 0.75m was obtained (Tetzlaff et al., 2015, Michaelis et al., 2020). The three wind components and air pressure were measured using a five hole probe. Air temperature was measured with a PT-100 resistance thermometer. Relative air humidity was measured with a dew point mirror. Global Position System (GPS) and Inertial Navigation System (INS) were used to derive height and position of the aircraft. In addition, a KT-19 radiation thermometer and an infrared (IR) scanner were used to measure surface temperatures. All data is adjusted to the time measured at the nose-boom. The turbulent fluxes were calculated using the eddy covariance method for all lead-parallel flight legs (see Tetzlaff et al., 2015, Michaelis et al., 2020). Mean values averaged over an entire flight leg and the corresponding statistical error are provided for air temperature, air density, horizontal wind speed, the sensible heat flux, the absolute value of the total vertical flux of horizontal momentum, and for the x- and y-components of the latter quantity. A more detailed description on the measurement techniques and flight patterns is provided by Tetzlaff et al. (2015). For more details on the post-processing of the raw data and on measurement accuracy, see Hartmann et al. (2018).

    Description: The drilling of the 10.5 m high Nori pingo that stands at 32 m asl in Grøndalen Valley (Spitsbergen) performed in April 2019 reached a depth of 21.8 m bs (core #13, starting from 42.5 m asl, 77.99483 °N, 14.59009 °E) and revealed 16.1 m thick massive ice. The core was obtained with a portable gasoline-powered rotary drilling rig (UKB 12/25, Vorovskiy Machine Factory, Ekaterinburg, Russia). The core pieces with diameter 112-76 mm were lifted for sampling to the surface every 30–50 cm. After documentation and cryolithological description core pieces were sealed in zip lock bags. Ice samples were split in two parts - one part for stable isotope analyses, another part for ion content measurement. They were kept frozen for transportation while sediment samples were kept unfrozen. Moisture content was analyzed in laboratory by measuring sediment samples weight before and after drying. The stable water isotope composition (δ18O and δD) of massive pingo ice was analyzed at the Climate and Environmental Research Laboratory (CERL, Arctic and Antarctic Research Institute, St. Petersburg, Russia) using a Picarro L2120- i analyzer. After every five samples the working standard (SPB-2, δ18O = -9.66 ‰ and δD = -74.1 ‰) was measured. SPB-2 is made of distilled St. Petersburg tap water and is calibrated against the International Atomic Energy Agency (IAEA) standards VSMOW-2 (Vienna Standard Mean Ocean Water 2), GISP (Greenland Ice Sheet Precipitation), and SLAP-2 (Standard Light Antarctic Precipitation 2). The reproducibility of the results is 0.08 ‰ for δ18O and 0.4 ‰ for δD and was assessed by re-measuring a random selection of 10% of the total samples. The measurement error is thus 1-2 orders of magnitude less than the natural isotopic variability of pingo ice, which is satisfactory for the purpose of this study. The δ18O and δD values are given as per mil (‰) difference to the VSMOW-2 standard. The deuterium excess (d) is calculated as d = δD - 8δ18O29. The ion content of sedimentary permafrost samples from core #13 was estimated after water extraction at the analytical laboratory of RAE-S, Barentsburg. The material was dried and sieved at 1 mm. About 20 g of the sediment were suspended in 100 ml of de-ionized water and filtered through 0.45 μm nylon mesh within 3 minutes after stirring. Electrical conductivity (EC, measured in μS cm-1) and pH values were estimated with a Mettler Toledo Seven Compact S 220. EC values were transformed automatically by the instrument into general ion content (mineralization) values given as mg L-1. Major anions and cations in the water extracts were analyzed by an ion chromatograph (Shimadzu LC-20 Prominence) equipped with the Shimadzu CDD-10AVvp conductometric detector and ion exchange columns for anions (Phenomenex Star-ion A300) and for cations (Shodex ICYS-50). Bicarbonate content was measured by a Shimadzu TOC-L analyzer via catalytic oxidizing at +680o C and subsequent infrared detecting. Melted pingo ice samples from core #13 and spring water samples were analyzed after filtration through 0.45 μm nylon mesh on the same equipment using the same techniques for pH, EC, and ion composition as for sedimentary permafrost samples. Analyses and research were aimed at determining major characteristics of the Nori pingo including its internal structure, groundwater source, and geochemical and isotopic stages of formation.

    Description: This dataset includes all the Fe(II) measurements carried out during the LOHAFEX ocean iron fertilization (January- March 2009) in waters of a stable eddy located in the Atlantic sector of the Southern Ocean. Data serve the purpose to compare the effect of physicochemical and biological variables in changes in the proportion of Fe(II)/Fe(III) concentrations during the development of a flagellate/copepod bloom. Measurements were performed with a flow injection system where seawater is mixed with an alkaline luminol solution that emits lights proportionally to the concentration of reduced iron (Fe(II)). Data are split in one file showing Fe(II) concentrations before and after filtration through 0.2 mm in the upper 200 m of the water column and several files showing Fe(II) concentrations in unfiltered seawater collected with the underway sampling (11 m deep) while sailing across the fertilized patch. This is the first data sets that address the contribution of particles to Fe(II) concentrations in seawater. Transect Fe(II) data are accompanied by photosynthetic quantum efficiency (FV/FM) and chlorophyll-a data that allow the precise location of the fertilized patch edge.

    Description: The Indonesian Throughflow (ITF), as the sole low-latitude conduit connecting the Pacific and Indian Oceans, regulates the thermohaline balance between these oceans. Investigating the spatio-temporal variability of the ITF and its relationship to precessional forcing is, thus, crucial for understanding the drivers of tropical climate change. Here, we reconstruct the history of the ITF over the past ~120 kyr, based on high resolution (~400 yr) δ18O and Mg/Ca records of Globigerinoides ruber and Pulleniatina obliquiloculata from Core SO217-18540 retrieved from the Flores Sea upwelling region within the main pathway of the ITF. Comparison of these new records with published paleo-oceanographic and climatological data from the western tropical Pacific suggests that annual mean conditions in the Flores Sea were controlled by the ITF rather than by monsoonal upwelling. Our results further indicate that precessional insolation was a major forcing for the hydrological evolution of the ITF during the past 120 kyr. We suggest that precessional insolation forcing paced ITF variability by modulating the mean state of El Niño-Southern Oscillation-like conditions and latitudinal shifts or expansion/contraction of the Intertropical Convergence Zone.

    Description: To identify the processes mainly controlling the Nd isotopic composition and concentration along a transect from the Equatorial to the North Pacific and to assess the suitability of Nd isotope compositions to trace water mass advection and mixing in this region, we collected filtered seawater samples from full water column profiles conducted along a transect from 7°S, 179°W to 52°N, 168°E. The samples were recovered during RV Sonne cruise SO264 in July and August 2018 using 24 non-metallic 10 litre Niskin bottles mounted on a frame equipped with a SBE 9plus CTD profiler (Sea-Bird Electronics Inc.) and two oxygen sensors (SBE 43 oxygen self-regenerative Clark-sensors with Teflon membrane). The dataset includes the dissolved radiogenic Nd isotope and concentration data of 57 seawater samples, which provide important information on the formation, advection and mixing of different water masses.

    Description: These datasets contain the color and grain size data for trenches 3, 3A, and 5 of the At site described in Nett et al. (2021). Sampling depths and laboratory numbers are given. Grain size was measured with a Laser Diffraction Particle Size Analyzer (Beckman Coulter LS 13 320) calculating the percentaged size frequency of 116 classes within a size range of 0.04–2000.00 µm (2% uncertainty). The measurement accuracy was increased by measuring each sample four times in two different concentrations. The grain size distributions were determined using the Mie theory (ISO International Standard 13320, 2009; Fluid RI: 1.33; Sample RI: 1.55; Imaginary RI: 0.1; Özer et al., 2010; cf. Schulte et al., 2016). The colorimetric properties of the sediments were determined as described in e.g. Eckmeier et al. (2013) and Vlaminck et al. (2016) using a Konica Minolta CM-5 spectrophotometer after the samples were homogenized and dried. The L*a*b* values indicate the extinction of light, on a scale from L* 0 (absolute black) to L* 100 (absolute white) and express color as chromaticity coordinates on red-green (a*) and blue-yellow (b*) scales.

    Description: Abstract
    Description: This data publication provides supplementary data to the X9_2015 network that was operated from 2015 until 2016 within the KISS experiment in the area of the Klyuchevskoy Volcanic Group. In addition, the associated seismic waveform data are archived in the GFZ GEOFON archive with the https://doi.org/10.14470/K47560642124 (Shapiro et al., 2015) and the associated Scientific Technical Report – Data (Green et al., 2021, https://doi.org/10.48440/GFZ.B103-21019). Please refer to this site for any further information. Data in the KISS experiment was mainly recorded by Cube3 digitizers which requires a conversion into standard seismological formats including a resampling to adjust the timing of the data to the GPS signals. The data in the GEOFON archive does therefore already include some degree of processing and some loss of information contained in the GPS tags of the raw data. We therefore provide a copy of the raw data as it was retrieved from the Cube digitizers (www.gfz-potsdam.de/gipp → Instruments). Additionally, we provide raw data from the Baikal digitizers and photographs of the sites from the station collection.

    Description: Abstract
    Description: This dataset comprises numerical outputs from the thermosphere-ionosphere-electrodynamics general circulation model (TIE-GCM) simulations described in the article "Modeling of planetary wave influences on the pre-reversal enhancement of the equatorial F region vertical plasma drift" (Yamazaki & Diéval, 2021).
    Description: Methods
    Description: The TIE-GCM is a numerical model of the coupled thermosphere-ionosphere system (Richmond et al., 1992; Qian et al., 2014). In Yamazaki & Diéval (2021), the model was run under geomagnetically quiet (Kp=1) and high solar-flux (F10.7=200) conditions. The lower boundary of the model at ~97 km was specified with the the thermosphere-ionosphere-mesosphere electrodynamics general circulation model (TIME-GCM) (Roble & Ridley, 1994), which itself was constrained by the data from the Modern Era Retrospective-analysis for Research and Applications (MERRA) (Reinecker et al. 2011) for the year 2009. In this way, the TIE-GCM is able to reproduce effects of atmospheric forcing from the lower and middle atmosphere. In addition to the simulation described above, which are referred to as "reference", Yamazaki & Diéval (2021) performed two other simulations with modified lower-boundary forcing. They are referred to as "no_PW" and "tides_only". See Yamazaki & Diéval (2021) for descriptions of different cases. The simulation results from these three cases are saved in separate files in a MATLAB format with a .mat extension. The model outputs from "reference", "no_PW", and "tides_only" cases can be found in "reference.mat", "no_PW.mat", and "tides_only.mat", respectively. Each file contains the following variables: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ doy [365 x 1 ]: day of year longitude [1 x 144]: longitude (degrees) PRE_Vz[365 x 144]: intensity of pre-reversal enhancement (m/s) PRE_LT[365 x 144]: local time of pre-reversal enhancement (hours) +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Descriptions of how PRE_Vz and PRE_LT are determined can be found in Yamazaki & Diéval (2021).
