    Description: This report analyses the international climate negotiations at the UN climate conference in Warsaw in November 2013. The report covers the discussions under the Durban Platform on developing a new comprehensive climate agreement by 2015 and increasing short-term ambition as well as the issues relating to near-term implementation of previous decisions in the areas of emission reductions and transparency, adaptation, loss and damage, finance and technology. The report concludes that Warsaw once again starkly highlighted the sharp divisions and lack of trust among countries. Industrialised countries' collective lack of leadership strongly contributed to re-opening the traditional North-South divide. As a result, on many issues the outcomes hardly go beyond the lowest common denominator. The conference only agreed on the bare minimum to move the 2015 process forward and also made no headway in strengthening short-term ambition. Some progress was made with the establishment of the "Warsaw international mechanism for loss and damage associated with climate change impacts" and the completion of the rules for reducing emissions from deforestation and forest degradation. However, here as well further substance, in particular financial support from industrialised countries, is required to actually fill these mechanisms with meaning. If countries want to escape from groundhog day, they will have to start seeing and utilizing the UN climate process rather differently.

    Description: In recent years, policies to promote renewable energy have become increasingly popular among municipalities in different parts of the world. This article examines the case of Germany. It argues that municipalities, compared to other state and private actors, already have the potential to play a key role in German renewable energy governance. Although both private actors and the European Union have gained importance in the past 20 years, German municipalities still play a crucial role and can apply five distinct and important modes of governance in the field of renewable energy policy. In this regard, the notion of a general development towards a "cooperating and ensuring state", which increasingly delegates its tasks and thus becomes less important, cannot be confirmed in the field of municipal renewable energy governance in Germany.

    Description: Our perception of design is changing, for design today is no longer concerned only with aesthetics. Now the key factors are interdisciplinary competence and approaches to problem solving. Both politicians as well as businesses recognise design's hybridity and increasingly implement it as a driver of sustainable development (see Chap. 2: Design as a Key Management Factor for Sustainability). But what exactly does "sustainability" mean? What does it mean in this specific context? People must make use of natural resources to meet their basic needs. In this process, resources are transferred into commercial circulation and usually transformed into products with a particular function. Yet the environment is limited and humanity uses more resources than the Earth can sustainably provide. It is time to rethink and generate the same usage while consuming fewer resources (see Chap. 3: Environmental Space - Challenging Transitions). Most countries have incorporated sustainability strategies into their political agendas in order to counteract the threats of climate change caused by the overuse of natural resources, high CO2 emissions, and other factors. The indicators for these strategies vary greatly from country to country (see Chap. 4: Sustainability - Challenges, Politics, Indicators). These indicators need to be taken into account if we are to successfully implement a product or service within a specific context. A concept can only be successful when country-specific indicators are taken into account and the societal context is incorporated into the plan right from the start. The goal is to develop services that support national sustainability targets in production and consumption systems (see Chap. 5: Managing Sustainable Development). When it comes to companies, these changes can simply be introduced in the form of services or products. In the end, it is the users who decide on the success or failure of innovative solutions by either integrating them into their daily lives or ignoring them. Solutions will only be integrated into users' lives when their role within the social framework remains unchallenged by behavioural transformations caused by use of the solution. In order for users to be able to adopt innovations, sustainable development must take place simultaneously on many different levels. These multi-levelled transitions allow for the transformation of society as a whole. Designers can act as agents of change by providing the needed innovations (see Chap. 6: Transition Requires Change Agents for Sustainability). If we are to develop suitable solutions and new approaches, the real needs have to be analysed at the beginning of the development process. New physical products, which frequently result in auxiliary products, are often developed without taking into account the overall context, whereas the development of service-orientated solutions is ignored. A physical product is not absolutely necessary. A service (which is naturally dependent on physical products) can usually fulfil the need just as well - or perhaps even better and at a lower cost – while using fewer or no resources (see Chap. 7: Needs & Services - An Approach). There are a variety of possible approaches to integrate sustainability into the design process (see Chap. 8: Design Process). Precisely which solution is "most or more sustainable" (this is dependent on the defined targets and the indicators used) is often not immediately obvious, and we must turn to a set of methods for a transparent and tangible assessment (see Chap. 9: Sustainability Assessment in Design - Overview and Integration of Methods).

    Description: Another summit of change, known as Rio+20, has passed in summer 2012, nourishing the rumours of a green economy. Building up a green economy seems to be the all over recipe for different crises of capitalism, among them climate change and resource scarcity. Yet efficiency and consistency, as their main strategies, do not suffice to reach sustainable levels, as they cause rebound effects and keep stimulating economy growth. Obviously, there are limits to green growth, too. Can we conceive an economy, and respective economic institutions, that serve human needs and wealth without a built-in necessity to grow? What kind of political, mental, and individual changes does a sufficiency economy require? And what are perspectives and policies to actually start implementing it? Just before Rio +20 the symposium "Economy of Sufficiency", devoted to Wolfgang Sachs on the occasion of his 65th birthday in 2011, examined these questions in three dimensions. Accordingly this selection of contributions to the symposium follows the chapters "Wealth in diversity" (Ashok Khosla, Marianne Gronemeyer, Vandana Shiva), "Enjoyable limits" (Richard B. Norgaard, Tim Jackson) and "Creating commons" (Ezio Manzini, Silke Helfrich). The essays indicate the historical development of the ideas on a sufficiency economy. Wandering through discourses of sustainable development for several decades, the authors map the range of perspectives, practices as well as barriers and bridge them between cultures, agencies and schools.

    Description: Py4HIP is an open-source software tool for Heat-In-Place calculations implemented as a self-explanatory Jupyter notebook written in Python (Py4HIP.ipynb) Calculating the Heat In Place (HIP) is a standard method for assessing the geothermal potential for a defined geological unit (e.g., Nathenson, 1975; Muffler and Cataldi, 1978; Garg and Combs, 2015). The respective implementation in Py4HIP is based on a volumetric quantification of contained energy after Muffler and Cataldi (1978), where the geological unit at hand is considered spatially variable in terms of its temperature, thickness, porosity, density and volumetric heat capacity of its solid and fluid (brine) components.

    Description: The airborne hyperspectral image was acquired by the AVIRIS-Next Generation (AVIRIS-NG) instrument during the AVIRIS-NG Europe 2021 HyperSense campaign that has been conducted as a joint effort of ESA, NASA/JPL and the University of Zurich. Acquired was an agricultural area near Irlbach, Germany on May 30th, 2021. The data was preprocessed (radiometrically, geometrically and atmospherically corrected) to contain 419 bands in the 402 - 2495 nm spectral range. Metadata was acquired on the same day for the variables Leaf Area Index (LAI), Leaf Chlorophyll content, crop height and phenology. An overview of metadata acquisition and processing can be found in the HYPERedu YouTube videos on ground reference data acquisition in the field and ground reference data acquisition in the lab. More details on LAI and chlorophyll acquisition can be found in the field data guides assembled by the authors of this dataset via enmap.org (Danner et al., 2015; Süß et al., 2015). The dataset is made publically available within the massive open online course (MOOC) "Beyond the Visible - Introduction to Imaging Spectroscopy for Agricultural Applications", available from December 2022.

    Description: This dataset provides friction data from ring-shear tests on feldspar sand FS900S used for the simulation of brittle behaviour in crust- and lithosphere-scale analogue experiments at the Tectonic Modelling Laboratory of the University of Bern (Zwaan et al. in prep; Richetti et al. in prep). The materials have been characterized by means of internal friction parameters as a remote service by the Helmholtz Laboratory for Tectonic Modelling (HelTec) at the GFZ German Research Centre for Geosciences in Potsdam (Germany). According to our analysis both materials show a Mohr-Coulomb behaviour characterized by a linear failure envelope. Peak, dynamic and reactivation friction coefficients of the feldspar sand are μP = 0.65, μD = 0.57, and μR = 0.62, respectively, and the Cohesion of the feldspar sand is in the order of 5-20 Pa. An insignificant rate-weakening of less than 1% per ten-fold rate change is registered for the feldspar sand. Granular healing is also minor.

    Description: This dataset includes five stations of an Ocean Bottom Seismometer (OBS) experiment conducted at the southern end of the Fonualei Rift and Spreading Center in the Lau Basin, southwestern Pacific. The OBS recorded continuously for 32-days on 4 components, including a hydrophone and a 3-component 4.5 Hz geophone. The experiment was conducted during RV Sonne cruise SO267, project ARCHIMEDES I. In the article, the authors report an increasing trend of methane emissions for June and July at a permafrost site in Siberia (Lena River Delta). Using the longest set of observational methane flux data in the Arctic, the authors demonstrate that the continuous warming has begun to trigger the projected enhancement of methane release in Arctic permafrost ecosystems. This software is written in MATLAB. Running the codes ([.m files](Code)) and loading the data files ([.mat files](Data)) requires the pre-installation of [MATLAB](/https://de.mathworks.com/products/matlab.html). IMPORTANT: The repository only contains dummy data. The data that is needed to run the code can be requested by Torsten Sachs and Christian Wille (contact authors). Although the scripts and the data files have been tested for newer versions of MATLAB (〉= MATLAB R2017a). The code might also run in older versions of MATLAB, but this has not been tested.

    Description: Orbital products describe positions and velocities of satellites, be it the Global Navigation Satellite System (GNSS) satellites or Low Earth Orbiter (LEO) satellites. These orbital products can be divided into the fastest available ones, the Near Realtime Orbits (NRT), which are mostly available within 15 to 60 minutes delay, followed by Rapid Science Orbit (RSO) products with a latency of two days and finally the Precise Science Orbit (PSO) which, with a latency of up to a few weeks, are the most delayed. The absolute positional accuracy increases with the time delay. This dataset compiles the RSO products for various LEO missions and the appropriate GNSS constellation in sp3 format. The individual solutions for each satellite mission are published with individual DOI as part of this compilation. GNSS Constellation: • GNSS 24h (v01) • GNSS 30h (v02) LEO Satellites: • CHAMP • GRACE • GRACE-FO • SAC-C • TanDEM-X/ TerraSAR-X Each solution is given in the Conventional Terrestrial Reference System (CTS). • The GNSS RSOs are 30-hour long arcs starting at 21:00 the day before the actual day and ending at 03:00 the day after. The accuracy of the GPS RSO sizes at the 3-cm level in terms of RMS values of residuals after Helmert transformation onto IGS combined orbit solutions (Version 1 GNSS RSOs are 24-hour long arcs starting at 00:00 and ending at 24:00 the actual day). • The LEO RSOs are generated based on these 30-hour GNSS RSOs in two pieces for the actual day with arc lengths of 14 hours and overlaps of 2 hours. One starting at 22:00 and ending at 12:00, one starting at 10:00 and ending at 24:00. The accuracy of the LEO RSOs is at the level of 1-2 cm in terms of SLR validation. The exact time covered by an arc is defined in the header of the files and indicated as well as in the filename. This dataset compiles RSO products for various LEO missions and the corresponding GNSS constellation in sp3 format in a revised processing version 2. The switch from previous version 1 to 2 was performed on 18-Feb-2019. Major changes from version 1 to 2 are the change from IERS 2003 to IERS 2010 conventions and ITRF 2008 to ITRF-2014, as well as the temporal extension of the GNSS constellation from previous 24 hours (version 1) to 30 hours (version 2) arcs. This temporal expansion eliminates the chaining of two consecutive 24-hour GNSS constellation solutions previously used to process day-overlapping LEO arcs in Version 1. This 24h GNSS constellation (Version 1) will continue to operate and be stored on the ISDC ftp server, as discussed in more detail in Section 8.1. All RSO LEO arcs will no longer be continued in version 1 after the changeover date and will only be available in version 2 since then.

    Description: The WHU-GRACE-GPD01s models are the latest monthly gravity field solutions recovered from GRACE intersatellite geopotential difference (GPD) data processed at the School of Geodesy and Geomatics, Wuhan University, China. The intersatellite GPDs are estimated from GRACE Level-1B (RL03) data based on the improved energy balance equation and remove-compute-restore (RCR) technique, and the background models are consistent with GRACE Level-2 processing standards document (RL06). Further details are presented in Zhong et al. (2020, 2022). The WHU-GRACE-GPD01s models include two sets of GRACE monthly solutions: one is the unconstrained monthly solutions with the maximum degree and order of 60, the other is the constrained monthly solutions up to the maximum degree and order 96 with Kaula regularization constraint, and the optimal regularization parameter is determined using variance component estimation (VCE). This work is supported by the National Natural Science Foundation of China (No. 41974015, 41474019, 42061134007) and the Project Supported by the Special Fund of Hubei Luojia Laboratory (Grant No. 220100004).

    Description: The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy. IGETS continues the activities of the Global Geodynamics Project (GGP) between 1997 and 2015 to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network. As part of this network, the Onsala station (code OS, instrument GWR OSG 054) was established in 2009 thanks to the financial support of the Committee for Infrastructure of the Swedish Research Council, until 2021, and of the Swedish geodetic survey Lantmäteriet since 2021. Continuous time-varying gravity and atmospheric pressure data from OS are integrated in the IGETS data base hosted by ISDC (Information System and Data Centre) at GFZ. The OS station (longitude: 11.9266 E; latitude: 57.3858 N and elevation: 7.93 m) is located at the Onsala Space Observatory, south of Gothenbourg, a well instrumented site for geodetic and meteorological studies (https://www.chalmers.se/en/researchinfrastructure/oso/Pages/default.aspx). An air-circulation system controls the humidity and temperature in the gravimeter house and there are 3 pillars available. Absolute gravity measurements are done every year by Lantmäteriet. - The time series of gravity and barometric pressure started in July 2009 and is going on. - The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 minute. For a detailed description of the IGETS data base and the provided files see Voigt et al. (2016, http://doi.org/10.2312/GFZ.b103-16087). Rainfall data are also provided as auxiliary data to IGETS database. OS data are used in conjunction with projects of the Nordic Geodetic Commission (NKG) - Working Group for Geodynamics (https://www.nordicgeodeticcommission.com/working-group-of-geodynamics/). Interactive graphs are available at https://lab3.oso.chalmers.se/wx/gravimeter_data/

    Description: This dataset provides results from rheological tests of glucose syrup from two suppliers tested within the EPOS Multi-scale Laboratories (MSL) trans-national access (TNA) program 2019 at the Laboratory of Experimental Tectonics (LET), Univ. Roma TRE, Italy. Syrups Glucowheat 45/81 (GW45) and Glucowheat 60/79 (GW60) are produced by Blattmann Schweiz AG, Switzerland (2019 batch). Syrups GlucoSweet 44 (GS44) and GlucoSweet 62 (GS62) are produced by ADEA (Amidi Destrini ed Affini), Italy (2019 batch) . The four tested glucose syrups are labeled according to their DE value (dextrose equivalent value). For tested products from Blattmann Schweiz AG, the second number refers to the weight percentage of dry substance. Glucose syrup GS44 is used in full lithospheric scale analogue experiments at the Tectonic Modelling Lab (TecLab) at the University of Bern, Switzerland as a low-viscosity material simulating the asthenospheric mantle lithosphere to provide isostatic equilibration. The materials have been analyzed using a MCR301 Rheometer (Anton Paar) equipped with parallel plates geometry and rotational regime . To prevent the evaporation of the samples during the measurements, an external water-lock device has been used.

    Description: Ireland Array is an array of 20 broadband seismometers that was operated by the Dublin Institute for Advanced Studies across the Republic of Ireland. The array comprised up to 20 stations running simultaneously, all equipped with Trillium 120PA seismometers and Taurus data loggers. The 20 stations were installed in 20102012. Some of the stations were moved to new locations in Ireland in the course of the operation of the array, either in order to enhance the data sampling of the island or when the old deployment sites became unsuitable. Ireland Array dramatically increased the seismic data sampling of Ireland and enabled advances and discoveries in the studies of the structure and evolution of Ireland’s crust and lithosphere, seismicity of Ireland, and mechanisms of the Paleogene intraplate volcanism in Ireland and surroundings.

    Description: Project SWEAP (Southwest Indian Ridge Earthquakes and Plumes), a collaborative effort led by the Alfred-Wegener-Institute, installed a network of 10 broad-band ocean bottom seismometers (OBS) along the ultraslow-spreading Oblique Supersegment of the Southwest Indian Ridge. The presented data set covers the continuous records of 8 stations of the network provided by the DEPAS instrument pool. One station of the original network could not be recovered, another one did not return data. The instruments were spaced at roughly 15 km intervals in a triangular shape network to either side of the rift axis covering about 60 km along axis between 13°E and 13.8°E and 60 km across axis between 52°S and 52.6°S. The determination of the OBS positions is described by Schmid et al. (2016). The network design was optimized for detecting and locating deep seismicity in the area. The rift valley was filled with soft silica ooze, producing considerable delay of S-phases at selected stations. Instrument deployment started during RV Polarstern cruise ANT-XXIX/2 on December 05 2012. Instrument recovery was completed during RV Polarstern cruise ANT-XXIX/8 on November 26 2013. 5 Refraction seismic lines were acquired by RV Polarstern cruise ANT-XXIX/8 from November 17 to 19 in 2013. All OBS could be synchronized with the GPS clock upon recovery such that skew values describing the clock drift are available for all stations. The non-linear clock drift of station SWE05 was determined by means of noise cross-correlations and applied to the data set. All other stations show a linear drift, which was corrected.

    Description: Gakkel Deep is a pilot project that installed a network of four broadband ocean bottom seismometers (OBS) near Gakkel Deep, the deepest depression in the Arctic Ocean, at the eastern end of the ultraslow spreading Gakkel Ridge. The area is covered year-round by sea ice. In order to enable a safe recovery of the OBS in a sea ice covered ocean, the OBS were modified to include a positioning system that allows to track the instruments at meter accuracy during descent and ascent and when stuck beneath ice floes. This pilot studied aimed at testing the recovery procedure of the OBS, checking the performance of the modified instrument design, getting an overview of ambient seismic noise at the bottom of the Arctic Ocean and at contributing to a better understanding of the origin of the Gakkel Deep depression with more than 3000 m of topography. The network is shaped as a rectangle with 8 km and 10 km side length and is centered at about 82°N 119.5°E at water depths between 3600 m and 4100 m. It is positioned slightly to the east of the present plate boundary in an area with volcanic structures. Instruments from the German Instrument Pool of Amphibian Seismology (DEPAS) were deployed during RV Polarstern cruise PS115/2 on September 15, 2018. Instrument recovery was completed during RV Polarstern cruise PS122/1 on September 27, 2019. The data set contains about 377 days of continuous records at 250 Hz sample rate. The station locations were determined with Ultra Short Baseline (USBL) ranging, the accuracy is approx. 10 m. The non-linear clock drift was determined by means of noise cross-correlations and applied to the data set.
