    Publication Date: 2018
    Description: 〈b〉Stochastic downscaling of precipitation in complex orography: a simple method to reproduce a realistic fine-scale climatology〈/b〉〈br〉 Silvia Terzago, Elisa Palazzi, and Jost von Hardenberg〈br〉 Nat. Hazards Earth Syst. Sci., 18, 2825-2840, https://doi.org/10.5194/nhess-18-2825-2018, 2018〈br〉 This study proposes a modification to a stochastic downscaling method for precipitation, RainFARM, to improve the representation of the statistics of the daily precipitation at fine scales (1 km) in mountain areas. This method has been demonstrated in the Alps and it has been found to reconstruct small-scale precipitation distribution. It can be employed in a number of applications, including the analysis of extreme events and their statistics and hydrometeorological hazards.

    Description: 〈b〉Soil lacquer peel DIY: simply capturing beauty〈/b〉〈br〉 Cathelijne R. Stoof, Jasper H. J. Candel, Laszlo van der Wal, and Gert Peek〈br〉 SOIL Discuss., https//doi.org/10.5194/soil-2018-27,2018〈br〉 〈b〉Manuscript under review for SOIL〈/b〉 (discussion: final response, 2 comments)〈br〉 Teaching and outreach of soils is often done with real life snapshots of soils and sediments in lacquer or glue peels. While it may seem hard, anyone can make such a peel. Illustrated with handmade drawings and instructional video, we explain how to capture soils in peels using readily available materials. A new twist to old methods makes this more safe, simple and successful, and thus a true DIY (do it yourself) activity, highlighting the value and beauty of the ground below our feet.

Spatially, our estimations suggest a higher probability of extreme drought events in southern and central areas of Spain, compared to northern and eastern regions. Nevertheless, there are strong differences between drought indices, as well as among drought timescales.

The organic carbon stock content up to 1 m depth varied as follows: forest 〉 pasture 〉 continuous cropping, with no impact of the number of years under cropping. The incorporation of pastures of warm-season grasses was able to mitigate the decrease of C stocks caused by cropping and so could be considered sustainable management.

    Description: 〈b〉Bayesian earthquake dating and seismic hazard assessment using chlorine-36 measurements (BED v1)〈/b〉〈br〉 Joakim Beck, Sören Wolfers, and Gerald P. Roberts〈br〉 Geosci. Model Dev., 11, 4383-4397, https://doi.org/10.5194/gmd-11-4383-2018, 2018〈br〉 Seismic hazard assessment requires records of earthquake recurrence with many slip events. Current data from paleoseismology on individual faults are sparse and do not provide stable estimates of earthquake recurrence. We propose a statistical model-based method to study timings of earthquakes over the past few millennia. The results agree with historical earthquakes for faults in the Italian Apennines, and can aid future studies of fault interactions over multiple earthquake cycles.

We explore how they differ in their perceptions of flooding risk, desired project outcomes, and knowledge. We observe substantial differences among experts, and recommend formally acknowledging these perceptions when engaging in flood management.

Our results highlighted that exports depended on the intensity and stage of the bloom, the phytoplankton size and community structures. After comparing with primary production, we concluded that, during our study, the North Atlantic behaves like most of the highly productive areas in the world's ocean, with a low export efficiency.

Here, this premise is assessed from a pseudo-reality perspective by considering last millennium ensembles of simulations from the Community Earth System Model. The results show that long-term variations in the energy fluxes at the surface during industrial times, due to the influence of external forcings, impact the long-term air–ground temperature coupling.

The DGD reduces to instantaneous gravity drainage when a dimensionless parameter exceeds 500. A pseudo-steady state model excluding initial condition causes a time shift from the actual transient model in predicting simple harmonic motion of head fluctuation.

To understand the water origin in this desert, stable and radioactive isotopes and hydrochemistry of natural waters were investigated. The groundwaters in the desert were young but not of meteoric origin, i.e., out of control by the modern and palaeo- direct recharge. The tectonic control, but not the climate control, is essentially responsible for the water origin there.

The main finding is that radiative perturbation by the high dust loading does not necessarily cool the surface surrounding Antarctica.

This data is used by climate change mitigation and adaptation policies studies and stake holders. CORDEX requires a list of variables, which most of them are not provided by atmospheric models. Aiming to help the community and to maximize use of CORDEX exercises, we create a new module for the WRF model to directly produce them adding 〈q〉generic〈/q〉 and 〈q〉additional〈/q〉 ones.

Discuss., https//doi.org/10.5194/amt-2018-345,2018〈br〉 〈b〉Manuscript under review for AMT〈/b〉 (discussion: open, 0 comments)〈br〉 〈p〉This paper describes a neural network algorithm for the estimation of liquid water cloud optical properties from the Polarization and Directionality of Earth's Reflectances-3 (POLDER-3) instrument, on board the Polarization & Anisotropy of Reflectances for Atmospheric Sciences coupled with Observations from a Lidar (PARASOL) satellite. The algorithm has been trained on synthetic multi-angle, multi-wavelength measurements of reflectance and polarization, and has been applied to the processing of one year of POLDER-3 data. Comparisons of the retrieved cloud properties with Moderate resolution Imaging Spectroradiometer (MODIS) products show negative biases around −2 in retrieved cloud optical thicknesses (COTs) and between −1 and −2 μm in retrieved cloud effective radii. Comparisons with existing POLDER-3 datasets suggest that the proposed scheme may have enhanced capabilities for cloud effective radius retrieval at least over land. An additional feature of the presented algorithm is that it provides COT and effective radius retrievals at the native POLDER-3 Level 1B pixel level.〈/p〉

Model Dev., 11, 4399-4416, https://doi.org/10.5194/gmd-11-4399-2018, 2018〈br〉 In this study, based on a traceability analysis technique, we evaluated alternative representations of C–N interactions and their impacts on the C cycle using the TECO model framework. Our results showed that different representations of C–N coupling processes lead to divergent effects on plant production, C residence time, and thus the ecosystem C storage capacity. Identifying those effects can help us to improve the N limitation assumptions employed in terrestrial ecosystem models.

Earth Syst. Sci., 22, 5675-5695, https://doi.org/10.5194/hess-22-5675-2018, 2018〈br〉 This paper addresses questions related to the adoption of stochastic methods in hydrogeology, looking at factors such as environmental regulations, financial incentives, higher education, and the collective feedback loop involving these factors. We show that stochastic hydrogeology's blind spot is in focusing on risk while ignoring uncertainty, to the detriment of its potential clients. The imbalance between the treatments of risk and uncertainty is shown to be common to multiple disciplines.

To evaluate the parameterizations, a box model was developed to simulate SOA formation from monoterpenes and aromatics in the environmental chamber EUPHORE. This box model takes oligomerization, nonideality of the aerosol, multiphase partitioning, aging, vapor wall losses and particle-phase diffusion into account. All these phenomena are rarely taken into account together.

Climate and weather models often assume constant vegetation parameters because good measurements are missing. We used affordable accelerometers to measure tree sway of 19 trees in the Amazon rainforest. We show that trees respond very differently to the same weather conditions, which means that vegetation parameters are dynamic. With our measurements trees can be accounted for more realistically, improving climate and weather models.

Here, we present model simulations of this tide and investigate the relative importance of possible forcing mechanisms because they are still under debate. These are, besides direct solar heating, nonlinear interactions between other tides and gravity wave–tide interactions. As a result, solar heating is most important and nonlinear effects partly counteract this forcing.

    Description: 〈b〉Evaluation of atmospheric nitrogen inputs into marine ecosystems of the North Sea and Baltic Sea – part B: contribution by shipping and agricultural emissions〈/b〉〈br〉 Daniel Neumann, Hagen Radtke, Matthias Karl, and Thomas Neumann〈br〉 Biogeosciences Discuss., https//doi.org/10.5194/bg-2018-365,2018〈br〉 〈b〉Manuscript under review for BG〈/b〉 (discussion: open, 0 comments)〈br〉 The contribution of atmospheric nitrogen deposition to the marine dissolved inorganic nitrogen (DIN) pool of the North and Baltic Sea was assessed for the year 2012. Atmospheric deposition accounted for approximately 10 % to 15 % of the DIN but its residence time differed between both water bodies. The nitrogen contributions of atmospheric shipping and agricultural imissions also were assessed. Particularly the latter source had a large impact in coastal regions.

Chem. Phys., 18, 15705-15723, https://doi.org/10.5194/acp-18-15705-2018, 2018〈br〉 This article analyzes the health effects caused by changes in air pollution concentrations during the period of 1990–2015 in Stockholm, Gothenburg, and Malmö: the three largest cities in Sweden. The air pollutants that have been measured and analyzed are NO〈sub〉〈i〉x〈/i〉〈/sub〉, NO〈sub〉2〈/sub〉, O〈sub〉3〈/sub〉, and PM〈sub〉10〈/sub〉. NO〈sub〉〈i〉x〈/i〉〈/sub〉 and NO〈sub〉2〈/sub〉 exhibit decreasing trends during this period, with beneficial effects on public health. An overall conclusion is that public health can largely benefit from reduced air pollution levels.

Using two sets of geometry data from production calibration and return re-calibration, this algorithm can recover wind with/without transducer shadow correction and sonic temperature with crosswind correction, and then obtain fluxes at quality as expected. This study is applicable as a reference for related topics.

We find that vertically migrating phytoplankton, which traverse ~ 100–150 m in the upper ocean over days to acquire nutrients from waters at depth and return to the surface for photosynthesis, likely explain the observed anomalies and help sustain surface ocean productivity and the biological pump throughout the annual cycle in the subtropical ocean.

Our goal is to find how site and region representative the model outputs are. This is a question of interest as some of the models have a specific regional focus on their inceptions. Much focus is placed on how the models capture the soil moisture signal. We find that there is agreement on seasonal patterns between the models and observations with a tolerable level of model uncertainty.

Data were used to study the wavelength-dependent changes of solar radiation at Earth's surface and to validate parameterizations of solar limb darkening (LD), which describes the change of the Sun's brightness between its center and its edge. The study highlights the importance of the LD effect when calculating total ozone and aerosol optical depth during an eclipse.

Zeldis〈br〉 Biogeosciences Discuss., https//doi.org/10.5194/bg-2018-436,2018〈br〉 〈b〉Manuscript under review for BG〈/b〉 (discussion: open, 0 comments)〈br〉 Globally, we add carbon to the atmosphere from fossil fuels and deforestation, balanced by ocean uptake and atmospheric increase. The difference is a residual sink equated to plant uptake. But this omits cement carbonation and pools of plastic, bitumen, wood, landfills and lakes, and transport by wind erosion, volatile C compounds and river transport. This reduces the residual sink from 3.6 to 2.1 GtC yr〈sup〉−1〈/sup〉 with important implications for natural feedbacks to amplify or negate human C emissions.

We highlight that such technical solutions often result in undesired socioeconomic and ecological consequences such as increased downstream flooding risk, changes of groundwater levels and a loss of aquatic and terrestrial biodiversity. We propose a transdisciplinary approach of integrated flood management and green infrastructure instead of reliance on technical protection measures.

The algorithm has been trained on synthetic multi-angle, multi-wavelength measurements of reflectance and polarization, and has been applied to the processing of one year of POLDER-3 data. Comparisons of the retrieved cloud properties with Moderate resolution Imaging Spectroradiometer (MODIS) products show negative biases around −2 in retrieved cloud optical thicknesses (COTs) and between −1 and −2 μm in retrieved cloud effective radii. Comparisons with existing POLDER-3 datasets suggest that the proposed scheme may have enhanced capabilities for cloud effective radius retrieval at least over land. An additional feature of the presented algorithm is that it provides COT and effective radius retrievals at the native POLDER-3 Level 1B pixel level.〈/p〉

Our results showed that different representations of C–N coupling processes lead to divergent effects on plant production, C residence time, and thus the ecosystem C storage capacity. Identifying those effects can help us to improve the N limitation assumptions employed in terrestrial ecosystem models.

We identified the spatial pattern of soil loss tolerance in karst area, found RUSLE overestimated soil erosion in karst area and proposed an idea for evaluating soil erosion in karst.

We find that vertically migrating phytoplankton, which traverse ~ 100–150 m in the upper ocean over days to acquire nutrients from waters at depth and return to the surface for photosynthesis, likely explain the observed anomalies and help sustain surface ocean productivity and the biological pump throughout the annual cycle in the subtropical ocean.

Much focus is placed on how the models capture the soil moisture signal. We find that there is agreement on seasonal patterns between the models and observations with a tolerable level of model uncertainty.

Maps of saturated water content, field capacity and wilting point are interpreted for a 5775 km〈sup〉2〈/sup〉 catchment at 100 m resolution. Advantages and disadvantages of the two methods are discussed. Absolute difference in soil water retention values are less than 0.025 cm〈sup〉3〈/sup〉 cm〈sup〉−3〈/sup〉 between maps derived with indirect and direct methods for 65–86 % of the catchment.

Different behavior of traditional approaches used for quantifying Whitecapping dissipation under different wave conditions has always been a challenge to choose the most appropriate approach for a given area. The present paper examines the performance of two popular Whitecapping approaches incorporated in SWAN during the winter storms along the U.S East Coast.

This correction has not been evaluated for the soil gas environment where gas transport processes are important.

We also propose a new solution that accounts for soil gas transport processes.

However, by employing high resolution model simulations we find that the effect of short-term aerosol perturbations on Arctic MPCs is efficiently attenuated with time. A substantial fraction of the aerosol is transported out of the boundary layer, which appears to inhibit any long-term impact of time-limited pollution events on Arctic MPCs.

This method has been demonstrated in the Alps and it has been found to reconstruct small-scale precipitation distribution. It can be employed in a number of applications, including the analysis of extreme events and their statistics and hydrometeorological hazards.

Earth Syst.

We show that stochastic hydrogeology's blind spot is in focusing on risk while ignoring uncertainty, to the detriment of its potential clients. The imbalance between the treatments of risk and uncertainty is shown to be common to multiple disciplines.

Here, this technique was applied in airborne measurements, where it was found that majority of atmospheric ice particles have features that significantly change the way ice particles interact with solar light. The microscopic features make ice-containing clouds more reflective than previously thought, which could have consequences for predicting our climate.

Climate and weather models often assume constant vegetation parameters because good measurements are missing. We used affordable accelerometers to measure tree sway of 19 trees in the Amazon rainforest. We show that trees respond very differently to the same weather conditions, which means that vegetation parameters are dynamic. With our measurements trees can be accounted for more realistically, improving climate and weather models.

Our results show that this unpredictability is similar to how infrequent avalanches occur in a sandpile. Transport events are similar in size but become more infrequent and erratic as the river transports less and less sediment.
