Abstract. Germany's 2018–2020 consecutive drought events resulted in multiple sectors – including agriculture, forestry, water management, energy production, and transport being impacted. High-resolution information systems are key to preparedness for such extreme events. This study evaluates the new setup of one-kilometer German monitor (GDM), which is based on daily soil moisture (SM) simulations from mesoscale hydrological model (mHM). The simulated SM compared against a set diverse...
Abstract Eddy covariance sites are ideally suited for the study of extreme events on ecosystems as they allow exchange trace gases and energy fluxes between lower atmosphere to be directly measured a continuous basis. However, standardized definitions hydroclimatic extremes needed render studies comparable across sites. This requires longer datasets than available from on-site measurements in order capture full range climatic variability. We present dataset drought indices based...
Abstract Central Europe, including Germany, has faced exceptional multi-year terrestrial water storage (TWS) deficits since 2018, negatively impacting various sectors such as forestry, energy production, and drinking supply. Currently, the understanding of recovery dynamics behind extreme events is limited, which hampers accurate management decisions. We used a simulation mesoscale hydrological model (mHM) over last 257 years (1766–2022) to provide first long-term perspective on TWS deficit...
With climate change, drought events are more likely to occur in Central Europe. The German Drought Monitor is an established tool Germany for assessing the severity of soil moisture events. Based on simulations with mesoscale hydrological model (mHM), it categorizes probability occurrence current dryness compared a historical reference period. In this model, potential access and uptake water by roots vegetation static time determined root fraction each layer. Field estimates suggest that...
Soil moisture (SM) infiltration is crucial in hydrological modeling, as it significantly influences runoff, groundwater recharge, and evapotranspiration. This study compares two widely used approaches for modeling SM mesoscale hydrology: the one-dimensional Richards equation (1-D RE), which controls vertical flux exchange but complex nonlinear, capacity (IC) scheme, simpler only allows downward movement of SM. The challenge implementing RE lies determining effective parameters at targeted...
Geothermal waters often are enriched in trace metal(loid)s, such as arsenic, antimony, molybdenum, and tungsten. The presence of sulfide can lead to the formation thiolated anions; however, their contributions total element concentrations typically remain unknown because nonsuitable sample stabilization chromatographic separation methods convert them oxyanions. Here, concurrent widespread occurrence thioarsenates, thiomolybdates, thiotungstates, thioantimonates, sulfide-rich hot springs from...
Abstract. Adaptation to an increasingly dry regional climate requires spatially explicit information about current and future risks. Existing drought risk studies often rely on expert-weighted composite indicators, while empirical evidence impact-relevant factors is still scarce. The aim of this study investigate what extent hazard vulnerability indicators can explain observed agricultural impacts via data-driven methods. We focus the German federal state Brandenburg, 2013–2022, including...

Climate change is altering the water cycle from global to local scale. The increase in temperatures and changing precipitation patterns intensify not only mean values, but also frequency severity of extreme weather events, leading alterations availability distribution. This study assesses impact climate on flood (maximum annual river discharge) Germany. models ranging different spatial scales will be compared for five largest German catchments outlets (including headwaters). model ensembles...
It is projected that the likelyhood and duration of extreme soil moisture (SM) droughts will increase in Germany under future warming scenarios. Annual precipitation changes are small climate change with increases winter decreasing summer for some parts Germany. Generally, ensemble spread signal large. Furthermore, impacts SM depend largely on volume evaluated. We identified a gradient stronger drying shallow compared to deeper global warming, leading different effects shallow-rooted...

Global warming is altering soil moisture (SM) droughts in Europe with a strong drying trend projected the Mediterranean and wetting trends Scandinavia. Central Europe, including Germany, lies transitional zone showing weaker diverging change signals exposing region to uncertainties. To analyse SM drought changes associated uncertainties we utilize large multi-model ensemble of 57 bias-adjusted spatially disaggregated regional climate model simulations run hydrologic mHM at high spatial...

The climate crisis leads to a change in forest tree species distributions, favouring most likely heat and drought tolerant species. As consequence, many sites across Europe will become unsuitable for sensitive combination of conservation goals Natura2000 habitat types lead severe conflicts forestry. concept “no deterioration” article 6 the Habitats Directive supports static prevalent flora fauna. In those areas forestry is oriented towards natural types. Especially with...
