Abstract The Tibetan Plateau (TP) is a globally important “water tower” that provides water for nearly 40% of the world’s population. This supply function claimed to be threatened by pasture degradation on TP and associated loss regulation functions. However, neither potential large scale changes nor their drivers are known. Here, we analyse trends in high-resolution dataset grassland cover determine interactions among vegetation dynamics, climate change human impacts TP. results reveal have...
Abstract Background The decision of the German federal government to cease lignite mining until 2038 or—if possible—already earlier 2030, will cause manifold transition processes in remaining districts Germany. two largest are located geographically opposite regions: Rhineland western part and Lusatia east As particularly these experience severe changes their socioeconomic as well environmental conditions, has adopted comprehensive economic support measures. However, also altered ecosystem...
Mountain regions worldwide present a pronounced spatiotemporal precipitation variability, which added to scarce monitoring networks limits our understanding of the generation processes involved. To improve clouds and dynamics cross-scale in mountain regions, we analyzed rainfall patterns using satellite cloud products (SCP) Paute basin (900–4200 m a.s.l. 6481 km 2 ) Andes Ecuador. Precipitation models, SCP GIS data, reveal spatial extension three regimes: three-modal (TM) regime across...
Understanding the interaction between energy and water fluxes at atmosphere-surface interface is essential for advancing knowledge of climate dynamics variability. This study evaluates surface (including soil moisture) flux components, alongside air temperature, in global regional model (GCM RCM) simulations  applied NUKLEUS project (funded by German Federal Ministry Education Research, BMBF). The analyses aim to enhance understanding consistency process representation RCMs their...
The Atacama Desert is well known for the high occurrence of large-scale fog (spatial extents: hundreds kilometers) emerging as low stratus (LST) decks over Pacific Ocean. By contrast, small-scale and heterogeneous (hundreds meters) particularly during summers widely unconsidered. However, these events are important local vegetation biological soil crusts (BSC) that distributed in this extreme ecosystem. Consequently, a case study typical oasis Pan de Azúcar National Park was conducted to...
Abstract For next-generation weather and climate numerical models to resolve cities, both higher spatial resolution subgrid parameterizations of urban canopy–atmosphere processes are required. The key is better understand intraurban variability urban–rural differences in atmospheric boundary layer (ABL) dynamics. This includes upwind–downwind effects due cities’ influences on the atmosphere beyond their boundaries. To address these aspects, a network >25 ground-based remote sensing sites...
Tropical forests, spanning wet and dry forest ecosystems, are pivotal in regulating the global carbon cycle climate through dynamic exchanges of energy, water, carbon. These ecosystems influence regional patterns via biogeochemical feedback mechanisms. However, change is altering these processes, with rising temperatures intensifying evaporative demand affecting photosynthetic activity, as indicated by changes net ecosystem exchange (NEE). Vegetation biomass variations further impact...
Evapotranspiration (ET) is a vital component of the hydrological cycle, mediating energy, water, and carbon exchanges on land surfaces atmosphere, which are critical for agricultural water availability. Understanding spatiotemporal variability ET its relationship with atmospheric drivers use/land cover change (LUCC)  crucial assessing environmental impacts regional cycles improving resource management.This study focuses lowlands in eastern Germany. It predominantly region...
Flash droughts pose a serious threat to agriculture due their abrupt onset and rapid intensification. The increasing frequency of such events presents considerable challenges uncertainties for agricultural carbon sequestration, particularly during the growing season. To effectively assess dynamics in agroecosystems under ongoing climate change, it is crucial understand complex interactions among energy, water, fluxes, as well connection vegetation.An open-path eddy-covariance (EC)...
Ammonia (NH3) emissions play a significant role in air quality degradation, biodiversity loss, and human health risks by forming secondary pollutants such as fine particulate matter (PM2.5). This study presents decadal (2013–2022) spatiotemporal analysis of NH3 the lowlands eastern Germany, using data from Infrared Atmospheric Sounding Interferometer (IASI-B) onboard MetOp-B satellite. The region, characterized predominantly agricultural land use (54.71%), offers valuable case for...
Urban planners and engineers rely on historical climate data to design flood protection infrastructure capable of withstanding extreme flooding events, typically associated with a 1% annual exceedance probability (the 100-year flood). This study examines how hourly precipitation extremes are expected evolve rising temperatures these changes will influence urban risks. Specifically, we address the often-overlooked impact short-duration rainfall using new non-stationary temperature-conditional...
Ammonia (NH3) emissions, which are key precursors of fine particulate matter, pose significant environmental challenges. This study investigated the spatiotemporal variations in NH3 emissions across eastern German lowlands from 2013 to 2022 using IASI-B satellite data. Five major Land Cover Classes (LCC) –tree, grassland, cropland, built-up areas, and water bodies– were analyzed. The results showed distinct diurnal variations, with nighttime concentrations exceeding 2.0 × 1016 molecules cm−2...
Abstract Water‐bound nitrogen (N) cycling in temperate terrestrial ecosystems of the Northern Hemisphere is today mainly inorganic because anthropogenic release reactive N to environment. In little‐industrialized and remote areas, contrast, a larger part occurs as dissolved organic (DON). north Andean tropical montane forest Ecuador, cycle changed markedly during 1998–2010 along with increasing deposition reduced soil moisture. The DON concentrations fractional contribution total...

The investigation is based on Geostationary Operational Environmental Satellite-East (GOES-E) satellite imagery (2005–07), images scanning X-band rain radar, data from regular meteorological stations. work was conducted in framework major ecological research program, Research Unit 816, which instruments are installed Rio...
Mesoscale convective systems (MCSs) climatology, the thermodynamic and dynamical variables, teleconnections influencing MCSs development are assessed for Paute basin (PB) in Ecuadorian Andes from 2000 to 2009. The seasonality of occurrence shows a bimodal pattern, with higher during March-April (MA) October-November (ON), analogous regional rainfall seasonality. diurnal cycle clear nocturnal occurrence, especially MA ON periods. Interestingly, despite rainy seasons, monthly size relative...

The RadarNet-Sur is based on three scanning weather units that cover approximately...
Abstract. Climate models are in need of improved constraints for water vapor transport the atmosphere, and tritium can serve as a powerful tracer hydrological cycle. Although general principles distribution transfer processes within between various compartments known, variation on short timescales aspects altitude dependence still under debate. To address questions regarding sources, sinks, processes, sampling individual precipitation events Corte island Corsica Mediterranean Sea was...
Drought is a major factor limiting tree growth and plant vitality. In the Mediterranean region, length intensity of drought stress strongly varies with altitude site conditions. We used electronic dendrometers to analyze response two native pine species precipitation events. The five study sites were located along an elevation gradient on island Corsica (France). Positive stem increment in raw dendrometer measurements was separated into radial swelling/shrinkage order determine which part...
