High-resolution (1 km) all-sky net radiation over Europe enabled by the merging of land surface temperature retrievals f...
Surface net radiation (SNR) is a vital input for many land surface and hydrological models. However, most of the current remote sensing datasets of SNR come mostly at coarse resolutions or have large gaps due to cloud cover that hinder their use as input in models. Here, we present a downscaled and continuous daily SNR product across Europe for 201...
A new post‐hoc method to reduce the energy imbalance in eddy covariance measurements
Latent and sensible heat flux observations are essential for understanding land-atmosphere interactions. Measurements from the eddy covariance technique are widely used but suffer from systematic energy imbalance problems, partly due to missing large eddies from sub-mesoscale transport. Because available energy drives the development of large eddie...
A robust model for diagnosing water stress of winter wheat by combining UAV multispectral and thermal remote sensing
Diagnosing water conditions timely and accurately is crucial for seasonal irrigation scheduling in crop production. The purpose of this study was to establish robust water deficit models of winter wheat in different growing seasons by combining unmanned aerial vehicle (UAV) multispectral and thermal images. In 2021 and 2022, a water deficit field e...

Identical hierarchy of physical drought types for climate change signals and uncertainty
Climate change may have different impacts on different types of drought through its influence on the mechanisms of the propagation of a precipitation lack into a hydrological or agricultural drought. The involvement of additional processes in runoff and soil moisture modeling potentially leads to discrepancies in the projection uncertainties and si...
Global dryland aridity changes indicated by atmospheric, hydrological, and vegetation observations at meteorological sta...
In the context of global warming, an increase in atmospheric aridity and global dryland expansion under the future climate has been expected in previous studies. However, this conflicts with observed greening over drylands and the insignificant increase in hydrological and ecological aridity from the ecohydrology perspective. Combining climatic, hy...
Modeling the effects of improved irrigation methods in a groundwater system : a case study from the Amu Darya Delta, Uzb...
Suitable groundwater levels have a significant influence on vegetation growth, regional salinization, and ecological sustainability. Because of long-term low-efficiency irrigation methods and water canals, the stream flows vanish before reaching the South Aral Sea, leading to a rapid shrinkage of lake coverage since 1960. Meanwhile, the groundwater...
Bridging scales : an approach to evaluate the temporal patterns of global transpiration products using tree‐scale sap fl...
Transpiration is a key process driving energy, water and thus carbon dynamics. Global transpiration products are fundamental for understanding and predicting vegetation processes. However, validation of these transpiration products is limited, mainly due to lack of suitable data sets. We propose a method to use SAPFLUXNET, the first quality-control...
Incorporating plant access to groundwater in existing global, satellite-based evaporation estimates
Groundwater is an important water source for evaporation, especially during dry conditions. Despite this recognition, plant access to groundwater is often neglected in global evaporation models. This study proposes a new, conceptual approach to incorporate plant access to groundwater in existing global evaporation models, and analyses the groundwat...
