✍ The findings offer essential insights for enhancing drought prediction and ecosystem management—calling for integrated models that account for both soil moisture and atmospheric demand across diverse climates.

🌍 By comparing field observations with datasets like GLEAM, SEVIRI and ERA5-Land, the study validates key mechanisms controlling ET—pointing to the need for models that respond dynamically to both land and atmospheric drivers.

📊 Declines in ET during dry spells can be up to 50%, mirroring substantial reductions in soil moisture. These dramatic shifts underscore how sensitive water exchange is to drought stress.

☔ In contrast, during wet or non-limited periods, ET is more controlled by atmospheric demand (i.e. VPD) than soil moisture, highlighting a shift in dominant drivers across conditions.

🌱 Using remote sensing, models and in-situ flux tower data, the authors show that during drought years ET dramatically decreases due to dropping soil moisture (SM) and rising vapor pressure deficit (VPD).

➡️ By decoupling roughness from vegetation effects, the new framework provides a stronger geophysical basis for SMOS products and offers a transferable approach for future missions such as SMAP and the upcoming Copernicus CIMR.

🌱 This calibration improves the accuracy of soil moisture estimates when evaluated against ground networks and model simulations (ECMWF), while also enhancing the spatial and temporal consistency of vegetation optical depth (L-VOD) with reference biomass and vegetation indices.

📊 The study replaces empirical approximations with a machine learning model trained on soil and terrain properties, producing a physically based global map of roughness that better captures surface heterogeneity.

🔍 Even high-performing flood detection models trained on single datasets often fail when applied to new regions or different sensor conditions. However, we demonstrate that multi-dataset training strategies significantly enhance model robustness and generalization capabilities.
