 This study uses high-resolution satellite data to model growing season dynamics and estimate sensible heat flux in desert, and Oasis ecosystems in the small Arles Sea Basin, SASB. The results show a significant improvement in flux estimations compared to the original surface energy balance algorithm for land, SEABLE, revealing land use contributions to evapotranspiration variability and providing insights into desert, and Oasis water use patterns. These findings suggest the potential for continuous daily ET monitoring, which could improve water resources decision support in complex dry land environments.
