Publikováno v: Proceedings of the International Association of Hydrological Sciences, Vol 380, Pp 17-22 (2018)

EvapoTranspiration (ET) is an important component of the water cycle, especially in semi-arid lands. Its quantification is crucial for a sustainable management of scarce water resources. A way to quantify ET is to exploit the available surface temper

Publikováno v: Hydrology and Earth System Sciences, Vol 22, Pp 2187-2209 (2018)

In semiarid areas, agricultural production is restricted by water availability; hence, efficient agricultural water management is a major issue. The design of tools providing regional estimates of evapotranspiration (ET), one of the most relevant

Publikováno v: Hydrology and Earth System Sciences, Vol 21, Pp 5693-5708 (2017)

Agricultural landscapes are often constituted by a patchwork of crop fields whose seasonal evolution is dependent on specific crop rotation patterns and phenologies. This temporal and spatial heterogeneity affects surface hydrometeorological proce
