The utility of evapotranspiration (ET) maps has been demonstrated in a variety of applications, ranging from water rights management, through drought and food shortage monitoring, to more efficient use of land and water in agriculture and crop stress assessment. The objective of Sentinels for Evapotranspiration project is to leverage the operational capabilities of the Sentinel constellation of satellites to address the need of the agricultural and scientific communities for accurate and timely estimates of evapotranspiration derived at different spatial scales, including at local/field scale. In this context this research project will lead to the development of an open-source software application for modelling of instantaneous evapotranspiration at high (tens of meters) and medium (1 km) spatial resolutions with the synergistic use of observations coming from Sentinel-3 (medium resolution thermal and optical)and Sentinel-2 (high resolution optical) satellites. This objective will be achieved through: 1) Reviewing of existing methodologiesfor estimation of ET and for bridging the spatial gap between Sentinel-2 and Sentinel-3 observations; 2) Prototyping and benchmarking the most promising approaches and evaluating the outputs in a number of ecosystems; 3) Fully implementing the best performing approach as an open-source software application.
