SEVIRI derived ET data sets

There are two relevant SEVIRI derived ET data sets distributed by the EUMETSAT Satellite Application Facility on Land Surface Analysis (LSA SAF) (https://landsaf.ipma.pt/en/data/; last access: 1 December 2021); (i) SEVIRI- actual ET (SEVIRI-ET_a) that accounts for the water evaporated from the soil surface, vegetation canopy and water bodies, and (ii) SEVIRI- ‎reference ET (SEVIRI-ET₀) that accounts for the (local) atmospheric demand and corresponds to the ET from a hypothetical well-watered green grass having 12 cm height and 0.23 albedo under the given down-welling short-wave radiation (Allen et al., 1998). These data sets are being provided in near real-time through the LSA SAF operational system and we used them in the GEOEssential project for water stress workflow development.
