The new product [ID: LSA-311] will cover the full MSG disk instead of the four geographical regions (Europe, North Africa, South Africa and South America) covered by the current product [ID: LSA-301]. In the new product, the main improvements to the Evapotranspiration algorithm concern mostly the input data, with a reinforced use of satellite data.

Vegetation information is now provided by LSA SAF MSG LAI (Leaf Area Index) and FVC (Fraction of Vegetation Cover) and updated on a daily basis, and soil moisture information is derived from two complementary sources: H SAF SM-DAS-2 (Soil Moisture Profile Index in the roots region retrieved by surface wetness scatterometer assimilation method) and LSA SAF MSG LST (Land Surface Temperature) products.
