Important Notice: We are pleased to announce the release of data from the Operational Simplified Surface Energy Balance (SSEBop) version 6 model for global actual evapotranspiration (ETa) estimation. SSEBop v6 uses the Visible Infrared Imaging Radiometer Suite (VIIRS) thermal imagery as the main input and is parameterized using the novel Forcing and Normalizing Operation (FANO) algorithm to establish the wet-bulb boundary condition, allowing a robust mapping of the spatiotemporal dynamics of ETa in all landscapes and all seasons regardless of vegetation cover density. A recent evaluation of the global ETa product shows promising performance of ETa Anomaly for drought monitoring purposes while water budget studies, requiring absolute magnitudes, may need to apply a local/region-specific bias correction procedure.
SSEBop v6 is available at dekadal, monthly, and yearly aggregations (February 2012-Present).
