Introduction:

The development of open-access Earth Observation databases, especially for information related to actual evapotranspiration, is urgently needed. Scientists from IWMI, UNESCO, Delft Technical University, and the EROS Centre explain how Earth Observation data in the public domain can be used to estimate net water production (rainfall (P) > evapotranspiration (ET)) and net water consumption (ET > P) of Nile Basin agro-ecosystems. Measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS), Second Generation Meteosat (MSG), Tropical Rainfall Measurement Mission (TRMM) and various altimeters are used. The paper is part of the Remote Sensing Special Issue 'Earth Observation for Water Resource Management in Africa ' and the fluxes, flows and storage changes presented form the basis for a global framework for describing monthly and annual water accounts in ungauged river basins.
