Abstract The evaporative fraction of the surface energy balance has been favoured as a tool to describe the energy partitioning during daytime. It is shown that the evaporative fraction behaves temporally stable under heterogeneous terrain conditions in the Echival Field Experiment in Desertification-Threatened Areas (EFEDA). The evaporative fraction has been calculated by means of data retrieved from geostationary satellites using the SEBAL model. The overall attainable accuracy of the evaporative fraction changes with spatial resolution in relation to the correlation length of the land surface processes.
