Overview of the Energy and Water Balance Monitoring System (EWBMS)
EARS is operating receiving facilties for Meteosat/MSG over Africa and the Indian Ocean, and for FengYun-2c over Eastern Asia. Visual and Thermal Infrared Data are received and pre-processed hourly. The data are processed in two lines. The first line generates cloud frequencies at several levels and precipitation data fields based thereon. The second line produces temperature, albedo, radiation, sensible heat and evapotranspiration data. These primary data products are thereafter used to generate user oriented products related to drought, crop yield and river flow.
