Tropical Applications of Meteorology using Satellite - (TAMSAT)
The TAMSAT RFE imagery uses TIR images to derive the Cold Cloud Duration (CCD) and rain gauge measurements to infer rain precipitations. The calibration of data is done by using historical timeseries and the approximate horizontal resolution is of 4 km.
These products provide input for hydrological and agrometeorological models as well as climate information e.g. compare the current state of rainfall with previous time periods.
