FAO RFE is a new independent method to estimate the rainfall amount, particularly,
for certain regions where the coverage of the weather stations is scarce.
FAO RFE is based on the Meteosat Second Generation IR channel combined with data coming
from ECMWF global forecast model and EUMETSAT MPE. A local calibration is
performed using the ground gauges, directly received as SYNOP messages and
after a data validation ( method presentation - 1896 KB).
