Rainfall from June 1995 onwards was downloaded for 10-day (dekad) periods from FEWS-ADDS.
To estimate rainfall, FEWS uses satellite information of cold cloud duration (CCD) from the
Geostationary Operational Environment Satellite (GOES). The CCD estimate is adjusted using available rain gauge data,
topography, relative humidity, wind direction and terrain slope.
The FEWS data was used to calculate annual rainfall 1996 - 2004.
