The first map indicates the total rainfall amount from 1st May
to 30th June. Data is extracted from FAO field reports and the RainFall Estimate
(RFE) Satellite Imagery as produced by the NOAA/USGS/FEWS/USAID project. The
RFE images are obtained by interpolating various parameters recorded on the
ground and obtained through remote sensing measurements such as: rainfall,
relative humidity, wind speed, elevation, cold cloud temperatures.
The map below shows the estimated planting time (opportunity) as defined by dekad (10-day) satisfying the following requisites: during the first dekad, 25 mm of rainfall should be measured and a total rainfall of at least 20 mm should be recorded during the two next dekads. Data used for this analysis are from FAO field reports and RFE imagery.
