摘要：

The study analysed monthly satellite RFE (rainfall estimates) from NOAA (National Atmospheric and Oceanic Administration) and monthly rainfall records (January 1996-December 2006) collected from weather stations by NMA (National Meteorological Agency of Ethiopia) Can the RIFE data be used reliably to analyse seasonal rainfall variability? After doing spatio-temporal analyses of the two datasets. a significant correlation during the important rainy seasons. summer and spring and a low correlation during winter was shown In conclusion the RFE images can be used reliably for early warning systems in the country and to empower decision makers on the consequences caused by the changes in the magnitude, timing. duration, and frequency of rainfall deficits oil different spatial and temporal scales (C) 2009 Elsevier B V All rights reserved
