English Abstract
Rainfall is the dominant forcing factor for most hydrological processes.
Rainfall may be estimated for ungauged areas using Cold Cloud Duration (CCD) Technology.
CCD estimates are based on the cloud top temperature.
Rainfall formation is related to the cloud top temperature and the duration during which the temperature of the cloud was below a threshold level.
There are problems related to point rainfall measurement and their subsequent use in the estimation of a real rainfall in large catchments.
Indeed, the most widespread application of point rainfall records is in the estimation of rainfall in relatively large areas.
The gauging stations are frequently sparsely located.
Point rainfall gauging networks are reducing in capacity with most used facilities in need of repair and maintenance.
CCD rainfall estimation has the advantage of being inherently spatial.
The overall objective this study is to asses the publically available rainfall estimation against the ground information in about ten stations in Sudan.
Regression analysis is used to find the relationship between the observed rainfall and Rainfall estimated from NOAA (RFE).
The model efficiency is obtained by Nash & Sutcliffe (1970).
The result obtained from comparison between estimation rainfalls with the observation one for ten selected gauge stations in Sudan checked a relatively low correlation indicating in most cases the question of less reliability on the NOAA (RFE).
