Abstract :
A method to correct spaceborne rain radar measurement for non-uniform beam filling (NUBF) is studied using a shipborne radar data set over the tropical Pacific. Statistical analyses are made on spatial variabilities of rain rate. The result is reflected in estimating the variability in a radar IFOV which is then used to obtain a NUBF correction factor. Results indicate the usefulness of this method for reducing bias error in rain rate estimation
