Abstract

This paper presents the comparison of the estimation of spatial rainfall from the dual polarization c-band radar over the central part of Thailand, radar orbital radar, with rainfall data from meteorological stations. In this study, the data were validated (QC) by eliminating non-rain data, and Inverse Distance Weighted (IDW), Kriging and Trend, respectively, were used to determine the amount of precipitation, compared with the rainfall obtained from the meteorological stations. Statistical analysis was performed. The results show that the Kriging method is the best estimation method, giving a good correlation coefficient, and the accuracy of the estimation of rainfall is better than the Inverse Distance Weighted (IDW) and Trend, respectively.
