IMPROVING OF WINTER QUANTITATIVE PRECIPITATION ESTIMATION USING XRAIN

Abstract

 In recent years, high-precision rainfall observation using operational polarimetric radar data has been realized. On the other hand, there are various problems in the case of classifying solid precipitation particles, and observation accuracy is not high enough. Therefore, we have developed a winter precipitation estimation method using hydrometeor classification method. As a result of comparison with the ground observation results, it was confirmed that the estimation accuracy of the particle type on the ground is about 70%. In addition, it was possible to identify the radar constant(B, β) for each particle in the Z-R relationship.
