Abstract

The vertical profile of raindrop size distribution (DSD) is important for understanding rain formation processes. To improve the accuracy of rainfall intensity observed by precipitation radar and microwave radiometers carried on satellites, the information on the vertical profile of DSD is also important. The purpose of this study is to develop a database of DSD form rainfall (below the melting layer) to snowfall (above the melting layer) for the satellites precipitation retrieval by using a 400MHz wind profiler. A new algorithm is proposed above the melting layer. As a result, in the case of the spectrum peak of air motion is difficult to find from the observed Doppler spectrum above the melting layer, it is possible that DSD can be estimated by the proposed algorithm.
