应用FY-3A/MWHS资料反演太平洋海域晴空大气湿度廓线
RETRIEVAL OF CLEAR SKY MOISTURE PROFILES IN THE PACIFIC USING MEASUREMENTS OF MWHS FROM FY-3A SATELLITE
摘要
Abstract
An improved Smith iterative method, which generally applies to microwave bands, is described. The moisture profiles retrieved from the brightness temperature data of microwave humidity sounder onboard FY-3A satellite, pertaining to clear sky, are shown over North-West Pacific by using a vector-discrete ordination radiative transfer model. The retrieved profiles are compared with those from MODIS products, and the results of single point show that they are in good agreement with the results for lower layers. The distribution of retrieved humidity at 500hpa is basically consistent with the actual situation, and the values are lower than that of the MODIS products. Compared with MODIS products, RMS is within 5.76g/kg at every single level separately.关键词
