Author Affiliations +
Retrieval of atmospheric profiles from the vertical atmospheric sounding suite aboard the Chinese FY-3A satellite has been investigated. A statistical retrieval approach is used to generate atmospheric temperature and moisture profiles. The statistical retrieval method is only applied to the clear-sky simulated radiances, achieving good retrieval accuracy. For example, in the simulated experiment, the retrieved atmospheric temperature and moisture profiles show good agreement with independent atmospheric samples. The RMS is about 1.2K on the average for temperature profile. The RMS is large for the near surface levels. The RMS of moisture profile is approximately 11%. The temperature and moisture fields agree well with the NWP analyses of NCEP.
