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.
