The paper presents a new approach for the satellite retrieval of atmospheric humidity form TIROS-N Operational Vertical Sounder (TOVS) observations with 6-hour numerical forecasts from the National Meteorological Center (NMC) as the first guess of the Simultaneous Physical Retrieval Model (SPRM). It is shown that the RMS error of SPRM retrievals is about 20%, and the results for the summer time is slightly better than those for the winter time. As compared to the first guess. The SPRM retrievals have greatly improved especially for the lower level (1000 hPa) and higher levels (above 500 hPa). Also, the SPRM results are much better (about 10%) than those from the statistic regression method. This research will lay the foundation for establishment of a cycle system of interaction among the satellite retrieval, data assimilation and numerical prediction.
