With the development of the GPS satellite network, an opportunity now exists to acquire valuable precise temperature, pressure, and humidity data using radio occultation. It gives an overview of the Radio Occultation Data Processing in Shanghai Astronomical Observatory (SHAO). More than 2,700 CHAMP neutral atmosphere soundings were processed at SHAO in the period August 1st, 2002 to August 17th, 2002. The retrieved atmospheric profiles from CHAMP data were compared with the European Centre for Medium-range Weather Forecasts (ECMWF) analysis data. It also presents the statistic and analysis results by the comparisons among these datasets, and discusses the data quality of CHAMP radio occultation data. The computational results fairly indicate the potential of GPS occultation data which might become an extremely valuable data source for the numerical weather prediction (NWP) and long-term monitoring of the earth's climate.
