The impact of NOAA satellite sounding data on PRC's weather prediction model has been investigated using both 1979 FGGE and December 1987 datasets. Two experiments, NOSAT and SAT were conducted. Seven areas deemed to have adequate conventional data for definition of ``truth,'' were chosen to compute the verification statistics. The impact of satellite data was then assessed by changes in S1 skill score and root mean square errors for 24 and 48 h forecasts of sea level pressures and 500 mb height. A positive impact on rms errors of up to 11.5% was observed over land for SLP and 8% over ocean for 500 mb height for forecast period of 48 h. Some areas, however, show little or no improvement.
