The retrievals from the AVHRR/HRPT data sea surface temperature computation software system using the NOAA-7 and NOAA-9 AVHRR data received at Beijing Meteorological Satellite Ground Station during the periods of 17, February and 7, September 1984, and 19-20, August, 14, September and 13-15, October, 1986, respectively, were compared with simultaneous measurements from ships and buoys. The result from these comparisons shows that the averaged root mean sq'uare deviation for the above five periods is about 1.01℃.
