As one of the projects of 211 Program at Ocean University of China, the NOAA/SeaWiFS Satellite Ground Station—TeraScan Desktop System developed by SeaSpace Corporation of USA was established. The NOAA (National Oceanic Atmospheric Administrator) Polar Orbiter Satellites data and SeaStar/SeaWiFS (Sea-viewing Wide Field of view Sensor) data have been received. The objective of the Ground Station is to promote application of ocean remote sensing and multidisciplinary research. The satellite products, e. g., sea surface temperature (SST) have been provided to users.To investigate the accuracy of the NOAA/AVHRR SST product , the processing of NOAA/AVHRR SST by TeraScan system is analyzedo The parameters of TeraScan system are adjusted to retrieve the SST in the region (10° N-50° N, 105° E—145° E) in 2004. The in-situ data from NEAR-GOOS database are used to validate the NOAA/AVHRR SST product .The results show that the bias is -0.29 ℃, and the standard deviation is 0.87 ℃. The sources of error are analyzed .Finally, to improve the accuracy, statistical regression of the matchups in the northwest Pacific Ocean is done .The accuracy of SST derived by regional algorithms is improved.For easy and rapid access of the satellite products, an efficient Web system is developed. It provides functions of browse, query and distribution online of the satellite data. In this thesis the configuration of software and hardware is described .Then selection of web techniques is discussed. System architecture and detailed design are also discussed, such as data ordering, browse and database design .Thesatellite data can be processed and provided to users automatically and rapidly . Thus much time cost and manpower can be saved.
