NSMC carries out activities of theoretical and experimental researches on radiation transmission in the atmosphere, the algorithm for meteorological satellite data processing as well as the application of meteorological satellite data. These researches have in turn supported the development of NSMC, promoted the meteorological satellite data application in China and also the international cooperation. The main functions of NSMC include:
NSMC has facilities of satellite meteorology research, system design, computer system, satellite, operation control, and operational and service system support. The three ground stations of Beijing, Guangzhou, Urumqi are also under the supervision of NSMC. The ground system consisted of three receiving stations and a data processing center has fulfilled the tasks of data receiving and processing. By using the ground system, NSMC receives and processes meteorological satellite data from both Chinese and foreign satellites. These data have played an important role in the fields of weather forecasting, natural disaster monitoring and national economy. To help weather stations and various users to receive and use the meteorological satellite data directly, the NSMC is engaged in the researches of satellite data receiving and communication techniques and manufacture of both hardware and software for various meteorological satellite data applications systems.
Meteorological satellite operators coordinate their activities on a global scale through participation in the Coordination Group for Meteorological Satellites (CGMS) which meets once a year. The China Meteorological Administration has participated in the CGMS since 1989. Other members include Japan, Russia, the USA and EUMETSAT. The World Meteorological Organization is also a member, representing the key user community.
