|CMACast is a newly established DVB-S2 standard satellite data broadcast system of China Meteorological Administration. It is maintained by the National Meteorological Information Centre and works as a major component of CMA’s national meteorological data dissemination system. More than 2400 subordinate agencies and local offices of CMA use this system to receive real-time observation data and products for weather forecast relevant services every day. It is also the most effective way for common user communities in China to obtain different kinds of meteorological data and products from CMA.
CMACast is also a major component of WMO IGDDS and GEONETCast systems. FENGYUNCast was integrated into GEONETCast in 2007 and has been operating as a Regional GEONETCast Network Centre (GNC) since then. CMACast has replaced FENGYUNCast as China’s contribution to GEONETCast. With enlarged bandwidth, improved user and data management mechanisms and enriched data contents, CMACast has achieved the ability to offer all services within the framework of GEONETCast and will provide much better services to users in Asia Pacific Region.
