The project relies on weather data derived from meteorological reanalysis models and weather satellite images. The Antarctic ozone hole is mapped from weather satellite data. SSF has developed flight and ground software for the European MetOp weather satellite programmes. AO-5 was launched piggyback with ITOS-1 (TIROS-M weather satellite). Vanguard 2 was the first weather satellite. Weather satellite systems provide information about terrestrial weather. The launch of the weather satellite GMS-3 was delayed by this typhoon's passage nearby Japan. The third, Vehicle 178, launched on May 3, 1986 with a GOES weather satellite. The Richmond Campus' CSTARS provides RSMAS with a near-real-time weather satellite downlink. The Meteosat-2 geostationary weather satellite began operationally to supply imagery data on 16 August 1981. It is used aboard polar-orbiting, near-Earth weather satellite programs such as MetOp and NPOESS. Unbeknownst to many, the U.S. military services were also starting up a weather satellite program. A low-resolution image of the explosion was captured by the weather satellite Meteosat 8. GOES weather satellite communications were interrupted causing weather images to be lost. Meteosat 8 is a weather satellite, also known as MSG 1.
