[0031] Overview of FY-2C Meteorological Satellite Features
[0032] FY2C is my country's first operational meteorological satellite in geostationary orbit. It was launched by the Long March 3A carrier rocket at 9:20 on October 19, 2004, and is positioned over the equator at 105° east longitude. Table 1 shows the parameters of all five channels of FY2C visible light channel, water vapor channel, split window infrared channel and mid-infrared channel. It is worth mentioning that FY2C has added a mid-infrared band (3.5μm-4.0μm), which can be applied to the observation of forest fires, grassland fires, sea fog, land fog, sandstorms, etc.
