Abstract:

The development of human society is inextricably linked with meteorology. Observation from meteorological satellite is an important means of meteorological forecasting. Meteorological satellite can be in polar orbits and geostationary orbit. Radiometer imager is typically the core payloads of meteorological satellite and makes use of the multi-spectra results to carry out meteorological and climate forecasts. This article focuses on the performance and technical characteristics of the China’s newly developed and launched second-generation geostationary meteorological satellite FY-4 radiometer imager, and introducs the application of its data products in satellite meteorology.

Key words: meteorological satellite, satellite meteorology, radiometer imager, spectral band, meteorological product
