As the developing of space technique, the meteorological satellite and its instruments have experienced great improvement. Right now, China, Europe and United States are operating their own polar and geostationary meteorological satellites,and Japan, South Korea have also established national geo-stationary meteorological satellite system. Compared with its early stage, today's meteorological satellite improved enormously, especially in its spatial, temporal and spectral resolution as well as spectral coverage. Meanwhile, satellite data application has also developed tremendously, taking into account the maturity of data useness as well as the domination of the use of quantitative data. In this paper, the status of current meteorological satellite and the capacity of its payloads are reviewed, and then the application of satellite data in the field of weather analysis, climate and environment disaster monitoring is also described.
