Channel selection and analysis of geostationary interferometric sub-millimeter sounder

Geostationary sub-millimeter atmospheric sounder based on interferometric technology is the newest field of microwave remote sensing. Equipped with a sub-millimeter atmospheric remote sensing instruments on the geostationary orbit meteorological satellite platform will increase the frequency of observations at the same time, improve the cloud detection capability. The current polar-orbiting meteorological satellite observation system ensures that only six hours of observation period, unable to typhoons and other fast-changing weather systems for real-time observation. Geostationary sub-millimeter sounder [1-3] has the characteristics of working all-weather, all-time, large coverage and real-time. The whole process of dynamic changes in the weather can be observed, providing high temporal resolution observation data for numerical weather prediction and immediate short-term forecasting. In the paper, the content will mainly include channel Selection and analysis of geostationary interferometric sub-millimeter sounder.
