The Atmospheric Transmissivity Measurement in Infrared Window Region

This report mainly introduces the theory and facility for measuring solar infrared spectrum of window region. It also gives the method for calculating the atmospheric transmissivity within the range of 2390cm-1 to 3470cm-1 and 750cm-1 to 1300cm-1. The analysis results show that the data is helpful to the choice of infrared channels of remote sensing instruments of meteorological satellite, it is also useful to the retrieval of satellite data and so on.
