Development status and trends of atmospheric trace gas remote sensing instruments

The development of atmospheric trace gas detection technology is elaborated. The design concepts, working principles and apparatus functions, working modes, spectrum setting and the main technical indicators of several kinds of advanced atmospheric trace gas remote sensing instruments are introduced in detail. Then, the present situation of the atmospheric trace gas detection apparatus on remote sensing satellite in China is discussed, and the working models, spectral set and other technical indicators for two typical remote sensing instruments are given. Finally, the future development direction of spaceborne atmosphere trace gas detection instrument is pointed out, which involves the improvements of the spectral resolution, spatial resolution sense- tivity and calibration accuracy of the instrument and the development of active remote sensing technology. These provide a reference for the development of our country＇s satellite atmospheric trace gas detection appara- tus.
