Computer tomographic sounder with hyper-spectral resolution for OH radicals in the upper and middle atmosphere
OH radicals in the upper and middle atmosphere are important oxidants and play an important role in atmospheric photochemistry. Current space-based payload can only obtain profile information. In view of the inhomogeneity of atmospheric two-dimensional distribution field, a hyper-spectral OH radical tomography detection scheme based on one-dimensional imaging spatial heterodyne spectroscopy is proposed. In this paper, the basic principle of SHS is introduced. Then it introduces the detection mode of computer chromatography and the principle of atmospheric inversion. Finally, it introduces the design of OH chromatography sounder based on the principle of SHS technology. In order to verify the effectiveness of the design, the data simulation is carried out.
