Study of Ozone Retrieval with MODIS Data based on Infrared Spectrum Match Method

摘要

MODIS, a moderate-resolution imaging spectroradiometer instrument on board EOS-AM1 and PM1, has 36 spectral bands amongst which only 9.6 μm band sensitively traces atmospheric ozone. To produce total ozone inversion, one requirement is via temperature and pressure profiles, a popular requirement of mass-calculation which could now be argued not a literally convenient idea. Thus, in this paper I try my hand at a new method through firstly, overall bands' correlative statistics and analysis based on MODIS high-precision data source in spectral radiation, to materialize "similar TRIPLET" spectral data combination method. Then it comes to us a need to attain a solid cooperative optimization, and thirdly with forgoing output a process is introduced here of spectrum differential calculation leading to final total ozone inversion.
