Abstract

The invention discloses a satellite remote sensing atmospheric ozone profile inversion algorithm, which comprises: 1, carrying out radiation calibration and wavelength calibration by using an ozone monitoring instrument OMI; 2, carrying out radiation transmission model and weighting function calculation; and 3, inverting atmospheric ozone profile information based on an optimal estimation technology algorithm by using the radiation spectrum simulation value and the weighting function parameter calculated in the step 2 after the radiation calibration and the wavelength calibration of the ozonemonitoring instrument OMI are completed. According to the present invention, the algorithm is established by using the OMI ultraviolet radiation spectrum data and selecting the fitting wave bands UV-1and UV-2, and can invert the atmospheric ozone profile information from the earth surface to the 60 km atmosphere based on the optimal estimation technology, wherein the atmospheric ozone profile information comprises the total ozone column concentration, the troposphere ozone column concentration and the stratosphere ozone column concentration, such that the troposphere atmosphere ozone profileis accurately inverted; and the method can be used for analyzing the relationship between atmospheric ozone convective motion, exchange processes, biomass burning and human pollution, and tracking thetemporal and spatial transport of ozone.

Description

technical field [0001] The invention relates to the fields of environmental science and satellite remote sensing technology, in particular to a satellite remote sensing atmospheric ozone profile inversion algorithm. Background technique [0002] Atmospheric ozone accounts for only a few millionths of each component in the air, but it has an important impact on global climate and environmental changes. Since the 1970s, total column ozone concentrations and ozone profiles have been derived from data measured by solar backscattered ultraviolet instruments aboard a series of NASA and NOAA satellites. Due to the low resolution of these instruments, only the (20-25km)-50km ozone vertical profile information and the ozone column concentration results above the cloud height can be retrieved from them. To obtain vertical ozone profile information at lower altitudes, high-resolution hyperspectral instruments are required. Compared with solar backscattering ultraviolet instruments, m...
