Foundation remote sensing atmospheric hydrochlorofluorocarbon HCFC-142b concentration vertical distribution inversion algorithm

Abstract

The invention relates to the technical field of atmospheric measurement and inversion, in particular to a ground-based remote sensing atmospheric hydrochlorofluorocarbon HCFC-142b concentration vertical distribution inversion algorithm. According to the technical scheme, the method comprises the steps that a foundation high-resolution Fourier transform infrared spectrometer is adopted, a solar mid-infrared absorption spectrum with the wave band of 700-1350 cm <-1 > and the spectral resolution of 0.005 cm <-1 > is obtained, and meanwhile the atmospheric temperature, the atmospheric pressure and the surface meteorological parameters related to water vapor are synchronously collected. According to the ground-based remote sensing atmospheric hydrochlorofluorocarbon HCFC-142b concentration vertical distribution inversion algorithm, a priori profile is constructed through high-resolution spectrometer acquisition, data preprocessing and multi-source data fusion, a forward model is established by considering atmospheric physical characteristics, and inversion is constrained by an advanced regularization algorithm, so that the inversion precision and accuracy are effectively improved; and the adaptability and reliability of the algorithm to the atmosphere complex condition are enhanced.
