Parameterized Path Radiance Model for Satellite Remote Sensing Application

Qiu, Jinhuan

研究概要:In this study, the path radiance in the homogeneous atmosphere is parameterized by using the least square method and the empirically fitting method, and the radiance in the inhomogeneous atmosphere is expressed as that calculated by the homogeneous model plus some empirical correction. Accuracy of the parameterized path radiance is analyzed through comparing the radiance with that calculated by DISORT in numerical simulations. In the case of the aerosol optical thickness of <0.8, the viewing angle of 0°to 60°, and the cosine of solar zenith angle changing from 1.0 to 0.3, the error of the parameterized path radiance in the homogeneous atmosphere can be less than 10%.0 The error of the correction factor in the parameterization model of the path radiance in the case of the inhomogeneous atmosphere is less than 12.3 0n wide aerosol conditions, including aerosol optical thickness of ≤2.35.
