基于地球红外背景模拟的水云大气影响初步分析
Preliminary Analysis of the Water-Cloud Atmosphere's Effect Based on Earth-Background Infrared Simulation
摘要
Abstract
To improve the earth-background radiation model, path transmittance of water-cloud atmosphere and compo?nents of earth-background radiance in 4 target areas, based on real surface type and climate, were calculated. Through rel?ative change ratio, the identification of water-clouds IR picture and the influence of aerosol and atmospheric models over the solar and atmospheric scattered radiation were analyzed. The results showed that water-clouds exert significant influ?ence on the process. Radiance below the clouds were rapidly attenuated while the scattered radiance were greatly en?hanced. In the same area, cumulus causesd the biggest change to observing-path radiance. Besides, scattered radiance dif?fered respectively from each other in different areas, which proved aerosol and atmospheric model are indispensible factors for simulating water-clouds in earth-background radiance. The calculation and analysis results could provide data and technology support for generating water-clouds' IR picture in earth-background radiation simulation.关键词
