摘要
Ground-based observation of atmospheric microwave noise may be used to get atmospheric temperature-humidity profile and parameters of cloud and rain. From September to October 1981, the experiment of remote sensing on atmosphere was carried out at Peking University with 5 mm—1.35 cm band 4-channel radiometers. In this note, we present and discuss the experimental results from 8 mm to 1.35 cm radiometers of remote sensing atmospheric water vapor content and the characteristics of absorption in λ=1.35 cm water vapor band and λ=8 mm window band. In these bands, the microwave absorption of atmosphere is small, much smaller
