Abstract

Based on the analysis of results of radiative transfer simulation

a method for ground-based infrared remote sensing of cloud based on height is proposed according to the monotonic relationship between Cloud Base Height（CBH） and the downwelling infrared radiance.A preliminary comparison experiment is conducted with cloud base height measured by laser ceilometers.The results show high accuracy of CBH of middle and low cloud determined according to the proposed method with an average error of 107 m.
