摘要
在辐射传输模拟结果分析的基础上,提出利用云底高与下行红外辐射之间的单调关系进行云底高遥感反演的算法,并结合激光测云仪云底高实测数据对算法进行了初步验证。结果表明,该算法对中低云云底高反演的平均误差为107m,具有较高的准确性。
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.
