摘要
为了利用MODIS数据与数值模式估测云的垂直结构,通过运行PSU/NCAR MM5非静力数值模式,以模式输出的温湿廓线与MOD06云顶气压产品插值得到云顶高度,并利用WR95探空分析算法判定云底高度;以CloudSat/CPR主动遥感数据为真值进行云垂直结构的对比试验。初步结果表明:结合MODIS云产品与中尺度数值模式输出的诊断分析产品估测云的垂直结构是可行的,这为不依赖云雷达主动遥感体系获得云的垂直结构提供了一种新的方法。
To evaluate the cloud vertical structure with MODIS data and the numerical model,the cloud top height was interpolated from MOD06 cloud top pressure product and the temperature humidity profiles by running the PSU/NCAR MM5 model.The location of the cloud-layer base was determined by WR95 algorithm.Lastly,CloudSat/CPR products taken as the true cloud vertical structure were compared with the results derived from the two methods.The preliminary results show that MODIS cloud products combined with the mesoscale model output data is feasible to estimate the cloud vertical structure,which is a new way not relaying on CloudSat/CPR initiative remote sensing system to estimate cloud vertical structure.
