基于MODIS云产品的AIRS像素云检测

摘要

In order to utilize the Moderate Resolution Imaging Spectroradiometer (MODIS) cloud products to detect the properties of Atmospheric Infrared Sounder (AIRS) cloud, this paper first adopted space collocation algorithm to match the MODIS and AIRS, and then combined the MODIS cloud classification mask, cloud phase mask products and the operational algorithm of MODIS cloud retrieval to realize the utilization of MODIS data to detect AIRS single field of the cloud (pixel cloud). The results show that MODIS 1 km resolution products can realize AIRS cloud classification (lower, midlevel or high clouds) and cloud phase (water, ice or mixed - phase clouds) detection.%为了利用MODIS云产品数据检测出大气红外探测器(AIRS)数据中像素云的特性,首先采用空间匹配算法对MODIS和AIRS数据进行匹配,然后结合MODIS云分类、云相态掩模及其业务上的云检测算法,实现了利用MODIS数据对AIRS像素云(单个视场云)特性的检测.结果表明,用MODIS 1 km分辨率产品数据可以实现对AIRS数据的云分类(低云、中云、高云)和云相态(水云、冰云、混合云)检测.
