中文摘要: 选取简单云状和复杂云状作为分析对象，利用Terra/MODIS云相态产品对FY 3A/VIRR云相态产品的识别结果进行检验。对比分析采用一致性比较、差异图显示以及两种产品识别结果叠加显示等方法。结果表明：（1）简单云状条件下，FY 3A/VIRR云相态产品与Terra/MODIS 云相态识别结果具有较好的一致性，一致性接近85％；复杂云状条件下，由于Terra/MODIS 云相态识别结果中存在较多的不确定类别使两种数据识别结果的一致性下降。（2）FY 3A/VIRR和Terra/MODIS产品的不一致点主要分布在云边缘或不同云相态交界处。（3）FY 3A/VIRR和Terra/MODIS的云相态产品产生差异的原因主要来自反演算法以及产品相态分类的不同。

Abstract:FY 3A/VIRR cloud phase retrievals were evaluated by Terra/MODIS cloud phase products, with the single and complex cloud conditions discussed. In this study, consistency comparison, discrepancy image display as well as overlay display method for the two kinds of products were all employed. The analysis results show that the two kinds of cloud phase products have good consistency under the simple cloud condition, and the consistency rate is close to 85%, but under the complex cloud condition, the consistency between the two kinds of cloud phase products decreases because the Terra/MODIS cloud phase products have a lot of undefined phase cloud pixels. The different pixels of the FY 3A/VIRR and Terra/MODIS cloud phase products mainly distribute in the edges of clouds or the boundary parts of different cloud phases. The different cloud phase algorithm and cloud categorizing methods are the main cause for the different cloud phases between FY 3A/VIRR and Terra/MODIS.
