2012年FY2D VIRR云分类(CLC)产品

根据云的特性和形成过程将云区分归类的体系，通常考虑的几个因子是：云的外观、高度、形成过程和云粒子组成。我国按云底高度将云分为低、中、高3族，然后再区分为10属(卷云、卷层云、卷积云、高层云、高积云、层云、层积云、雨层云、积云和积雨云)，并进一步细分为29类(如淡积云、碎积云、透光层积云、堡状高积云、毛卷云等)。

A classification system for distinguishing and categorizing clouds based on their characteristics and formation processes. Several key factors are typically taken into consideration: cloud appearance, altitude, formation process, and cloud particle composition. In China, clouds are divided into three families based on cloud base altitude: low-, middle-, and high-level clouds, then further categorized into 10 genera, including cirrus, cirrostratus, cirrocumulus, altostratus, altocumulus, stratus, stratocumulus, nimbostratus, cumulus, and cumulonimbus, and further subdivided into 29 species such as cumulus humilis, cumulus fractus, stratocumulus translucidus, altocumulus castellatus, cirrus fibratus, etc.
