Cloud Vertical Structure

Active cloud observations from A-Train’s CloudSat and CALIPSO satellites offer opportunities to examine the vertical structure of hydrometeor layers. We use the 2B-CLDCLASS-LIDAR merged CloudSat-CALIPSO product to examine global aspects of hydrometeor vertical stratification. We group the data into major cloud vertical structure (CVS) classes based on our interpretation of how clouds in three standard atmospheric layers overlap and provide their global frequency of occurrence.

来自A列车（A-Train）编队的CloudSat与CALIPSO卫星的主动云观测数据，为研究水凝物层的垂直结构提供了研究契机。本研究采用2B-CLDCLASS-LIDAR联合CloudSat-CALIPSO产品，对水凝物垂直分层的全球分布特征展开分析。

我们基于对三层标准大气层内云系重叠特征的解读，将数据集划分为若干主要云垂直结构（Cloud Vertical Structure，简称CVS）类别，并给出各类别的全球出现频次。
