MODIS_CR_Equal_Angle_Daily

The MODIS Collection 6.1 Equal-Angle Three-Hourly Cloud Regime product. This product is a discrete classification of cloud fields at the mesoscale as observed by the MODIS sensors aboard the Terra and Aqua satellites. Derived by applying the k-means clustering algorithm to joint-histograms of cloud top pressure and cloud optical thickness, the cloud regimes represent different atmospheric systems based on their cloud signatures.

本产品为中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer，MODIS）6.1版等角三分时次云型产品。该产品是对搭载于Terra和Aqua卫星的MODIS传感器所观测到的中尺度云场开展的离散分类。其通过将k-means聚类算法应用于云顶气压与云光学厚度的联合直方图生成，所得到的云型分类结果基于云系特征，可表征不同的大气系统。
