云检测

云检测产品（Cloud Mask），将像元指定为完全有云或完全无云，并附加可信度信息。云检测/晴空检测算法主要提供像素级晴空或云的检测结果，云检测算法利用云和晴空在光谱、空间及时间方面的不同特性来进行区分，可提供 4 类像素级云检测结果，包含晴空，可能晴空、可能云、及云。卫星的云检测产品，时间频率10分钟，空间分辨率2km。

Cloud Mask product classifies each pixel as either fully cloudy or fully cloud-free, and attaches confidence information. Cloud detection/clear-sky detection algorithms primarily provide pixel-level detection results for clear skies or cloud cover. These algorithms distinguish between clouds and clear skies by leveraging their distinct spectral, spatial, and temporal characteristics, and can output four categories of pixel-level cloud detection results: clear sky, probable clear sky, probable cloud, and fully cloudy. This satellite-based cloud detection product has a temporal frequency of 10 minutes and a spatial resolution of 2 km.
