WSI: stationary calibrated red or clear quicklook images (JPEG), 10 min intervals - 10wsipartradjpg

The whole-sky imager (WSI) is an automated imager used for assessing and documenting cloud fields and cloud field dynamics. The WSI is a ground-based electronic imaging system that monitors the upper hemisphere. It is a passive, i.e., non-emissive, system that acquires images of the sky dome through three spectral filters (neutral, red, and blue). \n \nFrom these sky images, we can assess the presence, distribution, shape, and radiance of clouds over the entire sky using automated cloud decision algorithms and related processing. The current WSI model (EO System 6) is capable of image acquisition under daylight, moonlight, and starlight conditions.

全天空成像仪（whole-sky imager, WSI）是一款用于评估并记录云场及其动力学特征的自动化成像设备。该设备为地面式电子成像系统，用于监测上半球空域；其属于无源（非发射型）系统，通过中性、红光与蓝光三个光谱滤光片采集天穹图像。

依托此类天空图像，可借助自动化云判识算法及相关处理流程，对全天空范围内云的存在状态、分布格局、形态特征与辐射亮度进行评估。当前主流的WSI型号为EO System 6，可在日光、月光及星光环境下完成图像采集。
