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）是一款用于评估与记录云场及其动态变化的自动化成像设备。该设备为地基电子成像系统，用于监测上半球空域；其属于无源（非主动发射）系统，可通过中性、红色与蓝色三种光谱滤光片采集天顶穹顶的图像。

基于此类天空图像，我们可借助自动化云判定算法及相关处理流程，对全天域云的存在状态、分布情况、形态特征与辐射亮度进行评估。当前型号为EO System 6的全天空成像仪，可在日光、月光及星光环境下完成图像采集。
