Total Sky Imager (TSI): sky image (JPEG) - tsiskyimage

The total sky imager (TSI) measures the fraction of the sky view covered by clouds. \n \nIt provides time series of hemispheric sky images during daylight hours and retrievals of fractional sky cover for periods when the solar elevation is greater than 10 degrees. To view current sky cover retrievals at the ARM sites, see the TSI most recent sky images.

全天空成像仪（Total Sky Imager, TSI）可测量云层覆盖的天空占比。

该设备可提供日间时段的半球天空图像时间序列数据，并在太阳高度角大于10度的时段反演得到天空云量占比数据。若需查看ARM观测站点当前的天空云量反演结果，请查阅TSI的最新天空图像。
