General Overview
The total sky imager (TSI) 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.
