tsi: Total Sky Imager

The total sky imager (TSI) measures the fraction of the sky view covered by clouds.

It 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.
