Whole sky cameras in stereo configurations can be used to derive cloud base height and cloud base motion.

In meteorological applications the whole sky camera is used to study cloud cover, UV index, timelapse photography of clouds, cloud fractional coverage, sky polarization, the computation of cloud base height, as well as wind speed at cloud heights.

One of the first reported whole sky cameras was based on series of pictures with lens inclined to the horizon at an altitude of 45 degrees, with the lens that covers an angular field of 90 degrees, such camera revolves about a vertical axis.
