Abstract:

This is the third part of a planned Northern Hemisphere atlas of probabilities of cloud-free lines-of-sight between the earth and space. The probabilities are for the mid-season months January, April, July, and October four times of day 0000-0200 LST, 0600-0800 LST, 1200-1400 LST, and 1800-2000 LST and three elevation angles 10, 30, and 90 degrees.
