Atlas of Cloud-Free Line-of-Sight Probabilities. Part 5. North Africa and the Middle East

摘要

This is the fifth 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 deg. Parts 1, 2, 3, and 4 depicted cloud-free line-of-sight probabilities for Germany, the USSR, the USA, and Europe, respectively.
