Abstract : This report describes how the climatological frequency distribution of cloud-cover is obtained and used to compute the climatological probability of cloud-free line-of-sight, or CFLOS. The probabilities can be estimated for an instantaneous point in time or for a specified time window (i.e., the probability of a continuous CFLOS for a time period of t minutes). The procedures outlined in the report are used by the USAF Environmental Technical Applications Center (USAFETAC) CPCFLOS computer program. An appendix describes the Burger Aerial Algorithm....
