Popis: The availability of a cloud free line of sight (CFLOS) for a ground-space free space optical (FSO) link is strongly dependent on a satellite’s orbit and local cloud cover spatial and temporal statistics for all potential ground stations (GS) in the satellite’s field of regard. A diverse network of multiple GS at locations with minimal and uncorrelated cloud cover can be used to maximize the availability of a CFLOS to multiple satellite orbits. Historic cloud cover data for this availability study is extracted from the ERA-Interim database which is generated, updated, and maintained by the European Center for Medium-Range Weather Forecast (ECMWF). The database contains worldwide data in 6 hour time segments from 1970 to the present. For our analysis, cloud cover data, ground station locations, and satellite ephemerides are conjointly analyzed to determine ground-space link availabilities. The results of this analysis will be presented.
