Cloud blockage in Japan area is analyzed with the long-term ground-based observation data to find candidate sites for the site diversity scheme. First, the period in which both ground-based observation data and satellite-based observation data are available is confirmed. Next, from the viewpoint of the average cloud amount, and in consideration of the installation conditions of the optical ground station, some appropriate candidate sites are selected. Finally, the cloud amount correlation values among the selected sites are obtained, and the final candidate site combinations are listed.
