Optical communication is an important technology for future space networks. However, compared with inter-satellite optical communication, satellite-ground optical communication is more challenging because of weather, which are mostly cloud factors. To deal with this problem, an effective strategy is to achieve ground station site diversity. In this paper, we propose a method to determine the range of clouds that affects satellite-ground optical links for a certain ground station. Given the number of candidate ground stations, through processing the cloud products of the Himawari-8 GEO satellite, we obtained the cloud coverage data corresponding to each ground station. Then, by calculating the availability probability of possible combinations of ground stations, the network with the highest availability is chosen as the optimal optical ground station network. By calculating the availability probability with real cloud data, the results of ground station site selection in mainland China are obtained.
