An optimized input system for long-term prediction of cloud liquid water content

In this paper, an improved method for simulating cloud liquid water content in a space-earth laser communication scenario is presented. Cloud liquid water can block high frequency laser link, so it is necessary to consider the change of cloud liquid water in satellite-ground laser communication scenarios to determine the laser link blocking situation. The original Integrated Liquid Water Content (ILWC) synthesizer adopts the input method of using statistical data of cloud liquid water in a single point, which is not exactly accurate but applicable to the scene with fixed satellite receiving point. The improved linear interpolation method for cloud liquid water statistical data input improves the overall accuracy of the input data. The simulation results are more accurate when the ground satellite receiving point is mobile, and can be used for a better resource scheduling of a multi-ground station satellite communication network.
