Abstract
A new type of air-ground communication application framework named FACT (framework for air-ground communication technology with weather-modification aircraft) is presented to track and command weather-modification aircraft to perform ideal cloud seeding. FACT provides a set of solutions from three perspectives, namely, onboard, onground and air-to-ground, with the core purpose of solving the problems of the rapid exchange of information, contract analysis and identifying potential seeding areas when flight plans and meteorological conditions change. On board, the observed data are processed centrally and transmitted downward through air-to-ground communication. The real-time application and sharing of aircraft detection data are strengthened on the ground, and potential areas of operation are automatically identified based on ground data. The communication between the air and the ground achieves a technical breakthrough by realizing double satellite links, adaptive data transmission and VPN channel encryption. Additionally, an application based on FACT is designed and implemented for the real-time command of weather-modified aircraft. This approach has become the key air-to-ground communication system support for more than 40 Chinese aircraft and the big data service support center of airborne data to ensure improved operation of weather-modification aircraft in China.

Summary
Weather modification is to reduce or avoid meteorological disasters by consciously influence on the local atmospheric physical and chemical processes through scientific and technological means. How to make good use of aircraft observations during aircraft flight is one of the key issues to improve the quality of seeding operations In response to this problem, a new framework with high air-to-ground communication information support and decision-making capabilities is proposed, which realizes the realtime transmission of airborne observations from aircraft to the weather modification ground command center, and a new method to ensure uninterrupted transmission and automatically identify the seeding potential area. In this framework, relying on air-ground-based observations, automated data reanalysis is performed to help experts determine the potential seeding area around the aircraft flight path, thereby temporarily adjusting some of the routes and achieving the goal of improving seeding effectiveness
