复旦大学云辐射综合分析系统

复旦大学云辐射综合分析系统（Fudan University Cloud-Radiation Integrated Analysis System, FDU-CRIAS）是由复旦大学大气与海洋科学系自主研发的云辐射特性综合分析平台。该系统集成了团队“大禹”辐射传输模式、静止卫星遥感反演算法和“大禹”云图大模型预报技术，专注于云辐射的实时监测、精准反演及短临预报，为天气气候研究和业务应用提供高精度数据支持。

FDU-CRIAS提供了中国新一代静止气象卫星风云四号AGRI成像仪多通道亮温、全天时云物理特性、辐射等实时和预报产品。该系统依托复旦大学在大气遥感领域的学科优势，已应用于东亚区域云辐射相互作用研究及极端天气诊断。其中，静止卫星全天时云物理特性反演算法已在中国气象局人工影响天气中心完成业务化部署，并在人影中心“天工”指挥平台成功上线，在2024年西南林火和上海进博会期间、2025年“春雨” 行动和宁夏六盘山增雨试验中为无人机、飞机作业方案设计和跟踪指挥提供了重要的数据支撑。未来，团队将持续优化算法并拓展卫星数据应用范围。
