摘　　要：本研究旨在基于风云三号极轨卫星B星和C星的VIRR数据针对齐齐哈尔市2017年5月3日-5日的一次明显沙尘天气过程进行不同时次沙尘范围及面积的提取,采用多波段组合显示和可见光、短波红外、远红外波段阈值调整的方法进行了沙尘信息判识提取,结果表明5月3日起沙尘随着由西流动的云层向东推动,4日在市区沙尘信息范围最大,5日随着云层的增多由多云天气转向降雨天气,沙尘天气过程结束。风云三号极轨卫星数据空间分辨率和时间分辨率可以很好的进行沙尘天气过程的动态监测。Based on the VIRR data of Fengyun-3 polar orbiting satellite B and C, this study aims to extract the dust range and area at different times during an evident dust weather process in Qiqihar from May 3 to 5, 2017. The results show that the sand and dust information range is the largest in the urban area on the 4th and the end of the sand and dust weather process is from cloudy weather to rainy weather on the 5th with the in- crease of clouds. The spatial and temporal resolution of Fengyun-3 polar orbiting satellite data can be used for dynamic monitoring of dust weather process.
