摘要
以 2 0 0 1年 3月到 5月的几次沙尘天气为例 ,介绍基于地表覆盖的AVHRR反照率的反演结果 ,并与TSP(沙尘干量 )和Si(硅 )进行对比分析 ,发现它们具有较好的相关性 ,从而揭示了沙尘暴发生前后地表能量的变化状况 。
Chinese and Japanese established a joint project in 2001 to set up ground observation stations along dust source areas, transportation roads, precipitation areas collecting TSP (dry dust precipitation) and utilize AVHRR data to retrieve albedo (surface energy), and then we selected data from retrieved albedo temporal imagery to make curves. The result showed that there were good correlation between these two kinds of curves. It was proved that the albedo could be one of the physical parameters for predicting dust storm in future monitoring systems.
