基于MODIS数据的雾光谱特性研究
On Fog Characteristic Based on EOS MODIS Data
-
摘要: 通过对中国东部不同区域不同季节的15幅白天MODIS影像进行雾与地物、雪、云的光谱特性差异分析,发现较利于雾与背景(地物、云、雪)分离的波段并分析其原因,为进一步利用MODIS数据进行大范围不同季节雾检测提供了一些初步建议和思路。Abstract: Based on spectral profiles sampling from fifteen EOS MODIS images of the Eastern China,spectral characteristic of water,cloud,snow,surface features and fog are analyzed.Channels suitable for fog detection are discovered and analyzed,and they are available to fog detection in different areas and seasons of China.
