DETECTION OF FOG OVER LAND USING HJ-1 DATA

Fog is a kind of meteorological disaster, which has a serious impact on social economic activities and daily life of human beings. In this paper, the fog detection model based on the characteristics of HJ-1 satellite is put forward firstly. Then the model is tested by HJ-1B data and synchronous MODIS data in southern China at January 9, 2009. By comparing the experiment results of HJ data and MODIS data, it shows that HJ data is suitable for fog detection.
