Detection of Fog Using HJ-1 Data

Fog is an important of environment monitoring.By radiative transfer model RT3,reflectance and brightness temperature of fog,cloud and underlying surface were simulated at different bands of CCD camera and IR camera of HJ-1 B.After analyzed simulation results,the method of monitoring fog by HJ-1B data was given.The method was tested in south China at March 12th,2009.The results show,by HJ-1B data,the fog can be monitored,but for the influence of land surfaces,the thin cloud can't be removed accurate.
