storm monitoring process mentioned above, multi-channel 
threshold methods have been used to extract the scope of dust 
storm, its intensity, and then monitoring its moving trace. Result 
shows greet agreement with the meteorological department 
monitoring. Conclusions can be gotten: CD Multi-temporal data 
has high timeliness, so it can be used to monitor the moving 
trace of dust storm; ©The intensity grades of dust storm should 
be estimated by the temperature difference between the 
twentieth band and the thirty-first band.
