Dust particles have dangerous impacts on human health, the environment, and the economy . Dust storms don't just happen in the middle of the desert. They happen in any dry area where loose dirt can easily be picked up. Grains of sand tossed into the air by the wind usually fall back down to the ground after a few hours. So am planned to extract dust storm from MODIS data , if anybody have great experience in related field please help me out in the same .
