A Dust-storm Process Dynamic Monitoring with Multi-temporal Modis Data
نویسنده
چکیده
In recent years, the frequency of dust storm is rising. Dust storm can impact the climate changes and cause great damages to people. It is very necessary to monitor the disasters accurately. In this paper, a dust storm process occurred in April, 2006 has been monitored. According to the reflect and absorb characteristic of dust storm, the scope of dust storm is extracted successfully;and the intensity grades are estimated, then the moving trace is monitored by multi-temporal data. Result shows greet agreement with the meteorological department monitoring. Conclusion can be gotten: the dust storm process dynamic monitoring with multi-temporal data has great application prospect.
