توزع العواصف الغبارية في سورية و آلية الكشف عنها باستخدام تقانة الاستشعار عن بعد

الملخص EN

Climatology of dust storms in Syria is compiled based on an observational data of 15 meteorological stations from1960 to 2006.

The results of the analysis showed that the number of days with dust storms is <1 days over plains and mountainous coast regions and more than 7.2 days in /Albadia/.

The storm usually occurred in Albadia.

Therefore, due to the limited ground climatic observations in the relevant regions, satellite remote sensing of objectivity, real-time and macro-scope view has become an important approach to detect dust storms in Syria.

In this paper, a dust storm process which occurred on the 22th of February, 2010 has been detected in Syria.

The Normalized Difference Dust Index (NDDI) and Brightness Temperature bands T29, T31 and T32 of MODIS/TERRA satellite data were used and tested for dust storm mapping in Syria for day and night time, by using thermal bands to detect dust at night time.

This method is effective in separating dust and other objects at the night time.

The study cocluded that remote sensing technique can play an important role in detection and analyzing dust storm.

MODIS provides a high quality data source with multi-spectral bands, appropriate spatial resolution and high temporal resolution
