Remote Sensing of Dust Storms Over the Indo-Gangetic Basin

Dust storms are naturally occurring events that take place in arid and semi- arid regions of the Earth, temperate, tropical and sub-tropical latitudes characterized by dry soil/sand. Arid regions around the Arabian Sea like Iran, Afghanistan, India and Pakistan usually experience a high frequency of dust storms, approximately 30 events per year. Dust storms are believed to be one of the most serious environmental hazards. In this paper, we show the usefulness of optical remote sensing data for monitoring dust storms. The Moderate Resolution Imaging Spectroradiometer (MODIS) and the Multiangle Imaging Spectro Radiometer (MISR) on board Terra/Aqua platforms can be used for the optical sensing of dust storms. The different viewing angles of MISR provide information about dust particles through their discrimination from other suspended particles. In this paper, we examine a dust event over the Indo-Gangetic basin, which occurred on June 9-10, 2003.
