Sharma, AR, Kharol, SK, Badarinath, KVS (2009). Satellite observations of unusual dust event over North-East India and its relation with meteorological conditions. JOURNAL OF ATMOSPHERIC AND SOLAR-TERRESTRIAL PHYSICS, 71(17-18), 2032-2039.

An unusual intense dust storm occurred over North-East region of India on 17 March 2009, which was analyzed using multi-satellite data sets. Terra MODIS AOD(550) showed high values on 17 March 2009 with low values of Angstrom exponent (g.), suggesting coarse mode particle loading in the atmosphere. NCEP temperature and relative humidity anomalies showed high temperature and low humidity during March 2009. Dry weather conditions due to deficit rainfall during January-March 2009 and higher winds resulted in unusual dust storm over the region. Satellite observations of aerosol optical depth variations suggested increased aerosol loading in March 2009 due to dust storm. (C) 2009 Elsevier Ltd. All rights reserved.
