Abstract
Snow-cover information is important for a wide variety of scientific studies, water supply and management applications. Various remote sensing products are used to identify spatial-temporal trends in snow cover. Snow cover maps produced by Moderate Resolution Imaging Spectroradiometer (MODIS) satellites are one of the best sources of satellite-based snow cover monitoring since they are produced on a daily basis and can be downloaded from the Internet for free. Their main limitation, however, is cloud obscuration. The accuracy of MODIS snow products must be known in order to optimize their use. Present study deals with accuracy assessment of the MODIS Fractional Snow Products as compared to snow cover image obtained from IRS-P6 LISS-III. MODIS Fractional Snow Cover Product for three snow seasons (October-May) of 2006-07, 2008-09, and 2009-10 for both MOD10A1 and MYD10A1 were downloaded from NASA Distributed Active Archive Centre (DAAC) located at the National Snow and Ice Data Centre (NSIDC) . MODIS Reprojection Tool (Version 4.1) and ERDAS IMAGINE 2011 were respectively used for converting downloaded data to the suitable format for GIS software and to subset the image for study area. IRS-P6 LISS-III images for the study area were procured from National Remote Sensing Centre (NRSC), ISRO, Hyderabad, India. The comparison of SCA% in between MODIS and LISS-III showed that performance of MODIS for snow cover mapping in Eastern Himalayan region is satisfactory.
