Abstract

Elements of the snow cover algorithm to be implemented with the Earth Observing System (EOS) MODerate resolution Imaging Spectroradiometer (MODIS), scheduled for launch in 1998, are being developed and tested. The MODIS snow cover algorithm utilizes unique spectral and spatial characteristics of the MODIS to identify snow by reflectance characteristics. The algorithm implements a series of criteria tests and a Normalized Snow Difference Index (NSDI) to identify snow and to discriminate snow from many types of clouds. Landsat Thematic Mapper (TM ) data, simulated MODIS data, and Advanced Very High Resolution Radiometer (AVHRR) data are used to prototype the algorithm. The snow cover algorithm has been tested on a variety of Landsat TM scenes with consistent snow identification results.
