Description

The Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Earth Observing System (EOS) Terra and Aqua Missions makes daily, global observations in 36 spectral bands with spatial resolutions between 250-1000 meters. Recently research on applying MODIS observations over the entire Great Salt Lake Basin has begun with emphasis on observing snow cover and other environmental conditions with special attention to the distribution in time and space of snow cover. For snow cover there are MODIS daily, geolocated swath (level 2) products covering the basin at 500 meters. Additionally there are eight-day, 500m, level-3, gridded snow cover products that provide cloud-free observations of snow cover. Also MODIS surface reflectance, land cover, surface temperature, and albedo observations have been obtained upon which the boundaries of the entire Great Salt Lake Basin and the several sub-basins have been superimposed. Several snow cover products have been acquired for the winter/spring period of 2001 showing the capability to monitor snow cover temporal changes. Present challenges posed by slope, aspect, and land cover are being assessed relative to their impact on making accurate useful snow cover estimates. The ultimate objective is to assess MODIS products relative to their utility in obtaining improved basin runoff estimates.
