Colorado Maximum Snow Extent, 17-23 May 2000
The following image was derived from the "Maximum Snow Extent" field of the MODIS/Terra Snow Cover 8-Day L3 Global 500m Grid (MOD10A2) data set, available from NSIDC. Cloud cover (blue) is evident near Colorado Springs, because all eight days during the week had persistent cloud cover over that region.
Four input MOD10A2 tiles in HDF-EOS format were reprojected to a Universal Transverse Mercator (UTM) Zone 13 projection and converted to GeoTIFF format using the freeware HDF-EOS to GeoTIFF converter (HEG). ArcMap software was used to mosaic the four resulting GeoTIFF files, overlay county boundaries and cities, and create a map.
