Layer Abstract

Hall, D.K., G.A. Riggs, and V.V. Salomonson. 2006, updated daily. MODIS/Terra snow cover daily L3 global 0.05deg CMG V005. Boulder, Colorado USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/mod10c1.html. Background: This data set consists of 7200 columns by 3600 rows of global arrays of snow cover in a 0.05 degree Climate Modeling Grid (CMG). The Confidence Index (CI) was developed to provide users with an estimate of confidence in the snow value reported for a cell. This index indicates how confident the algorithm is that the snow percentage in a cell is a good estimate based on data such as snow, snow-free land, cloud, and other, binned into the grid cell. A high CI (max = 100%) is indicative of cloudless conditions and good data values, and that the snow percentage reported is a very good estimate. A low CI (min = 0%) is indicative of a lot of cloud cover and that the snow percentage may not be a good estimate because of the cloud cover obscuring all or parts of a cell.

Server Abstract

This map server from the National Snow and Ice Data Center (NSIDC) provides cryospheric data and information pertinent to the Northern Hemisphere. Map images and source data are provided through Open Geospatial Consortium, Inc. (OGC) protocols (WMS, WFS, and WCS). For other related OGC data sets from NSIDC, see also the Atlas of the Cryosphere at: http://nsidc.org/data/atlas/.
