Abstract: This data set provides Moderate Resolution Imaging Spectroradiometer (MODIS) data from the Cold Land Processes Field Experiment (CLPX). These data are delivered in geographic (GEO) and Universal Tranverse Mercator (UTM) grids covering the Large-Regional Study Area (LRSA) in Colorado, USA. The data cover the time period Feb 15 (day 046) through May 15 (day 135), a total of 90 days, for both study ... years (2002-2003). Data were resampled from the original HDF-EOS product files containing either swath data or gridded data. Parameters include calibrated radiances, surface refelctance, snow cover, surface temperature/emissivity, and vegetation indices. Gridded data are provided in two formats: raw binary (including an ASCII header) and GeoTiff. Both formats are provided as output from the MODIS Reprojection Tool which is used to regrid MODIS gridded data.
