This set of snow parameters over the Colorado River Basin was supplied by the investigator magnetic tapes. Snow parameters called the polarization ratio (PR) and gradient ratio (GR) are computed for both daytime and nighttime from brightness temperatures measured at 18 and 37 GHz. The GR values are indicators of the spatial distribution of snow water equivalent in the area snowpack, and may be used to predict the timing of the onset of snow melting. Both PR and GR are gridded onto a map that covers from 32 to 46 deg N. latitude and 105 to 120 deg W. longitude, with a spatial resolution of 0.2 deg x 0.2 deg. Each map contains 3 data days (or 6 calendar days) of data. There are altogether seven years of data, which span December through May of each year starting with 1978.
