Density of freshly fallen snow in the central Rocky Mountains
MetadataShow full item record
New snow density distributions are presented for six measurement sites in the mountains of Colorado and Wyoming. Densities were computed from daily measurements of new snow depth and water-equivalent from snow board cores. All data were measured in wind-protected forest sites. Observed densities of freshly fallen snow ranged from 10 kg m-3 to 257 kg m-3. Average densities at each site based on four years of daily observations ranged from 72 to 103 kg m-3. Seventy-two percent of all daily densities fell between 50 and 100 kg m-3. Approximately 5% of all daily snows had densities below 40 kg m-3. ...
