Snow Pit Permittivity and Liquid Water Observations - Colorado and New Mexico 2020-2021

These datasets summarize field results of snow density, dielectric permittivity, and calorimeter-based liquid water content estimates. The field sites are the Jemez River Basin and Cameron Pass time series sites as part of the NASA SnowEx 2020 and 2021 time series data collection. Snow density observations were made using a 1000 cc wedge cutter and scale with 1 g precision. Dielectric permittivity observations were made with an A2 Photonics WISe sensor with a 325 cc volume of influence. The melt calorimeter observations were made to estimate liquid water content of 20-30 g snow samples taken from the WISe sensor volume; temperature precision was 0.01 degrees celsius and mass 1 g. Two datasets have been quality controlled and assessed to ensure accurate data are being reported. These data include the bulk average density and permittivity during dry snow conditions; and density, permitivitty, and liquid water content during isothermal and wet snow conditions.
