This dataset includes snow density measurements from both hemispheres. This dataset is a community effort to distribute easy to use in-situ data to improve surface mass balance modeling and remote sensing efforts. This dataset is a compilation of work from many individual researchers. When using this dataset please cite both the individual researchers who provided the data as listed in the Citation field as well as this dataset. This dataset includes snow density measurements over both ice sheets, ice caps and snow on sea ice. It excludes seasonal snow on land measurements. The dataset contains over 2,200,000 point measurements of density at different depths. The measurement methods include different sized density cutters (generally from 100 - 1000 cc (cubic centimeters)) used in snow pits, ice core sections, neutron-density methods, X-ray microfocus computer tomography, Gamma-ray attenuation, pycnometers, optical televiewer (OPTV) borehole logging, and Density-and-conductivity mixed permittivity ...
