[ Update this Record ]

Summary

Abstract: This data set contains firn physical properties measured in two meter snow pits and from deeper, 12- to 30-meter firn cores. The physical properties measured in the snow pits include density, permeability and microstructure (grain size and pore size). The physical properties measured on firn cores include density, permeability, diffusivity and microstructure. Data are available in Microsoft Excel format and ADOBE PDF and are available via FTP.
