SOS: Snow Pit Data


Snow Pit data acquired from manual snow pits following protocols and symbology from the International Classification for Snow on the Ground (see document attached titled IntClassificationSnowOnGround.pdf) collected during the Sublimation of Snow (SOS) field project. Snow pits were dug approximately every 24 to 48 hours from 6 January to 16 March 2023. The main measurements taken from each snow pit included total snow depth, surface temperature, snow temperature (every 10 cm), snow density (10 cm average), snow crystal size, snow crystal type, and layer hardness. See the readme file for more detail.
