Snow pit dataset from "Comparison of snowpack structure in gaps and under the canopy in a humid boreal forest"

This original dataset contains snow pit measurements collected at Montmorency Forest (47.29°N, 71.17°W) from 22 November, 2018 to 6 June, 2019. The study site is a balsam fir – whit birch stand on a 12° slope of north-east aspect. The dataset is described in the publication “Comparison of snowpack structure in gaps and under the canopy in a humid boreal forest” from Bouchard et al., 2022. In this dataset you can find:

inside forest gaps:

26 snow height measurements (26 data points)

26 snowpack stratigraphy (380 data points)

26 snow temperature profiles (427 data points)

26 snow density profiles (803 data points)

2 snow specific surface area (SSA) profiles (97 data points)

under the canopy:

26 snow height measurements (26 data points)

26 snowpack stratigraphy (227 data points)

26 snow temperature profiles (325 data points)

26 snow density profiles (623 data points)

2 snow SSA profiles (89 data points)

For density measurements, the height value corresponds to the center of the 3-cm thick box cutter. For the SSA, the value is measured optically at the top of the sample. This value is representative of the top 1 cm of the snow sample, as this is the typical e-folding depth of 1310 nm radiation in snow. Grain type codes for the snowpack stratigraphy corresponds to the International Classification for Seasonal Snow (Fierz et al., 2009):

PP: Precipitation particle

DF: Decomposed and Fragmented precipitation particles

RG: Rounded Grains

FC: Faceted Crystals

DH: Depth Hoar

MFpc: Melt Forms – rounded polycrystals

MFcl: Melt Forms – clustered rounded grains

MFcr: Melt Forms – melt-freeze crusts

IF: Ice Formations
