Dataset of "Seasonal evolution of a warm alpine snowpack: a multi-instrument dataset of snow microstructure at Col de Porte, French Alps"

The observation site of Col de Porte is located at an elevation of 1325 m in the northwestern part of the French Alps (45.30° N, 5.77° E) (Lejeune et al. 2019).</p><p dir="ltr">The dataset includes :<br>- <b>properties_ct.csv</b> that provides the snow properties computed from the tomography images.<br>- <b>segmented_images.tar</b> that provides the binary snow images in .zarr format.

The code zarr_example.py provides an example to read the .zarr images.</p><p dir="ltr">- <b>field_data_2021_2022.zip</b> and <b>field_data_2022_2023.zip</b> that provide the field measurements:</p><ul><li>\cutter provides density profiles from cutter measurements in .csv</li><li>\dufisss provides SSA profiles from dufisss measurements in .csv</li><li>\stratigraphy provides the traditional snow profiles in .caaml. You can open the .caaml files with the dedicated online tool niViz: <a href="niviz.org/" target="_blank">niviz.org/</a>.</li><li>\smp provides force, density, and SSA profiles from SMP measurements in .csv, as well as raw penetration-force measurements that can be opened with the <i>snowmicropyn</i> Python package.</li><li>\hissgras provides SSA profiles from hissgras measurements in .csv.</li></ul><p><br></p><p><br></p><p dir="ltr">Affiliation: Météo-France, CNRS, Univ.
