These are some example snowpack profiles for the Atwater site in Alta, Utah computed using the SLF's SNOWPACK simulation tool.
Figure 2: Yesterday's snowpack profiles for a flat slope, north-facing 35 degree slope (NF), east-facing 35 degree slope (EF), south-facing 35 degree slope (SF) and west-facing 35 degree slope (WF).
Simulations are driven using data from the Alta Atwater Snowstudy Plot. Symbols: rFC - rounding facets, IF - ice formation, MF - Melt freeze, SH - surface hoar, DH - depth hoar, FC - faceted crystals, RG - rounded grains, DF - decomposing and fragmenting particles, PP - precipitation particles. Note that the time is in UTC. Local Utah time is UTC -7 hours.
