One-line model description SNOWPACK is a multi-purpose snow and land-surface model, which focuses on a detailed description of the mass and energy exchange between the snow, the atmosphere and optionally with the vegetation cover and the soil. It also includes a detailed treatment of mass and energy fluxes within these media.
Extended model description SNOWPACK has originally been developed to support avalanche warning (Lehning et al., 1999) and thus features a very detailed description of snow properties including weak layer characterization (Stoessel et al., 2009), phase changes and water transport in snow (Hirashima et al., 2010). A particular feature is the treatment of soil and snow as a continuum with a choice of a few up to several hundred layers. While a main application is still on avalanche warning in countries from Switzerland (Schirmer et al., 2009) to Japan (Nishimura et al., 2005), the applications range from climate change assessments (Rasmus et al., 2004; Bavay et al., 2009) and superimposed ice simulations (Obleitner and Lehning, 2004) to permafrost sensitivity studies (Luetschg et al., 2008) and the simulation of snow storage (Olefs and Lehning, 2010).

Describe input parameters It requires the following meteorological parameters:
  • air temperature (TA)
  • relative humidity (RH)
  • wind speed (VW)
  • incoming short wave radiation (ISWR) and/or reflected short wave radiation (RSWR)
  • incoming long wave radiation (ILWR) and/or surface temperature (TSS)
  • precipitation (PSUM) and/or snow height (HS)
  • ground temperature (TSG, if available. Otherwise, you will have to use MeteoIO's data generators to generate a value) or geothermal heat flux
  • snow temperatures at various depths (TS1, TS2, etc if available and only for comparisons, see section Snow and/or soil temperatures)

Describe output parameters Snowpack creates various output files:
  • the current state of its soil and snow layers in ".sno" files;
  • the current state of its hazard relevant data in ".haz" files;
  • a time serie of snow profiles;
  • a time serie of the meteorological data and fluxes as used in the model.
