Description

snowsnow_data_struct *N/Ainitializes the following to zero:
  • pack_water (m)
  • surf_water (m)
  • vapor_flux (m)
  • pack_temp (deg C)
  • melt_energy (W/m^2)
if option.INIT_SNOW is true then the following are initialized to the values given in FILE *fsnow, else they are initialized to zero:
  • snow - 1=snow present, 0=no snow
  • last_snow - days since last snowfall
  • swq - snow water equivalent (m)
  • surf_temp - temperature of upper snowpack surface (deg C)
  • density - snow pack density (kg/m^3)
  • depth - snow pack depth (m)
