6. One paragraph description of your model (e.g. abstract from report or
   paper);

A snow-cover model based on a heat balance method has been developed.
This model takes into account both the heat balance at the snow surface
and that of the entire snow cover and simultaneously predicts the snow
surface temperature and freezing depth. Observed or estimated incident
radiation data are required for operation of the model.
