Snow profile
The presence of summer hoar horizons and changes in density suggests that the 4m pit represents 13 years of accumulation.

The weather station has recorded data from the 15th Nov 2004 through to collection on the 3/12/2007. A problem with storage limits prevented continual data throughout 2005, but this was addressed by K049 during 2005/06 season. The record from Nov 2004 to Dec 2007 for air temperature, snow depth (i.e. accumulation changes), solar radiation, pressure and snow temperature is shown below (Fig. 4).
