Automatic Weather Station at Evans Piedmont Glacier

An automatic weather station has been established near the 2004/2005 ice coring site that records several parameters to help characterise the meteorology and snow accumulation regime of the area (Fig.2).

Parameters measured as of 15 November 2004 are:
  • Air Temperature at 2.5 height
  • Snow accumulation, and air temperature at 1.5 m height
  • Dew point temperature at 2.5 m height
  • Solar radiation (incoming) at 2.5 m height
  • Snow temperatures (thermistor resistance) from 0.135 to 2.085 m depth in at 13.5 cm intervals

To these were added as of 01 December 2005

  • Barometric pressure
  • Wind speed (ultrasonic)
  • Wind direction (ultrasonic)
