Field Investigations

The first campaign in April 2009 ended successfully with the installation of two Automatic Weather Stations (AWS) on the Zhadang Glacier (∼ 5500 m a.s.l.), complementing an AWS operated by the ITP. In such harsh conditions, the approx. 80 kg of measuring equipment were carried on horses and yacks that were hired from Tibetan nomads living in the valley. This makes of the Zhadang glacier one of the most elaborately equipped "laboratory glacier" in Central Asia.

Both AWS are inspected every six months and will record meteorological data during at least two years. The data is used to produce and calibrate detailed models for snow and ice melt.

One year of measurements at the AWS1: air and ice temperatures from May 2009 to May 2010


In addition to the AWS, two cameras were installed by the TU Dresden on the glacier side. Since May 2010, they take one picture a day to record glacier area and volumes changes using stereographical techniques.
