Ice thickness measurements on South Tyrolean glaciers 1996-2014

The ice thickness of 15 South Tyrolean glaciers has been surveyed with two different types of radar systems between 1996 and 2014 within various research projects. For all glaciers apart from Weissbrunnferner, the Laser scan DEMs of the South Tyrolean glacier inventories had been taken as basis for the data processing. Earlier data has been measured with the Narod Sensor using a central frequency of 6.5 MHz, later data was recorded with a GSSI SIR 3000 system. The positions have been measured with a Garmin handheld GPS. The snow height at the time of the measurement was recorded by snow probing. The majority of the glaciers have been surveyed between 2009 and 2014, 9 glaciers in the year 2013. The methods for measurements and calculation of ice thickness are described in the various reports.
