Beschreibung:
Since 1991, the first author has been running a project to study ice height change, flow velocity and deformation using GNSS ground measurements at Swiss Camp near the equilibrium line in the western margin of the Greenland Ice Sheet. The data so far came from 12 campaigns in the period 1991 to 2014, i.e. on average every two years. Recently, the HEIM-group has crossed the Greenland Ice Sheet from east to west with sleds and also determined the surface heights in 2021, it was also possible to measure the Swiss Camp area. The measurements in 2021 were made using kinematic GNSS at one-second intervals, which were evaluated using the Precise Point Positioning (PPP) method. With their results, it was now possible to extend the height change to 30 years and thus form a unique long-term time series.
