Processed GNSS data of four stations at 79°N Glacier (Nioghalvfjerdsbraeen Glacier) in northeast Greenland from 2017 (see link in "Further details").The GNSS data were processed using the GIPSY-OASIS software Package with high-precision kinematic data processing methods (Nettles et al., 2008) with ambiguity resolution using Jet Propulsion Laboratory (JPL)'s orbit and clock products, constraint on kinematic position solution. We use the GIPSY-OASIS version 6.4 developed at JPL, and released in January 2020 (Bertiger et al., 2020). We use JPL final orbit products which include satellite orbits, satellite clock parameters and Earth orientation parameters. The orbit products take the satellite antenna phase center offsets into account. The atmospheric delay parameters are modelled using the Vienna Mapping Function 1 (VMF1) with VMF1grid nominals (Boehm et al., 2006). Corrections are applied to remove the solid Earth tide and ocean tidal loading. The amplitudes and phases of the main ocean tidal loading terms are ... : Data were measured in the field by Daniel Steinhage, Niklas Neckel, Ole Zeising and Shfaqat Abbas Khan. Data processing was done by Veit Helm, Shfaqat Abbas Khan and Ole Zeising. This dataset has been planned by Angelika Humbert as part of the iGRIFF expeditions and as contribution to GROCE.If you have questions, please contact Ole Zeising ([e-mail]) or co-authors. ...
