DTU gravity compilation

The dataset represents a regional compilation of terrestrial, marine, airborne and satellite-derived gravity data for Greenland, prepared by DTU Space. The compilation includes calculation of free-air (Faye) and terrain-corrected Bouguer anomalies based on homogenised gravity observations. In areas lacking direct measurements, satellite-derived gravity models have been applied as supplementary data. Over the Greenland Ice Sheet, Bouguer anomalies are calculated using an ice thickness model based on Bamber et al. (2013). The dataset provides a regional gravity framework for geological and geophysical interpretation.

Purpose
The purpose of the dataset is to provide a consistent, regionally complete gravity framework for Greenland to support geological mapping, tectonic analysis and resource assessment. The compilation integrates multiple data sources into a unified model.

Supplemental Information
The dataset represents a regional compilation rather than original individual observations. Data coverage and resolution vary depending on the underlying data sources. Use for detailed local analysis should consider variations in data density and origin.

Statement
The dataset has been established as a compilation of terrestrial, marine, airborne and satellite-derived gravity observations maintained by DTU Space. Data have been homogenised and adjusted to a common reference framework prior to calculation of free-air and Bouguer anomalies. Terrain corrections are based on digital elevation models. Over the Greenland Ice Sheet, ice thickness information is derived from the model presented by Bamber et al. (2013), which integrates radar and satellite data to determine ice thickness and bed topography. In areas without direct gravity observations, satellite-derived gravity models are used as supplementary input.
