Description

PROMICE-2022 Ice Mask

The PROMICE-2022 Ice Mask is a high-resolution outline of the contiguous ice masses of the Greenland Ice Sheet. The dataset is derived from a true-colour, multi-band mosaic of Sentinel-2 satellite images at 10 m resolution, compiled using the SentinelHub Cloud Processing API. The mosaic was generated using the most recent valid pixels from August 2022, ensuring high temporal and geometric accuracy.

Manual editing and mapping was conducted at a scale of around 1:25,000, after which quality assessment was performed independently of the mapping operator, before finally being merged into one coherent dataset. The manual mapping process is further supported by data from the Danish Agency for Climate Data (KDS), including mosaics of Sentinel-2 and SPOT 6/7 imagery, as well as recent vector data from topographical mapping.

Issues with the dataset

We welcome feedback from the scientific glaciology community regarding the PROMICE-2022 Ice Mask dataset. Issues, suggestions, or corrections can be submitted via the project’s GitHub repository.

Terms of use

If the data are presented or used to support results of any kind, please include an acknowledgement and references to the applicable publications:

  • Include a reference to the peer-reviewed article presenting the PROMICE-2022 Ice Mask:
    Luetzenburg G. et al. (preprint) PROMICE-2022 Ice Mask: A High-Resolution Outline of the Greenland Ice Sheet from August 2022. Earth Syst. Sci. Data. https://doi.org/10.5194/essd-2025-415
  • Include a reference to the data itself (see citation and DOI at the top of this page).

If the data are crucial to the main conclusions of a manuscript or presentation of any kind, please contact a relevant member of the PROMICE team at GEUS and include them in the manuscript author list.

Detailed description

The PROMICE-2022 Ice Mask is provided as line and polygon vector layers in the GeoPackage format (.gpkg), with coordinates referenced in the WGS NSIDC Sea Ice Polar Stereographic North projection (EPSG:3413). The 10 m datasets are provided as sparse rasters, meaning only the pixels along the ice margin and nunatak outlines are stored. This reduces file size by several orders of magnitude while preserving the high-resolution geometry needed to mask or classify remote-sensing imagery. Users may fill the raster inward if needed.

The ice sheet boundary is classified into land-terminating and marine-terminating sectors. The dataset includes all contiguous ice that forms part of the Greenland Ice Sheet, as well as local glaciers and ice caps that are physically connected to it. Debris-covered ice, including lateral and medial moraines, stagnant or dead ice, snowfields, and supraglacial lakes are included. Ice-marginal lakes and unconnected peripheral glaciers or ice caps are excluded.
