Ice thickness and bed topography for Rabots glaciär, northern Sweden
Zhuo Wang, Neil Ross, Thomas Frank, Jamie Barnett, Ilaria Santin, Martin Houssais, Johanna Dahlkvist, Nina Kirchner
The dataset is based on a radio-echo sounding (RES) survey conducted in April 2025 on Rabots glaciär, northern Sweden, along with subsequent data analysis. It contains:
I. Point values of RES-measured ice thickness.
II. Glacier-wide gridded ice-thickness and corresponding uncertainty, derived by combining RES-measured ice thickness and ice-thickness modelling.
III. Glacier-wide gridded bed topography and filtered bed topography, obtained by subtracting gridded ice-thickness from gridded surface elevation.
Rabots glaciär is one of Sweden’s four so-called reference glaciers (glaciers for which more than 30 years of continuous measurements are available) included in the World Glacier Monitoring Service (WGMS) database.

Data description
This dataset consists of one csv file and four tif files (GeoTIFF).

The surface elevation used is taken from the Arctic DEM strip (Porter 2022) acquired in October 2024 and corrected using a vertical offset of 2.5 m based on dGNSS point elevations measured in April 2025.
RGIT.tif Gridded ice-thickness
Glacier-wide gridded ice-thickness (m) for Rabots glaciär with a spatial resolution of 10 m x 10 m. The coordinate reference system (CRS) used is SWEREF99 TM (EPSG:3006).
RGIT_Uncertainty.tif Ice-thickness uncertainty
Corresponding glacier-wide ice-thickness uncertainty for Rabots glaciär with a spatial resolution of 10 m x 10 m. The coordinate reference system (CRS) used is SWEREF99 TM (EPSG:3006).
RGBED.tif Gridded bed elevation
Glacier-wide gridded bed elevation for Rabots glaciär with a spatial resolution of 10 m x 10 m. The map is provided in the SWEREF99 TM coordinate reference system (EPSG:3006) and is calibrated to the geoid using the SWEN17_RH2000 model.
RGBED_Filtered.tif Smoothed bed elevation
Corresponding smoothed bed elevation for Rabots glaciär, obtained using a Gaussian filter with a spatial smoothing scale of approximately 60 m. The map has a spatial resolution of 10 m × 10 m, is provided in the SWEREF99 TM coordinate reference system (EPSG:3006), and is calibrated to the geoid using the SWEN17_RH2000 model.
