Monitoring glacier mass change in northern Sweden from 2003 to 2023 using satellite altimetry data
The analysis of glacier mass changes in northern Sweden from 2003 to 2023 employed the non-repeat observation method, utilizing data from altimetry data ICESat and ICESat-2, along with Swedish national DEM and RGI v7.0 glacier boundary. The total volume decreased by -2.78 ± 0.58 km³, corresponding t...

The analysis of glacier mass changes in northern Sweden from 2003 to 2023 employed the non-repeat observation method, utilizing data from altimetry data ICESat and ICESat-2, along with Swedish national DEM and RGI v7.0 glacier boundary. The total volume decreased by -2.78 ± 0.58 km³, corresponding to a total mass loss of 10.41 ± 6.60 m w.e. over the past two decades. These changes contribute approximately 6.52∙10−3 mm to global sea-level rise. The study reveals a general trend of glaciers losing mass throughout the observation period. Additionally, in-situ measurements in northern Sweden were obtained to evaluate the results from the altimetry remote sensing method.
