Meltwater runoff and glacier mass balance in the high Arctic: 1991–2022 simulations for Svalbard

Abstract - m w. e. yr - 1 but with no statistically significant trend. The most negative annual CMB is found for Nordenskiöldland (- m w. e. yr - 1), with a significant negative trend of - m w. e. per decade for the region. Although there is no trend in the annual CMB, we do find a significant increasing trend in the runoff from glaciers of 0.14 m w. e. per decade. The average runoff was found to be 0.8 m w. e. yr - 1. We also find a significant negative trend in the refreezing of - m w. e. per decade. m w. e. yr - 1 in climatic mass balance and by 0.2 m w. e. yr - 1 in glacier runoff when averaged over all of Svalbard. There is, however, a clear difference over Nordenskiöldland, where AROME-ARCTIC simulates significantly higher mass balance and significantly lower runoff. This indicates that AROME-ARCTIC may provide similar high-quality predictions of the total mass balance of Svalbard as CARRA, but regional uncertainties should be taken into consideration. The simulations produced for this study are made publicly available at a daily and monthly resolution, and these high-resolution simulations may be re-used in a wide range of applications including studies on glacial runoff, ocean currents, and ecosystems.
