Cavitte, Marie G.P. (author), Goosse, Hugues (author), Wauthy, Sarah (author), Kausch, T. (author), Tison, Jean-Louis (author), Van Liefferinge, Brice (author), Pattyn, Frank (author), Lenaerts, Jan T.M. (author), Claeys, Philippe (author)The future contributions of the Antarctic Ice Sheet to sea level rise will depend on the evolution of its surface mass balance (SMB), which could amplify/dampen mass losses increasingly observed at the ice sheet's edge. In situ constraints of SMB over annual-to-decadal timescales consist mostly of firn/ice cores that have a surface footprint cm....journal article 2022

Sellevold, R. (author), Lenaerts, Jan T.M. (author), Vizcaino, M. (author)The Arctic is the region on Earth that is warming the fastest. At the same time, Arctic sea ice is reducing while the Greenland ice sheet (GrIS) is losing mass at an accelerated pace. Here, we study the seasonal impact of reduced Arctic sea ice on GrIS surface mass balance (SMB), using the Community Earth System Model version 2.1 (CESM2),...journal article 2021

van Kampenhout, Leonardus (author), Lenaerts, Jan T.M. (author), Lipscomb, William H. (author), Lhermitte, S.L.M. (author), Noël, Brice (author), Vizcaino, M. (author), Sacks, W. J. (author), van den Broeke, Michiel R. (author)The response of the Greenland Ice Sheet (GrIS) to a warmer climate is uncertain on long time scales. Climate models, such as those participating in the Coupled Model Intercomparison Project phase 6 (CMIP6), are used to assess this uncertainty. The Community Earth System Model version 2.1 (CESM2) is a CMIP6 model capable of running climate...journal article 2020

Muntjewerf, L. (author), Petrini, M. (author), Vizcaino, M. (author), Ernani da Silva, C. (author), Sellevold, R. (author), Scherrenberg, Meike D.W. (author), Thayer-Calder, Katherine (author), Bradley, Sarah L. (author), Lenaerts, Jan T.M. (author)The Greenland Ice Sheet (GrIS) mass balance is examined with an Earth system/ice sheet model that interactively couples the GrIS to the broader Earth system. The simulation runs from 1850 to 2100, with historical and SSP5-8.5 forcing. By the mid-21st century, the cumulative GrIS contribution to global mean sea level rise (SLR) is 23 mm....journal article 2020

Noël, Brice (author), Van Kampenhout, Leonardus (author), Jan Van De Berg, Willem (author), Lenaerts, Jan T.M. (author), Wouters, B. (author), R. Van Den Broeke, Michiel (author)We present a reconstruction of historical (1950–2014) surface mass balance (SMB) of the Greenland ice sheet (GrIS) using a high-resolution regional climate model (RACMO2; ∼ 11 km) to dynamically downscale the climate of the Community Earth System Model version 2 (CESM2; ∼ 111 km). After further statistical downscaling to 1 km spatial resolution,...journal article 2020

(author)Continuous measurements of blowing snow are scarce, both in time and space. Satellites now provide the opportunity to derive blowing snow occurrences, transport and sublimation rates over Antarctica. These products are extremely valuable and offer a continental-wide assessment of blowing snow, which is an important but unknown component of...journal article 2020

(author), Wever, Nander (author)Surface meltwater ponding has been implicated as a major driver for recent ice shelf collapse as well as the speedup of tributary glaciers in the northeast Antarctic Peninsula. Surface melt on the NAP is impacted by the strength and frequency of westerly winds, which result in sporadic foehn flow. We estimate changes in the frequency of foehn...journal article 2019

Sellevold, R. (author), Van Kampenhout, Leonardus (author), Lenaerts, Jan T.M. (author), Noël, Brice (author), Lipscomb, William H. (author), Vizcaino, M. (author)The modeling of ice sheets in Earth system models (ESMs) is an active area of research with applications to future sea level rise projections and paleoclimate studies. A major challenge for surface mass balance (SMB) modeling with ESMs arises from their coarse resolution. This paper evaluates the elevation class (EC) method as an SMB downscaling...journal article 2019

(author)We evaluate modelled Antarctic ice sheet (AIS) near-surface climate, surface mass balance (SMB) and surface energy balance (SEB) from the updated polar version of the regional atmospheric climate model, RACMO2 (1979-2016). The updated model, referred to as RACMO2.3p2, incorporates upper-air relaxation, a revised topography, tuned parameters...journal article 2018
