Feenstra, Thirza (author)The Greenland Ice Sheet (GrIS), which stores freshwater equal to more than seven meters of potential sea level rise, strongly interacts with the global, Arctic and North Atlantic climate. In a warming climate, the GrIS has been losing mass and is projected to lose mass at an increasing rate. The interactions between the GrIS and the climate have...master thesis 2024

Trotereau, Jeremy (author)The Greenland Ice Sheet (GrIS) is an ice sheet situated on the island of Greenland. It has a surface area of about 1.74 million km² and contains a volume of ice equivalent to 7.4 m of global mean sea level rise. The GrIS is vulnerable to climate disruptions such as anthropogenic climate change. As a result of increased greenhouse gas emissions,...master thesis 2023

Kempenaar, Gydo (author)Uncertainty in ice sheet modelling affects centennial and longer time-scale projections of the Greenland Ice Sheet's (GrIS) sea level contribution. One source of this uncertainty is the interaction between the ice sheet’s evolution and the Earth’s deformation in response to changes in the applied surface loading as the ice sheet waxes and wanes....master thesis 2022

Rudlang, Julia (author)The Greenland ice sheet (GrIS) is an important component of the climate system and is a key contributor to future sea level rise, as it is storing frozen water that would raise sea levels by 7.4 m should it all melt (Bamber et al., 2018). Of particular concern is the amount of global warming we are facing now and in the future, as it is becoming...master thesis 2022

Muntjewerf, L. (author)Human-induced climate change is one of the challenges of our time. The increasing global mean temperature, shifts in precipitation patterns, and the rising sea level threaten ecosystems and natural resources, and pose a great risk on society at large. Policymakers need information about the expected impacts, as accurate as possible, in order to...doctoral thesis 2021

Sellevold, R. (author)One of the major consequences of ongoing global warming is the melting of the Greenland ice sheet (GrIS). The GrIS, as the world’s second largest freshwater reservoir, has the potential to raise sea levels by 7.4 m (Bamber et al., 2018a,b). Such a sea level rise would have a devastating effect on coastal societies, where a large fraction of...doctoral thesis 2021

Sellevold, R. (author), Vizcaino, M. (author)Future Greenland ice sheet (GrIS) melt projections are limited by the lack of explicit melt calculations within most global climate models and the high computational cost of dynamical downscaling with regional climate models (RCMs). Here, we train artificial neural networks (ANNs) to obtain relationships between quantities consistently...journal article 2021

Izeboud, M. (author), Lhermitte, S.L.M. (author), Van Tricht, K. (author), Lenaerts, J. T.M. (author), Van Lipzig, N. P.M. (author), Wever, N. (author)To better understand and quantify the impact of clouds on the Greenland Ice Sheet surface mass balance (SMB), we study the spatiotemporal variability of the cloud radiative effect (CRE). The total CRE is separated in short-term and long-term impacts by performing multiple simulations with the SNOWPACK model for 2001-+2010. The annual total...journal article 2020

(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

(author)The Greenland ice sheet (GrIS) is now losing mass at a rate of 0.7 mm of sea level rise (SLR) per year. Here we explore future GrIS evolution and interactions with global and regional climate under high greenhouse gas forcing with the Community Earth System Model version 2.1 (CESM2.1), which includes an interactive ice sheet component (the...journal article 2020

Bemelmans, Mark (author)By combining the RACMO2.3 RCM output with GRACE non-tidal ocean and atmospheric pressure anomaly as well as geo-center motion corrections from 2003 to 2017, a physics-based model to estimate the vertical displacement of the Greenland surface bedrock is created. This model is able to convert the mass and pressure anomalies into vertical...student report 2019

Xu, Z. (author)In the 21st century, polar land ice melting became one of the driving factors of global sea level rise, which is discussed widely by the media and the public. Although the fact of the shrinking ice caps and accompanying changes in the sea level is established, the actual amount of polar ice melting still needs to be quantified in separate...doctoral thesis 2019

Izeboud, Maaike (author)As of yet, there is no consensus on the role of the cloud radiative effect (CRE) on the Greenland Ice Sheet (GrIS). This study focuses on the seasonal and temporal variability of the CRE, to better understand the response of the firn. To do so, we combine satellite observations, climate-model output, and a snow model. We separate short-term and...student report 2019

Ditmar, P.G. (author), Tangdamrongsub, N. (author), Ran, J. (author), Klees, R. (author)We propose a technique to regularize a GRACE-based mass-anomaly time-series in order to (i) quantify the Standard Deviation (SD) of random noise in the data, and (ii) reduce the level of that noise. The proposed regularization functional minimizes the Month-to-month Year-to-year Double Differences (MYDD) of mass anomalies. As such, it does...journal article 2018

Prakash, Abhay (author)The Greenland Ice Sheet has a total volume of 2900000 km3. In recent decades, the ice-sheet has been losing mass rapidly and has nearly doubled its contribution to sea-level rise. One main contributing factor has been the recent widespread acceleration of the tidewater glaciers that terminate in deep and narrow glacial fjords. However, our...master thesis 2017

Ran, J. (author)The Greenland ice sheet (GrIS) is currently losing mass, as a result of complex mechanisms of ice-climate interaction that need to be understood for reliable projections of future sea level rise. The thesis focuses on the estimation of mass anomalies in Greenland using data from the GRACE satellite gravity mission. Monthly GRACE gravity field...doctoral thesis 2017

Michailidou, E. (author)Today’s climate warming is unequivocal. Evidence from observations and satellite records show that Arctic Ocean is losing its summer sea ice cover with a rapid pace and is dominated by young and thinner ice. The ice loss has already caused heating of the overlying atmosphere. At the same time, the Greenland ice sheet (GIS) surface mass balance...student report 2017

Ran, J. (author), Ditmar, P.G. (author), Klees, R. (author), Farahani, H. (author)We present an improved mascon approach to transform monthly spherical harmonic solutions based on GRACE satellite data into mass anomaly estimates in Greenland. The GRACE-based spherical harmonic coefficients are used to synthesize gravity anomalies at satellite altitude, which are then inverted into mass anomalies per mascon. The limited...journal article 2017

Fyke, J.G. (author), Vizcaino, M. (author), Lipscomb, W. (author), Price, S. (author)The integrated surface mass balance (SMB) of the Greenland ice sheet (GrIS) has large interannual variability. Long-term future changes to this variability will affect GrIS dynamics, freshwater fluxes, regional oceanography, and detection of changes in ice volume trends. Here we analyze a simulated 1850–2100 GrIS SMB time series from the...journal article 2014
