Revisiting Trends in Greenland Ice Sheet Albedo Using the Combined MODIS and VIIRS Record

Earth and Space Science
The MODerate resolution Imaging Spectroradiometer (MODIS) instruments onboard NASA's Aqua and Terra satellites have been used to monitor trends in Greenland Ice Sheet albedo for over two decades.

Jökulhlaup Observed at Greenland Ice Sheet

Eos, Transactions American Geophysical Union, 2008
On 31 August 2007, about 35 kilometers upstream from the town of Kangerlussuaq, in western Greenland, a roughly 0.5‐square‐kilometer permanently ice‐dammed lake on the northern flank of the Russell Glacier—an outlet glacier of the Greenland Ice Sheet—suddenly broke free and drained into the Watson River (Figure 1).

Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

A Greenland-wide empirical reconstruction of paleo ice sheet retreat informed by ice extent markers: PaleoGrIS version 1.0 [PDF]

Climate of the Past
The Greenland Ice Sheet is a large contributor to global sea level rise, and current mass losses are projected to accelerate. However, model projections of future ice sheet evolution are limited by the fact that the ice sheet is not in equilibrium with ...

A Sea‐Ice‐Enhanced KPP Parameterization: Impacts on AMOC Simulation and Physical Pathways

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract This study presents a sea‐ice‐enhanced K‐profile parameterization to improve simulations of the Atlantic Meridional Overturning Circulation (AMOC) in ocean–sea ice coupled models. The modified KPP dynamically scales the background vertical diffusivity with local sea‐ice fraction, representing the insulating and turbulence‐suppressing effects ...

Constraining the geothermal heat flux in Greenland at regions of radar-detected basal water

Journal of Glaciology, 2019
The spatial distribution of basal water critically impacts the evolution of ice sheets. Current estimates of basal water distribution beneath the Greenland Ice Sheet (GrIS) contain large uncertainties due to poorly constrained boundary conditions ...

Chemistry of Greenland Ice Sheet studied

Eos, Transactions American Geophysical Union, 1991
The first ice coring project to include a major emphasis on the study of atmospheric processes and changes in the Greenland Ice Sheet that influence the chemistry of the ice core began in April of this year under the auspices of the Greenland Ice Sheet Project Two (GISP2).

Influence of Atmospheric Rivers on Lake Ice Phenology in the Northern Hemisphere

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Atmospheric rivers (ARs) can rapidly alter regional hydrothermal conditions and directly affect lake ice. This study presents the first assessment of AR impacts on lake ice phenology across the Northern Hemisphere. AR events were associated with positive anomalies in temperature, rainfall, and snowfall, as well as negative anomalies in solar ...

Chemical species spatial distribution and relationship to elevation and snow accumulation rate over the Greenland Ice Sheet [PDF]

, 1996
Major chemical species (Cl−, NO−3, SO2−4, Na+, K+, Mg2+, Ca2+) from 24 snowpits (sampled at a resolution of 3 cm, total 2995 samples) collected from northern, central, and southern Greenland were used for this investigation.
