'abstract': (
"""Citation publication abstract: In recent decades, meltwater
runoff has accelerated to become the dominant mechanism for mass
loss in the Greenland ice sheet. In Greenland’s high-elevation
interior, porous snow and firn accumulate; these can absorb surface
meltwater and inhibit runoff, but this buffering effect is limited
if enough water refreezes near the surface to restrict percolation.
However, the influence of refreezing on runoff from Greenland
remains largely unquantified. Here we use firn cores, radar
observations and regional climate models to show that recent
increases in meltwater have resulted in the formation of
metres-thick, low-permeability ‘ice slabs’ that have expanded the
Greenland ice sheet’s total runoff area by 26 ± 3 per cent since
2001. Although runoff from the top of ice slabs has added less than
one millimetre to global sea-level rise so far, this contribution
will grow substantially as ice slabs expand inland in a warming
climate. Runoff over ice slabs is set to contribute 7 to 33
millimetres and 17 to 74 millimetres to global sea-level rise by
2100 under moderate- and high-emissions scenarios,
respectively—approximately double the estimated runoff from
Greenland’s high-elevation interior, as predicted by surface mass
balance models without ice slabs. Ice slabs will have an important
role in enhancing surface meltwater feedback processes,
fundamentally altering the ice sheet’s present and future
hydrology."""

("""The Regional Atmospheric Climate Model (RACMO) data included use
a new run at 5.5-km horizontal resolution of the polar (p) version
of RACMO2.3p2 for the period 1958–2017. RACMO2.3p2 incorporates the
dynamical core of the High Resolution Limited Area Model and the
physics from the European Centre for Medium-Range Weather
Forecasts–Integrated Forecast System (ECMWF-IFS cycle CY33r1).
RACMO2.3p2 includes a multilayer snow module that simulates melt,
water percolation, and retention in snow, refreezing, and runoff.
The model also accounts for dry snow densification, and drifting
snow erosion and sublimation. Snow albedo is calculated on the basis
of snow grain size, cloud optical thickness, solar zenith angle, and
impurity concentration in snow. As compared to the model described
in Noel et al. (2018) (reference below), no model physics have been
changed. However, increased horizontal resolution of the host model,
i.e., 5.5 km instead of 11 km, better resolves gradients in SMB
components over the topographically complex ice sheet margins and
neighboring peripheral glaciers and ice caps. Some data output has
also been downscaled to 1-km resolution. QGreenland currently
displays data that describes annual mean values over 1958-2019 for
wind speed, total precipitation, snowfall, snowmelt, runoff,
sublication, snow drift erosion, and 2-m temperature. Input
topography data is also included, along with the PROMICE ice mask
and grounded ice mask.

("""Citation publication abstract: The Greenland Ice Sheet holds
around 7.2 meters of sea-level equivalent. In recent decades rising
atmosphere and ocean temperatures have led to an acceleration in
mass loss, adding an average of about 0.5 millimeters per year to
global mean sea-level between 1991 and 2015. Current ice margin
recession in Greenland is led by the retreat of outlet glaciers, the
large rivers of ice ending in narrow fjords that drain the ice sheet
interior. Recent progress in measuring ice thickness is enabling
models to reproduce the complex flow patterns found in outlet
glaciers, a key step towards realistic projections. Here we pair an
outlet glacier resolving ice sheet model with a comprehensive
uncertainty quantification to estimate Greenland's contribution to
sea-level over the next millennium under different climate forcings.
We find that Greenland could contribute 5-33 centimeters to
sea-level by 2100 and 11-155 centimeters by 2200, with discharge
from outlet glaciers contributing 6-45% of the total mass loss. Our
analysis shows that uncertainties in projecting mass loss are
dominated by uncertainties in climate scenarios and surface
processes, followed by ice dynamics, whereas uncertainties in ocean
conditions play a minor role, particularly in the long term. We
project that Greenland will very likely become ice-free within a
millennium without significant reductions in greenhouse gas
emissions.
This dataset compilation contains the simulations for the manuscript
"Contribution of the Greenland Ice Sheet to sea-level over the next
millennium" prepared with the Parallel Ice Sheet Model (PISM).
This dataset provides the likelihood of a pixel being ice covered at
the year 3007 for the RCPs (Representative Concentration Pathways)

"""Abstract for reference publication: Each summer, surface melting
of the margin of the Greenland Ice Sheet exposes a distinctive
visible stratigraphy that is related to past variability in
subaerial dust deposition across the accumulation zone and
subsequent ice flow toward the margin. Here we map this surface
stratigraphy along the northern margin of the ice sheet using
mosaicked Sentinel-2 multispectral satellite imagery from the end of
the 2019 melt season and finer-resolution WorldView-2/3 imagery for
smaller regions of interest. We trace three distinct transitions in
apparent dust concentration and the top of a darker basal layer. The
three dust transitions have been identified previously as
representing late-Pleistocene climatic transitions, allowing us to
develop a coarse margin chronostratigraphy for northern Greenland.
Substantial folding of late-Pleistocene stratigraphy is observed but
uncommon. The oldest conformal surface-exposed ice in northern
Greenland is likely located adjacent to Warming Land and may be up
to ~55 thousand years old. Basal ice is commonly exposed hundreds of
metres from the ice margin and may indicate a widespread frozen
basal thermal state. We conclude that the ice margin across northern
Greenland offers multiple opportunities to recover paleoclimatically
distinct ice relative to previously studied regions in southwestern
Greenland.
