Perennial snow, or firn, covers 80% of the Greenland ice sheet and has the capacity to retain
surface meltwater, influencing the ice sheet mass balance and contribution to sea-level rise …

Models that simulate evolution of polar firn are important for several applications in
glaciology, including converting ice-sheet elevation-change measurements to mass change …

A porous layer of multi-year snow known as firn covers the Greenland-ice-sheet interior. The
firn layer buffers the ice-sheet contribution to sea-level rise by retaining a fraction of summer …

Increasing atmospheric temperatures over ice cover affect surface processes, including melt,
snowfall, and snow density. Here, we present the Surface Mass Balance and Snow on Sea …

Current sea-level rise partly stems from increased surface melting and meltwater runoff from
the Greenland ice sheet. Multi-year snow, also known as firn, covers about 80% of the ice …

Assessing changes in the density of snow and firn is vital to convert volume changes into
mass changes on glaciers and ice sheets. Firn models simulate this process but typically …

Greenland's peripheral glaciers are losing mass at an accelerated rate and are contributing
significantly to sea level rise, but only a few direct observations are available. In this study …

Antarctic surface mass balance (SMB) is largely determined by precipitation over the
continent and subject to regional climate variability related to the Southern Annular Mode …

Surface meltwater can be retained in an ice sheet if it infiltrates the firn and refreezes. This is
an important mass balance process for the Greenland Ice Sheet, reducing meltwater runoff …

The mass balance of the Greenland Ice Sheet (GrIS) in a warming climate is of critical
interest in the context of future sea level rise. Increased melting in the GrIS percolation zone …
