Modeling the Greenland englacial stratigraphy [PDF]
The Cryosphere, 2021 Radar reflections from the interior of the Greenland ice sheet contain a comprehensive archive of past accumulation rates, ice dynamics, and basal melting. Combining these data with dynamic ice sheet models may greatly aid model calibration, improve past

initMIP-Antarctica: an ice sheet model initialization experiment of ISMIP6
The Cryosphere, 2017 . Ice sheet numerical modeling is an important tool to estimate the dynamic contribution of the Antarctic ice sheet to sea level rise over the coming centuries. The influence of initial conditions on ice sheet model simulations, however, is still unclear.

The Cryosphere, 2021 . The Antarctic Ice Sheet will play a crucial role in the evolution of global mean sea-level as the climate warms. An interactively coupled climate and ice sheet model is needed to understand the impacts of ice—climate feedbacks during this evolution ...

Observing and Modeling Ice Sheet Surface Mass Balance [PDF]
Reviews of Geophysics, 2019 AbstractSurface mass balance (SMB) provides mass input to the surface of the Antarctic and Greenland Ice Sheets and therefore comprises an important control on ice sheet mass balance and resulting contribution to global sea level change. As ice sheet SMB varies highly across multiple scales of space (meters to hundreds of kilometers) and time (hourly ...

Climatic Conditions for modelling the Northern Hemisphere ice sheets throughout the ice age cycle [PDF]
Climate of the Past, 2007 The ice sheet-climate interaction as well as the climatic response to orbital parameters and atmospheric CO<sub>2</sub> concentration are examined in order to drive an ice sheet model throughout an ice age cycle.

Description and validation of the ice-sheet model Yelmo (version 1.0)
Geoscientific Model Development, 2019 . We describe the physics and features of the ice-sheet model Yelmo, an open-source project intended for collaborative development. Yelmo is a thermomechanical model, solving for the coupled velocity and temperature solutions of an ice sheet ...

Modelling landscape evolution under ice sheets [PDF]
Geomorphology, 2008 We use an ice sheet model (GLIMMER) with an erosion component to examine the evolution of landscapes under ice sheets over long time scales in hypothetical situations. GLIMMER is a fully coupled thermomechanical 3-dimensional ice sheet model with a sliding component.

Geoscientific Model Development, 2019 . Providing reliable projections of the ice sheet contribution to future sea-level rise has become one of the main challenges of the ice sheet modelling community. To increase confidence in future projections, a good knowledge of the present-day state of

The Glimmer community ice sheet model [PDF]
Journal of Geophysical Research: Earth Surface, 2009 We present a detailed description of the Glimmer ice sheet model, comprising the physics represented in the model and the numerical techniques used. Established methods are combined with good software design to yield an adaptable and widely applicable model. A flexible framework for coupling Glimmer to global climate forcing is also described.
