- Working Groups
The primary objectives of the Land Ice Working Group (LIWG) are (1) to couple a well validated, fully dynamical ice sheet model to the CESM, and (2) to determine the likely range of decade-to-century-scale sea-level rise associated with the loss of land ice.
The ice sheet model will initially be the open-source Glimmer model, but efforts are underway to improve its dynamical core. This enhanced ice sheet model will be referred to as the Community Ice Sheet Model (CISM) and will function in both standalone and coupled modes. CISM modeling activities will include the large-scale simulation of the Greenland and Antarctic ice sheets, as well as finer-resolution modeling of mountain glaciers, ice caps, and outlet glaciers with the potential to alter sea level.
To better understand interactions between ice sheets and other parts of the climate system, the LIWG interacts closely with other working groups, including the Climate Change, Land Model, Ocean Model, Polar Climate, and Paleoclimate groups. Like other working groups, the LIWG meets twice a year: once at the annual CESM workshop in June and once during the winter.
