Welcometo the Ice Sheet System Model (ISSM) website. ISSM is the result of a collaboration between the Jet Propulsion Laboratory and University of California at Irvine. Its purpose is to tackle the challenge of modeling the evolution of the polar ice caps in Greenland and Antarctica.
ISSM is open source and is funded by the NASA Cryosphere, IceBridge Research and MAP (Modeling Analysis and Prediction) programs, JPL R&TD (Research, Technology and Development) and the National Science Foundation. Our main collaborators are: MSSMat Laboratory of École Centrale Paris, Argonne National Laboratory and the Department of Geology of University of Buffalo, NY.
As synthesized in the last Intergovernmental Panel on Climate Change (IPCC) Assessment Report AR5, "significant uncertainties remain, particularly related to the magnitude and rate of the ice-sheet contribution for the 21st century and beyond".
To remedy this problem, large scale ice flow models are necessary that can accurately model the evolution of Greenland and Antarctica in a warming climate. In order to achieve this goal, and improve projections of future sea level rise, ISSM relies on state of the art technologies. These include:
