[MASK]: Antarctic Ice Sheet Modeling using ISSM

[hseroussi]

Overview

• Product name and version: Antarctic simulations with ISSM
• Purpose of your product: Past and future projections of Antarctic evolution
• Geographic region: Antarctic ice sheet with connected ice shelves and peripheral glaciers
• Year(s) covered by product: 2007-2300

Upstream

• What upstream mask product did you use?
  BedMachine Antarctica for regions covered by ice, ice thickness, surface elevation and bedrock elevation: https://doi.org/10.1038/s41561-019-0510-8

• Reason for using this mask
  Comprehensive and consistent dataset of ice geometry

• If you modified the upstream mask, for example, to define and split ‘main’ vs. ‘peripheral’, how and why?
  N/A

• Effort required by you if upstream product changed (to a community standard)
  Changes in geometry require redoing all the model inialization process (data assimilation, etc.). We do this regularly so effort is limited if dataset includes comprehensive and consistent geometry.

• If you used internal basins, which product and why?
  Internal basins are not used for the simulations but afterwards to compute regional metrics

• If you subset to a geographical region (Greenland, Antarctica, sub-region, peripheral, individual glacier), how and why
  We use all Antarctic regions covered by ice reported in BedMachine Antarctica

• Type: raster

• Resolution if raster: BedMachine Antarctica is 500 m, model resolution varies between 500 m around grounding lines and in shear margins to 20 km inland

• Projection information: EPSG 3031

• Year or years of input product(s): 2007-2300

Other notes

Ice sheet models typically include all glaciated areas on the continent, connected ice shelves and peripheral glaciers that may or may not interact with the main ice sheet.
