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.
