ISSM/ECCO2 coupling work plan

Science question

• Sensitivity to SAM will be computed from CS510 ocean-only 10 years of hi-SAM vs 10 years of low SAM
• Provide Pine Island Glacier domain boundary conditions ocean ~1-1.5 km PIG domain to match ISSM

Implementation

SCRIPT to make ISSM and MITgcm talk to each other by sharing files (format: binary)

Coupling algorithm

• Initial cavity
• Run MITgcm for a month -> send melt rate and other results to ISSM
• Run ISSM for this same month -> send the basal temperature, new cavity geometry, ... to MITgcm
• Iterate for about 10 years

The two models would be run sequentially for now.

work plan

• Menemenlis/Schodlok
  • send instruction how to run MITgcm
  • finish PIG
  • sort out shelf-ice package
  • baseline global integration with JRA25
  • 10-year hi-SAM on CS510
  • 10-year lo-SAM on CS510
  • provide our PIG grid to ISSM

• ISSM team
  • write a module to interpolate/write ice thickness on the ocean PIG grid
  • write module to read/interpolate heat flux and melt rate from ocean solution on PIG grid to ISSM grid
