= 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






July 15 DRDF meeting

Michael has two ongoing integrations
with perpetual high SAM and perpetual low SAM, respectively.
http://ecco2.jpl.nasa.gov/data1/meeting/ISSM-ECCO2/samforcing_mps.ppt

- science action items

  Michael will provide a lat/lon grid of
  melting rate on 1-km PIG grid.

  There is going to be some incompatibility
  in the location of the shelf and grounding
  line, initially.  That's OK, just set to
  zero anywhere where there is a mismatch.

  ISSM team will run something and provide
  with a time series of ice shelf thicknesses.
  ISSM will also provide ECCO2 with grounding line.

  DM will apply these to a regional PIG domain ...

- technical action items

  give you the 5km and the 1km grid
  and you will start thinking about 
  mapping modules between the two grids

request accounts for trac for Michael and Dimitris
so we can access wiki

next meeting jul 23 - DM will check ORSL availability and email
