= 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 wikihttp://s383-rhat/trac/issm/wiki/ISSM-ECCO2

 * Next meeting jul 23 - DM will check ORSL availability and email


== July 23 DRDF meeting ==

 * Michael has generated melting rates and heat fluxes on CS510
 - They are here:
http://ecco2.jpl.nasa.gov/data1/meeting/ISSM-ECCO2/
 -Need to interpolate to lat/lon grid - DM
 - I will put in same place and provide interpolation script.
