[MITgcm-support] input files for regional model

[Menemenlis, Dimitris (3248)]

For lat/lon gid, you don't need any grid information files.
You specify everything in runtime parameter file "data"
See, for example, MITgcm/verification/lab_sea/input/data

 &PARM04
 usingSphericalPolarGrid=.TRUE.,
 delX=20*2.E0,
 delY=16*2.E0,
 delZ= 10., 10., 15., 20., 20., 25., 35., 50., 75.,
       100., 150., 200., 275., 350., 415., 450.,
       500., 500., 500., 500., 500., 500., 500.,
 ygOrigin=46.,
 xgOrigin=280.,
 rSphere = 6371.D3,

Hi there

I'm attempting to modify the Arctic regional model described here...

http://mitgcm.org/viewvc/MITgcm/MITgcm_contrib/arctic/cs_36km/readme.txt
http://ecco2.jpl.nasa.gov/data1/arctic/run_template2/README_arctic2.txt

My question is regarding the coordinate system. The Arctic model uses "usingCurvilinearGrid=.TRUE.," in the data input file but I want to use a regular latitude-longitude grid ("usingCartesianGrid=.TRUE.").

When I do this, do I also need all of the many other input files needed (LATC.bin, LONC.bin, RA.bin, RAW.bin etc etc)?

If I don't need these files, then whereabouts do I specify information regarding the grid system?

Many thanks :)

Jonny
