Hi Abhisek,
 
I am not sure if it is a good idea to just interpolate from your 4deg to 1 deg grid. So  one of the sources for your bathymetry and initial conditions could be http://mit.ecco-group.org/cgi-opendap/nph-dods/datasets/ecco_for_las/GECCO/iter23/ . 
 
For monthly salinity forcing data (sss) world ocean atlas 05,09 are good places. For SST , windstress and pretty much anything else the DaSilva site is a good place. Also for Qnet, EmPmR you will need to constrain them . This is also given in the daSilva site. the /global_1x1 gives some indications on how to change from 4deg to 1deg. 
 
Good luck
 
Krishnakumar

Hello Everybody!

I am a newbie to this MITgcm form and also to ocean modeling.

I am a Ph.D. researcher in the field of ocean modeling, particulaly I
wish  to study some oceanic processes through OGCM.

I downloaded MITgcm (63m version) and successfully ran the
"tutorial_global_oce_latlon" given with the code, using MPICH2. Now I
wish to configue the model for 1deg*1deg*30 vertical levels
(360*180*30) for global oceans.

In this regard, I need help to prepared the grid (bathymetry) and
other files (e.g. climatological SST,SST, TAUX, TAUY and initial
files). I have seen the "gendata.m" given for other verification
experiments. Using this I can prepare the Bathymetry file. But I don't
know how to prepare the 3D files (SST,SSS,wind stresses etc.), because
Climatological data (e.g. Levitus Clim) are available with certain
levels.

(1) How to define the vertical levels?
(2) How to interpolate the vertical levels in the Climatological
fields onto my model grid?
(3) How to interpolate monthly fields according to my grid?

I need some Matlab/Fortran scripts in these regards. If anybody has
such scripts, please help me.

(4) What are the Websites where I can get (a) Monthly Levitus
climatology (b) Monthly Wind climatology (c) E-P fields (d) Net
surface heat flux ?

(5) Also let me know which parameters I have to change in the "data"
files in the INPUT directory.

Thanking in advance,
Abhisek, India
