Dear Jaison, I think your question is of general interest and I am taking the liberty of posting this on the bulletin board. Yes..I had the same feeling that you had about preprocessing. The philosophy of preprocessing files (except for grid_spec) seems to have changed in mom4p0a. In earlier mom4 versions, you were forced to generate preprocessed files where data was interpolated to mom4 (the grid_spec) grid. In mom4p0a, this is no longer necessary. The data_table (which you will find in the input directory of each experiment) has entries which say which variables are to be read from which files (these files do not have to interpolated to grid_spec grid..if they are you say .true. in a particular field which avoids further interpolation. Neither should the variables have fixed particular names..there are entries to map your input field name to the code field name. I think this is a good idea as in mom4_beta2 preprocessing you had to be very careful about the names assigned to interpolated fields and these had to exactly match the names that were hard-coded in ocean_flux.f90). So all the you really have to do is make sure you make the correct grid_spec file and the rest of the work will be taken care of by mom. To carry on with running the test cases, I suggest you download preprocessed data sets from fms.gfdl.noaa.gov and continue.
