Nancy,

    /home/blackforest/hecht/data_gx1v2/shf_320x384.da
is actually a link to file that is no longer there. I still have this file 
as 
    mss:/HECHT/POP/AUX/gx1v2/shf_320x384.da
It shouldn't matter that gx1v2 files are still being used, as the fields 
are not masked, and the horizontal grid has not changed.

I haven't found a readme, but I did find some scattered notes. On 17 Nov 
2000 I emailed Frank that I had just done interpolations to the gx1 grid. 
I used scrip to produce mapping files. The grid files and resulting maps 
are in
        mss:/HECHT/pop/320x384/remap
files
        GP_x1p_masked_20001117.nc
        GP_x1p_unmasked_20001117.nc
        remap_grid.T62.nc
        remap_grid.ll1deg.nc
        remap_grid.ll2deg.nc
        rmp_unmasked_1x1_to_POP_320x384.nc
        rmp_unmasked_2x2_to_POP_320x384.nc
        rmp_unmasked_POP_320x384_to_1x1.nc
        rmp_unmasked_POP_320x384_to_2x2.nc
        rmp_unmasked_POP_320x384_to_T62.nc
        rmp_unmasked_T62_to_POP_320x384.nc 

I got the input data from Julianna, who did similar interpolations for the 
older 384x320 grid. Here is an email from her describing the preparation 
of that data.

Frank and Matthew,

The following is an account of the setup of PG1 data and model run.

Julianna

===========================================================================

PG1 : 384x320x40  /fs/cgd/data0/jcc/pop/PG1/data
                  /JCC/POP/GLOBAL/run_384x320x40/AUX
                                                /INIT
                                                /remap


      o   grid data and kmt from /data/tcraig/_aux0_/pcm2/ocn_grid

              kmtn.384x320x40.dat.da  09/01 version
              grid.384x320x40.merge.da


      o   surface forcing data : interpolated using SCRIP from dataset

                                 /KAUFF/csm/data/ocn_force/data_orig.tar

          source codes in /fs/cgd/data0/jcc/pop/rds_grid/SCRIP


      o   initial data : interpolated from January Levitus data

          source codes in /fs/cgd/data0/jcc/pop/rds_grid/lev_interp
                                                        /rewrite/PG1

      o   model source code (in the order of) :

          1)  /fs/cgd/data0/jcc/tarfile/pop_1.2/source/*

          2)  /fs/cgd/home0/csmocean/Source/POP_MOD/1.2/netcdf/*
              also in /fs/cgd/data0/jcc/tarfile/pop_1.2/netcdf_mods

          3)  /fs/cgd/home0/gokhan/upperocean/pop_mods_v1.2.d
 
              hmix_aniso.F
              horizontal_mix.F

              /fs/cgd/home0/gokhan/upperocean/x3_prime_pop.d/G03p-3.12/ocn/source_mods
           
              hmix_gm.F
              vmix_kpp.F

              also in /fs/cgd/data0/jcc/tarfile/pop_1.2/mixing_mods
              pop_in : see gokhan_8-25, extra list for &hmix_gm_nml and &vmix_kpp_nml

          4)  ***use the 4 *.F files from Rick in 
              in   /fs/cgd/data0/jcc/tarfile/pop_1.2/rds_mods

      o   pop_in : from Rick

      o   time_steps used by Rick

                 fullsteps_per_day = 48 for 40 days
                 fullsteps_per_day = 24 for 40 days
                 fullsteps_per_day = 12 for 40 days
                 fullsteps_per_day = 8 for remainder of run

                 this is with dtuxcel = 0.2.

                 You should, in principle, be able to get by with
                 something like twice the timestep I used.  Shoot
                 for 4 or 5 steps/day after the initial spinup.

      o   On blackforest

          /home/jcc/PG1/source
 
                 tavg.F different, added level mean T.S to tavg.*.hdr file

          /ptmp/jcc/PG1/001


      o   output in /fs/cgd/data0/jcc/pop/PG1/001
                    /JCC/POP/GLOBAL/run_384x320x40/PG1-001

                 1 month run (64 procs) : 744 steps
                                          24 (22+2) total steps per day
                                          dtt        = 3756.52 seconds
                                          total time =  891.16 seconds

                 diagnostics every 5 days
