This directory contains the model region masks that should be used for 
the ocean inversions.  Regions have been labeled with numbers 1-9 or letters.  

30reg_regionmask.bin: Defines the 29 ocean model regions that should be used
for the ocean inversion. 

Instructions for generating 30reg_regionmask.bin
================================================

1 ===> get 30reg_regionmask.cdf from
       quercus.igpp.ucla.edu/OceanInversion/inputs/region_mask/

2 ===> get the appropriate netcdf.inc and libnetcdf.a files
       from www.unidata.ucar.edu/packages/netcdf/
  on nireas:
  cp ~dimitri/software/netcdf/netcdf-3.5.0/include/netcdf.inc .
  cp ~dimitri/software/netcdf/netcdf-3.5.0/lib/libnetcdf.a .

3 ===> compile and run read_mask.f
  f77 -o read_mask.x read_mask.f -L. -lnetcdf
  read_mask.x

4 ===> use matlab script mk_30reg_bin.m to generate
       30reg_regionmask.bin and *_regionmask.asc
  matlab
  mk_30reg_bin
