This directory contains the monthly mean Takahashi 2002 CO2 flux climatology
based on the Wanninkhof parameterization of air-sea gas exchange. Units are
mol/m^2/yr.  The ocean CO2 flux has been extrapolated to cover land regions in
order to prevent errors in the interpolation of coastal grid boxes from
differing land-sea masks.


Instructions for generating taka02_montlhy.bin
==============================================

1 ===> get taka02_montlhy.cdf from
       quercus.igpp.ucla.edu/OceanInversion/inputs/takahashi/

2 ===> generate taka02_montlhy.bin and *_taka02.asc

  % matlab code below requires netcdf toolbox and some other tools
  % that can be obtained by contacting menemenlis@jpl.nasa.gov
  f=netcdf('taka02_montlhy.cdf');
  mo=f{1}(:); lat=f{2}(:); lon=f{3}(:); tmp=f{4}(:);
  dx=[0; diff(lon)]; dy=[0; diff(lat)];
  flux=zeros(length(lon),length(lat),length(mo));
  for i=1:12
   flux(:,:,i)=squeeze(shiftdim(tmp(i,:,:),2));
  end
  clf,contourf(lon,lat,mean(flux,3)',-5:5)
  plotland,caxis([-5 5]),colorbar
  writebin('taka02_montlhy.bin',flux,1);
  fid = fopen('lon_taka02.asc','w');
  fprintf(fid,'%7.3f %7.3f\n',[lon dx]');
  fclose(fid);
  fid = fopen('lat_taka02.asc','w');
  fprintf(fid,'%8.4f %8.4f\n',[lat dy]');
