The following is a description of how the netcdf mapping file
between r05 and gx3v5 grids was produced.

run /fs/cgd/data0/yeager/POP_GRIDS/gx3v5.012/mk_runoff_remap.csh

This generates a 'raw' r05 to gx3v5 mapping, map_r05_to_gx3v5.nc,
and an output /fs/cgd/data0/yeager/POP_GRIDS/gx3v5.012/runoffmap.out
which lists many problem links.

Then, use Yeager's runoff mapping tools to correct/smooth/test
the runoff mapping (see /fs/cgd/data0/yeager/POP_GRIDS/tools/map_runoff/README).
I compiled and ran main.F90 with the following settings:

   file_orig   = '/fs/cgd/data0/yeager/map_r05_to_gx3v5.nc'     ! scripv1.4
   file_corr   =  'r2o.nc'
   file_smooth =  'smoother.nc'
   file_new =   'map_r05_to_gx3v5_roff_e2000r500.nc'
   title = "conservative r05 to gx3v5 runoff map with smoothing"
   efold = 2000000.                             ! efold in meters
   rmax = 500000.

This generated the file map_r05_to_gx3v5_roff_e2000r500.nc, and the output
log /fs/cgd/data0/yeager/POP_GRIDS/gx3v5.012/runoffsmooth.out

cp map_r05_to_gx3v5_roff_e2000r500.nc \
   /fs/cgd/data0/yeager/myinputdata/maps/map_r05_to_gx3v5_e2000r500_030805.nc
