downloading and visualizing NARR data

[Jin-Ho Yoon]

Dear Alan,

The way i use NARR data is to regrid it first onto a lat-lon coordinate
using regrid2.  Somehow grib format and projection do not work well
at the beginning.  The following is to 1x1 grid using 'fwrite' command.
You have to make the ctl file matching this new format.

  'temp=regrid2('var',1.0,1.0,vt_p1,0.5,0.5,-210.5,8.0)'
  'set gxout fwrite'
  'set lat 8.0 90.0'
  'set lon -210.5 -0.5'
  'd temp'
  'close 1'
