[gradsusr] netcdf file read

[Jeff Duda]

This part of your var entries probably has errors:

  pH2SO4=>ph2so4  25 *28,t,z,y,x* pH2SO4 (the underline and bold portion)

That entry needs to reflect the order in which the array is built in the
netCDF file.  The order can be seen when examining output from ncdump -h
(look at the entry for each particular array).  I'm going to guess that
first integer you have listed should not be there (unless your data has a
fifth dimension that is somehow a function of some other variable such that
it is that different between the different arrays).

If you need further help with this, please send output from ncdump -h on
your file.
