[gradsusr] GrADS Loop Help

[Martin V. Mathew]

Hi Emily

The script was missing one line to increment the variable 'yrs'. Now i
have included that in the script.
I have attached two scripts with this mail. Of these, I have tested the
second one and it is found to yield the desired result. I think you can fix
any other potential error by cross checking both the scripts. You can use
file 'taux_tropflux_1d_1979_2012.nc' from the following URL to run the
second script.
