[gradsusr] ERA-40 NC template (still doesn't work)

[Ricardo Hallak]

Hi Jose,

pelase, use ncdump to see the strucuture (order of variables) of your files. 
Maybe your ctl is not corresponding to the data order.

More details about the archives I am using include: they are monthly means inside a file named by their respective year, for example: data_1979.nc contains data for the months JAN, FEB,..., DEC, as in the other files (data_1980.nc, data_1981.nc......data_1999.nc). Because of this, my CTL should include monthly time increment, instead years steps.
