[gradsusr] ERA-40 NC template

[Ricardo Hallak]

Dear Jose,

there is something strange in your figures. Looking at them more closely, the
"original" figure shows zonal wind correctly. However, when you use template,
your figure for zonal wind shows values like -10.000, -5.000, or 1.000, 5.000,
etc. There is no variable in your .ctl file which could reach such range.

Could you, if possible, send me one of you nc files? Please, send it directly
to my e-mail, to avoid unnecessary traffic in the internet.
