[gradsusr] Decoding ECMWF Data

[Mohsen Soltani]

Hello Andrew,

I examined your ctl. and found that the only thing you need to do is to
change a number from 2 into 3 in the ctl file!
*****************
that is:
Uprs 2 131,100,0 ** (profile) U velocity [m s**-1]
should be changed into:
Uprs 3 131,100,0 ** (profile) U velocity [m s**-1]
***********************************************
And then you will be able to display "uprs" in both 850-hPa and 500-hPa
levels. Therefore, do as follows:
*******************
open .....ctl
set lev 850
d uprs
c
set lev 500
d uprs
************************
The attached are the outputs of each level.
