[netcdfgroup] delete colapsed dimension

[Tiago Silva <tiagoams@xxxxxxxxxxx>]

Hi
 
How can I delete a dimension of length 1 from an netcdf file using NCO tools?
This is the initial part of the ncdump of one of my files and I want to 
elliminate lonc:
 
dimensions:
        time = 744 ;
        nbdyp = UNLIMITED ; // (102 currently)
        lonc = 1 ;
variables:
        float elev(nbdyp, time, lonc) ;
(...)
 
I am using NCO 4.0.5.
 
Thanks,
Tiago
