[gradsusr] Obtaining total values of a dimension on a netCDF file

[Thiago Veloso]

  Dear Bernd,
  Thanks for your reply.
  After trying the procedure you suggested I received lots of information on display. Each information set corresponding to a specific day.
  For example, setting t 1 3 generates:

  Is this information enough?

sdfopen file.nc
set gxout stats
 
set t 1 32
d var
 
what does that produce?

      Dear GrADS colleagues,
      

        I am working with a netCDF file which contains 
      precipitation values for 31 days. What I am trying to do is to use NCO to 
      obtain the sum of the "time" dimension (thus, the 31 days), but with no 
      success until the present moment.
      

        Could anybody give some directions?
      

        Best regards,
      

        Thiago.
