Dear ferret_users,
         I wanted to average the data of every two consecutive time points. For example, I want to average Jan-Feb, Mar-Apr, May-Jun, Jul-Aug, Sep-Oct etc.,. in monthly_navy_winds climatological dataset.
I tried using the ferret command:
yes? list/x=87/y=15 uwnd[l=1:12:2@ave]
but the list output averaged value is wrong (of course, i might be used list command improperly) when compared with the calculated one. Please let me know, how can i do the same with @ave.

regards,
- paul.
