CDO

Thanks so much for all your incredible work developing CDO.

I'm fairly inexperienced with netcdf data, but isn't there some quick way to change the latitude increment for zonal mean datasets ? I have a file containing zonal mean T data at 4 degree lat intervals, and for various reasons I want to convert these data to coarser res, say 5 or even 10 deg lat intervals. I tried doing this with CDO remap* but looks like it can't accept zonal mean data for input. I thought there's some simple way to do this with NCO/CDO, but after wasting hours fiddling with CDO remap* and ncwa I don't see the answer -- very frustrating! I'd really appreciate any help that anyone here could give.

If there's no way to do this with CDO/NCO, I assume it's best to take area-weighted means of the original data, then binning into desired res intervals (right?) Is there some simple way to do this latter task with CDO/NCO? I don't see a way to select lat slices in a zonal mean dataset??

Thank you so much in advance for any suggestions you could give!
