CDO

I am currently working with ERA5, but I think that this question may be applied to other datasets too.

My issue is that I am trying to select an ERA5 gridbox (of a given variable) in-between the north (or south) pole.

If we consider a gridbox with longitude in-between lon 0deg this can be done easily with cdo sellonlatbox:

cdo sellonlatbox,350,10,30,45 input.nc output.nc

where 350 and 10 are the longitude coordinates crossing lon 0deg.

But how can I select a gridbox ranging from lat 88deg to lat 88deg so that it crosses the north pole (lat 90deg)?

Maybe can I transform the latitude coordinates to 0-180?
I hope to have explained clearly the question.

Thanks for any help
