Dear Dirk
For these quantities I believe you can use the existing standard names of
sea_ice_area, volume and extent. To specify the area over which the integral
applies, you can supply size-1 coordinate variables or scalar coordinate
variables, with bounds, for latitude and longitude. For the entire hemispheres
I suppose longitude is not needed, and it would be sufficient to supply
latitude coordinates with bounds of -90,0 and 0,90 degN.
Best wishes
Jonathan
