Re: [CF-metadata] Standard name for land/sea mask

2017-07-11 Thread Jonathan Gregory
Dear Jim I agree that for some purposes you want a field of integers that identifies the area types, rather than a binary mask. I think this can be achieved by using the existing standard_name of area_type. This standard_name indicates a string- valued data variable, but it can be encoded as

2017-07-11 Thread Elodie Fernandez
