Dear All,
It's becoming clear that we need a Standard Name component to cover boolean values whose trigger point may then be specified elsewhere as Jonathan stated. In the biological domain, the syntax 'presence_of_x' where x is a taxon name is often used. Could this be adopted giving the Standard Name 'presence_of_surface_snow' for Jim and opening the door for a raft of Standard Names to cover Ute's use case?
Cheers, Roy.

Subject: Re: [CF-metadata] Proposal for standard name "snow_cover_binary_mask"
Hei,
Wouldn't that feature come in handy for other grids as well where we would like to mark sth. like "exposed" or "not exposed"? So I would suggest to make it snow independent.
Regards,
Ute

Hi.
I'd like to propose the new standard name "snow_cover_binary_mask". There is a NOAA snow coverage extent product that is being put into netCDF format. The product is derived from the IMS Daily Northern Hemisphere Snow & Ice Analysis. It is a grid in which cells are marked as snow-covered or not snow-covered. The GCMD already has the keywords "Cryosphere > Snow/Ice > Snow Cover" and "Terrestrial Hydrosphere > Snow/Ice > Snow Cover", which are applied to the source product.
In this particular product, grid cells are marked as snow-covered when > 42% of the cell indicates the presence of snow.
I'd appreciate any thoughts or comments.
Grace and peace,
Jim
