Suggestion 'presence_of_surface_snow' should have been 'presence_of_surface_snow_cover' to maintain consistency.... ________________________________________ From: CF-metadata [[email protected]] On Behalf Of Lowry, Roy K.

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. ________________________________________ From: CF-metadata [[email protected]] On Behalf Of Ute Brönner [[email protected]] Sent: 05 September 2012 18:40 To: Jim Biard Cc: Heather Brown; Raymond Nepstad; [email protected]; Alisa Young 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 Am 05.09.2012 um 18:31 schrieb "Jim Biard" <[email protected]<mailto:[email protected]>>: 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.
