Hello Evan, Opinion on this is divided - some communities have decided to regard the Standard Name as mandatory. The CF Conventions state that the Standard Name may be omitted providing that the Long Name is supplied. In my view (automated data aggregation) in your case I would use the Long Name to describe each navigation stream and the Standard Names to label the primary navigation stream.
Cheers, Roy. ________________________________________ From: Manning, Evan M (398B) [evan.m.mann...@jpl.nasa.gov] Sent: 30 March 2015 00:33 To: cf-metadata@cgd.ucar.edu Subject: [CF-metadata] Using a standard_name more than once in a file I'm defining a data set, and I have a question about reusing standard_names in a file. For example this a swath, so there a lat/lon/time for each observed spot. There is also a subsatellite lat/lon and mid-scan time. And in some cases I have separate lat/lon by MW band. So, does every lat get standard_name set to latitude, or just the primary one? On the one hand, I can see that users of each field could benefit from having the standard_name set so that users of that field know what it is. But on the other hand, if a user or program wants to come in and see what is "the" latitude, maybe things work better if the standard_name latitude is only used once? (Latitude is a key geolocation parameter. Does the answer to the above question change if we're talking about something less foundational, like land_area_fraction or sensor_view_angle?) On a related topic, I see that adding standard_names platform_latitude, etc. has been discussed but the discussion seems to be stalled. What are the prospects?
