Hi All, An extra bit of info on this. The trac and mailman lists are indeed independent. They are synchronized by hand. As moderator of the cf-metadata mailman list I keep a list of new subscriptions and removals from the list and every now and then I forward that list to folks at PCMDI. So

Re: [CF-metadata] On scalar coordinate variables

2015-12-09 Thread Brian Eaton
Hi Martin and David, When I was writing about scalar coordinate variables in the CF convention, I considered a scalar to be a zero dimensional object. That is distinct from a 1 dimensional array which happens to only have 1 component. A coordinate array in the NUG sense is a one dimensional

All, Our sys admins have informed me that a mailman software upgrade has changed the URL. The archive is now at http://mailman.cgd.ucar.edu/mailman/private/cf-metadata/. The cfconventions.org site will need to update this link. I found that accessing the archive required me to enter a password

Hi John, Thanks for your comments. I completely agree. The archive should be public, and if its URL does change then we should deal with the redirect here. I've spoken with admins here and made these requirements known. Apparently this last mailman upgrade caused plenty of headaches, so we

Re: [CF-metadata] Using add_offset scale_factor with coordinate variables

2012-04-12 Thread Brian Eaton
I agree with Heiko's comment. Jonathan, are you thinking that CF disallows packing of coordinates because we neglected to explicitly include them in Table A.1? I think this was just an oversight. I don't have any recollection that we intended to disallow packing coordinates, and I don't find

Hi All, I don't believe there was ever an intention to disallow missing values from auxiliary coordinate variables. First, note that the definition of an auxiliary coordinate variable in section 1.2 makes no mention of this while it is explicit in the definition of a coordinate variable that

Hi John, You might have a look at the ESMF time handling utilies for some ideas about what a library that supports modelling (i.e., non-standard calendars) contains. http://www.earthsystemmodeling.org/esmf_releases/public/last/ESMF_refdoc/ Brian On Fri, Apr 01, 2011 at 05:04:42AM -0600, John

Re: [CF-metadata] CF Standards

The checker also didn't recognize that the a and b variables are being used to describe a dimensionless vertical coordinate. So I'm wondering whether the coordinate variable, lev(lev), has the standard_name and formula_terms attributes that should allow the checker to recognize them. Brian On

Hi Karl, The discussion concerning the introduction of the scalar coordinate variable is available in the archive (July 2003 under the subject size-one axes). There was never a decision to disallow the bounds attribute. Although it could be more explicitly stated in the current document, I

Hi Jonathan, I'm wondering about this statement: I don't think it's misleading. This is a consistent rule in CF standard names: quantities with different canonical units must have different standard names. Isn't the use of cell_methods with a value of variance an example where we don't
