[CF-metadata] scalar coordinate variables

2013-06-13 Thread Jonathan Gregory
r Mark and all As has been discussed in previous emails, David Hassell and I think that interpreting the CF convention requires only the two concepts of (Unidata or dimension) coordinate variables and (CF) auxiliary coordinate variables, whereas scalar coordinate variables are (as the standard

[CF-metadata] percent coverage by GOES-R geophysical variables

Dear Randy You added the following to ticket 102. It's a reasonable point, but I don't think it belongs in that ticket. I suggest we discuss it on the email list. On GOES-R ground, some of the data we report for a given geographic region (i.e. a cell containing many observations) is the

Dear Randy I would favour the use of new standard names with difference_ in them, unless there is such a large number of them that we require something general. Standard name modifiers appear problematic in general, and their intention is to name fields of metadata for a single quantity, which

Dear Seth, I know that I am replying to late in the game to this e-mail from a few weeks ago - sorry about this, but I wanted to make one comment regarding your proposed modification to the definition for CAPE. As you might remember, I recently proposed some new standard names which are

Hi Jonathan, You have good timing; I'm hoping to post updated definitions soon. I'd be happy to adjust the wording to use temperature difference, and leave it unspecified as to the details of whether it's calculated from potential temperature or virtual temperature or whatever. It's similar
