Hi Roy -
I didn't mean to change the 'names themselves', just the order of the
sentences in
some of the new definitions. Sorry if this wasn't clear.
So, for example, the proposed new definition for
sea_surface_swell_wave_to_direction is:
"To_direction" is used in the construction X_to_direction and indicates
the direction towards
which the velocity vector of X is headed. The direction is a bearing in
the usual geographical
sense, measured positive clockwise from due north. Swell waves are the
low frequency portion
of a bimodal wave frequency distribution.
and I am suggesting it be slightly tweaked to:
Swell waves are the low frequency portion of a bimodal wave frequency
distribution.
"To_direction" is used in the construction X_to_direction and indicates
the direction
towards which the velocity vector of X is headed. The direction is a
bearing in the usual
geographical sense, measured positive clockwise from due north.
Is that what you thought I was proposing? It seems like a minor change,
to me. I
don't think it needs to be done to every variable, just the ones that
are being
updated under your proposal and that include a definition of the 'main
term' in
the proposed definition.
Thanks - Nan

Hi Nan,
This goes beyond the scope of the current proposal, covering
many existing Standard Names where I haven't proposed changes to the
definition(I only fixed the real howlers) and all existing
wave Standard Names that include 'sea_surface'. This causes me great
concern as it sets us on a course of entangling a wide-ranging
review of a significant number of additional Standard Name definitions
with the howler fixing and the new names required by Marta and Elodie.
The inevitable result of this course is that it will be months before
we make any progress.
I have also received off-list feedback with wider implications for
Standard Name *definitions*, but not the names themselves concerning
the use of 'due North' and the definitions of 'wind wave' and 'swell
wave'.
Consequently, how about a strategy of considering the three
sub-proposals 'accepted' and getting them published as there is no
remaining controversy over the new names and there is general
agreement that the changed definitions whilst not perfect are
significantly better than what is already there?
Once we've reached that milestone we can then work to produce a
document proposing further improvements to the definitions across all
wave Standard Names resulting in an internally consistent set of
definitions.
Cheers, Roy.

Sub-Proposal
Thanks, Roy, for all your work on this. I have a possibly belated
suggestion,
and one question.
I'd like to suggest that, where we have a definition of the 'main term'
such as
'sea_surface_swell_wave', we just change the order of the sentences in the
definition, with the main term being defined first, which would give us,
for
example,
*sea_surface_swell_wave_from_direction **
**Swell waves are the low frequency portion of a bimodal wave frequency
distribution. **
**"From_direction" is used in the construction X_from_direction and
indicates the direction **
**from which the velocity vector of X is coming. The direction is a
bearing in the usual **
**geographical sense, measured positive clockwise from due north.*
I tried to write this out for each of the definitions below, but the
email message's
formatting got the better of me, and I gave up.
My question is: are we using the term 'sea_surface' in a slightly
different way from other
places it appears in CF, like sea_surface_temperature? That seems to be
a deprecated
alias for skin temperature, and should not have a depth associated with
it. Do we need
to include a description of how this term is used in waves, as part of
these definitions?
Thanks!
Nan
