Dear Jonathan,
I'll leave it to Andy to explain 'without tide' from a modelling perspective -
I can guess what they do but could be wrong. In NOC we measure and report the
sea surface elevation relative to a datum - Lowest Astronomical Tide - but we
then subtract the elevation relative to
Dear Jonathon,
Possibly, I have been over-thinking this! I went back to square one and looked
at the family of 'sea_surface_height' variables again and read the phrasing as
carefully as I could.
From these:
'sea_surface_height' is a time-varying quantity - so implies a generic
summation of

Hi Andy,
A thought that struck me as I read through your e-mail is that surges aren't
the only meteorological forcing. Whilst in a model the non-tide contributions
can be easily differentiated in observational data they cannot.
Would 'sea_surface_height_due_to_meteorological_forcing' be a
Hi again,
Having read a bit more I see that 'surge' is commonly used to cover the total
forcing due to wind and pressure so ignore my previous comment!
Cheers, Roy.

Hi all,
As many of you know, the 2018 netCDF-CF Workshop [1] will be on 19-20 June
2018 at the University of Reading in the UK. This workshop will focus on
efforts to advance the Climate and Forecast (CF) metadata conventions for
netCDF (netCDF-CF). The meeting is being hosted by the National
Dear Andy
Yes, I agree, that is a sufficiently different quantity that it can't clearly
be seen as a statistic describable by cell_methods and so needs its own name.
Maybe you could add something more to the definition.
Best wishes and thanks
Jonathan

Thanks Jonathon,
Re the directional_spread parameters in section 4, the "one-sided directional
width" as its described in Holthuijsen's book (Waves in Oceanic and Coastal
Waters) is perhaps more precisely defined by Tucker and Pitt (Waves in Ocean
Engineering) as "half the beam-width as
