[CF-metadata] July standard name table update

Dear Alison, dear All,

In June, I raised a topic about the creation of 
wind_from_direction_of_gust.
 From my point of view, it was agreed.

As it was a recent topic, I understand it wasn't in the June update, but 
it also wasn't in the July update.
Any chance for it to be in the September update ?


Best regards

Stéphane

> a. Geoid and reference_ellipsoid names
>
> During the discussion of new names for trac ticket 143 it was agreed that all names referring to 'geoid' or 'reference_ellipsoid'  as the vertical datum should contain the following sentence in their definitions: 'To specify which [geoid | reference ellipsoid] is being used, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention.' This addition affects 10 existing names:
> depth_below_geoid
> geoid_height_above_reference_ellipsoid
> height_above_reference_ellipsoid
> histogram_of_backscattering_ratio_over_height_above_reference_ellipsoid

> square_of_sea_surface_height_above_geoid
>
> b. Air pressure names
>
> During the discussion of new names for trac ticket 143 it was agreed that a definition for 'air_pressure' should be introduced. The definitions of all air_pressure names now contain the following sentence: 'Air pressure is the force per unit area which would be exerted when the moving gas molecules of which the air is composed strike a theoretical surface of any orientation.' This addition affects 17 existing names:
> air_pressure
> air_pressure_anomaly
> air_pressure_at_cloud_base
> air_pressure_at_cloud_top
> air_pressure_at_convective_cloud_base
> air_pressure_at_convective_cloud_top

> c. Global average sea level change
>
> During the recent discussion of the definition of mean_sea_level, it was agreed to also clarify the definition of global_average_sea_level_change. The definitions of all such names now contain the following sentence: "Because global average sea level change quantifies the change in volume of the world ocean, it is not calculated necessarily by considering local changes in mean sea level." This addition affects 6 existing names:
> amplitude_of_global_average_sea_level_change
> global_average_sea_level_change
> global_average_steric_sea_level_change
> global_average_thermosteric_sea_level_change
> phase_of_global_average_sea_level_change
> tendency_of_global_average_sea_level_change

> d. Corrections of typographical errors (reported by Rob Thomas when accessing standard names via the NERC Vocabulary Service)
>
> As a result of obtaining the list of CF standard names via the NERC Vocabulary Service, Rob Thomas of the Irish Marine Institute reported a number of definitions containing unexpected characters such as non-breaking spaces, smart quotes, degree symbols and em and en dashes of varying lengths. None of these characters affect the meaning of the definitions. They have now been either removed or replaced by appropriate ascii characters. The following 28 names are affected:
> automated_tropical_cyclone_forecasting_system_storm_identifier
> downward_air_velocity
> land_ice_basal_specific_mass_balance_flux
> atmosphere_absorption_optical_thickness_due_to_sea_salt_ambient_aerosol_particles

> In addition to correcting some typographical errors, as described in 3d, the sentence 'The surface called "surface" means the lower boundary of the atmosphere' was removed from three existing sea_surface temperature names, a change that was requested by Craig Donlon in 2016.
