[CF-metadata] Standard name table - August and September updates

From: Alison Pamment - UKRI STFC <alison.pamment>

Dear All,

The standard name table was updated on 7th August to version 58 and has now been updated again to version 59, dated 25th September 2018. Details of both updates are listed at the end of this message. All changes have also been published in the NERC Vocabulary Server.

Andrew Saulter has been added to the list of standard name table contributors: http://cfconventions.org/Data/cf-standard-names/docs/standard-name-contributors.html.

The September update contains just a few names. However, there has been good progress in the discussion of the platform orientation names (yaw, pitch, etc.) and I expect we will be able to finalize them in time for the next update, planned for 16th October.

Best wishes,
Alison

sea_surface_secondary_swell_wave_period_at_variance_spectral_density_maximum 
sea_surface_tertiary_swell_wave_directional_spread 
sea_surface_tertiary_swell_wave_energy_at_variance_spectral_density_maximum 
sea_surface_tertiary_swell_wave_from_direction 
sea_surface_tertiary_swell_wave_mean_period 
sea_surface_tertiary_swell_wave_period_at_variance_spectral_density_maximum 
sea_surface_tertiary_swell_wave_significant_height 
sea_surface_wave_directional_spread 
sea_surface_wind_wave_directional_spread 
sea_surface_wind_wave_energy_at_variance_spectral_density_maximum 
sea_surface_wind_wave_period_at_variance_spectral_density_maximum
b. Storm surge names proposed by Andrew Saulter.
non_tidal_elevation_of_sea_surface_height 
tidal_sea_surface_height_above_lowest_astronomical_tide 
tidal_sea_surface_height_above_mean_sea_level 
c. Platform heave names proposed by Steve Hamilton.
platform_heave 
platform_heave_rate
2. New aliases
No new aliases were added in this update.
3. Modifications to definitions of existing names
a. Platform names
In the discussion of the new platform_heave names it was agreed that the definition of 'platform' should be expanded to read 'Platforms include, but are not limited to, satellites, aeroplanes, ships, instruments and buoys'. This text was added to the definitions of 11 existing names:
angle_of_rotation_from_solar_azimuth_to_platform_azimuth 
platform_azimuth_angle 
platform_course 
platform_id 
platform_name 
platform_speed_wrt_air 
platform_speed_wrt_ground 
platform_speed_wrt_sea_water 
platform_view_angle 
platform_zenith_angle
relative_platform_azimuth_angle
b. Precipitation names
Discussion of the CMIP6 PMIP names led to an explanatory sentence for 'precipitation': ' "Precipitation in the earth's atmosphere means precipitation of water in all phases.' This text was added to the definitions of 29 existing names:
change_over_time_in_amount_of_ice_and_snow_on_land 
change_over_time_in_thermal_energy_content_of_ice_and_snow_on_land 
convective_precipitation_amount 
convective_precipitation_flux 
convective_precipitation_rate 
lwe_convective_precipitation_rate 
lwe_precipitation_rate 
lwe_stratiform_precipitation_rate 
lwe_thickness_of_convective_precipitation_amount 
lwe_thickness_of_precipitation_amount 
lwe_thickness_of_stratiform_precipitation_amount 
mass_fraction_of_precipitation_in_air 
number_of_days_with_lwe_thickness_of_precipitation_amount_above_threshold  
precipitation_amount 
precipitation_flux 
shallow_convective_precipitation_flux 
spell_length_of_days_with_air_temperature_above_threshold 
spell_length_of_days_with_air_temperature_below_threshold 
spell_length_of_days_with_lwe_thickness_of_precipitation_amount_above_threshold 
spell_length_of_days_with_lwe_thickness_of_precipitation_amount_above_threshold 
spell_length_of_days_with_lwe_thickness_of_precipitation_amount_below_threshold 
spell_length_of_days_with_lwe_thickness_of_precipitation_amount_below_threshold 
stratiform_precipitation_amount 
stratiform_precipitation_flux 
tendency_of_air_temperature_due_to_stratiform_cloud_and_precipitation 
tendency_of_air_temperature_due_to_stratiform_cloud_and_precipitation_and_boundary_layer_mixing 
tendency_of_air_temperature_due_to_stratiform_precipitation 
tendency_of_specific_humidity_due_to_stratiform_cloud_and_precipitation 
tendency_of_specific_humidity_due_to_stratiform_precipitation 
c. The name water_evaporation_amount_from_canopy has an alias of water water_evaporation_amount_from_canopy_where_land. Text was added to the definition to explain the deprecation of 'where' names: 'Unless indicated in the cell_methods attribute, a quantity is assumed to apply to the whole area of each horizontal grid box. Previously, the qualifier "where_type" was used to specify that the quantity applies only to the part of the grid box of the named type. Names containing the where_type qualifier are deprecated and newly created data should use the cell_methods attribute to indicate the horizontal area to which the quantity applies.'

V59 standard name changes - 25 September 2018
1. New names
Minus tendency names proposed by Martin Juckes for CMIP6 OMIP.
minus_tendency_of_ocean_mole_content_of_elemental_nitrogen_due_to_denitrification_and_sedimentation 
minus_tendency_of_ocean_mole_content_of_inorganic_carbon_due_to_sedimentation 
minus_tendency_of_ocean_mole_content_of_iron_due_to_sedimentation 
minus_tendency_of_ocean_mole_content_of_organic_carbon_due_to_sedimentation 
2. New aliases
No new aliases were added in this update.
3. Modifications to definitions of existing names
A typographical error in the definition of tendency_of_ocean_mole_content_of_elemental_nitrogen_due_to_denitrification_and_sedimentation was corrected ('gasesous' to 'gaseous').
