2. Aliases

a. Sixteen aliases were created to change 'seasalt' to 'sea_salt'. Thank you to Daniel Neumann for pointing out inconsistencies in existing names.

This change ensures consistency across all sea_salt standard names. The definitions of the terms are unaffected.

tendency_of_atmosphere_mass_content_of_seasalt_dry_aerosol_particles_due_to_wet_deposition -> tendency_of_atmosphere_mass_content_of_sea_salt_dry_aerosol_particles_due_to_wet_deposition

tendency_of_atmosphere_mass_content_of_seasalt_dry_aerosol_particles_due_to_gravitational_settling -> tendency_of_atmosphere_mass_content_of_sea_salt_dry_aerosol_particles_due_to_gravitational_settling

tendency_of_atmosphere_mass_content_of_pm2p5_seasalt_dry_aerosol_particles_due_to_emission -> tendency_of_atmosphere_mass_content_of_pm2p5_sea_salt_dry_aerosol_particles_due_to_emission

tendency_of_atmosphere_mass_content_of_pm2p5_seasalt_dry_aerosol_particles_due_to_dry_deposition -> tendency_of_atmosphere_mass_content_of_pm2p5_sea_salt_dry_aerosol_particles_due_to_dry_deposition

tendency_of_atmosphere_mass_content_of_pm10_seasalt_dry_aerosol_particles_due_to_dry_deposition -> tendency_of_atmosphere_mass_content_of_pm10_sea_salt_dry_aerosol_particles_due_to_dry_deposition

mass_fraction_of_seasalt_dry_aerosol_particles_in_air -> mass_fraction_of_sea_salt_dry_aerosol_particles_in_air
mass_concentration_of_seasalt_dry_aerosol_particles_in_air -> mass_concentration_of_sea_salt_dry_aerosol_particles_in_air
atmosphere_optical_thickness_due_to_seasalt_ambient_aerosol_particles -> atmosphere_optical_thickness_due_to_sea_salt_ambient_aerosol_particles
atmosphere_mass_content_of_seasalt_dry_aerosol_particles -> atmosphere_mass_content_of_sea_salt_dry_aerosol_particles
atmosphere_absorption_optical_thickness_due_to_seasalt_ambient_aerosol_particles -> atmosphere_absorption_optical_thickness_due_to_sea_salt_ambient_aerosol_particles

tendency_of_atmosphere_mass_content_of_seasalt_dry_aerosol_particles_due_to_dry_deposition -> tendency_of_atmosphere_mass_content_of_sea_salt_dry_aerosol_particles_due_to_dry_deposition

tendency_of_atmosphere_mass_content_of_pm2p5_seasalt_dry_aerosol_particles_due_to_wet_deposition -> tendency_of_atmosphere_mass_content_of_pm2p5_sea_salt_dry_aerosol_particles_due_to_wet_deposition

tendency_of_atmosphere_mass_content_of_pm10_seasalt_dry_aerosol_particles_due_to_wet_deposition -> tendency_of_atmosphere_mass_content_of_pm10_sea_salt_dry_aerosol_particles_due_to_wet_deposition

tendency_of_atmosphere_mass_content_of_pm10_seasalt_dry_aerosol_particles_due_to_emission -> tendency_of_atmosphere_mass_content_of_pm10_sea_salt_dry_aerosol_particles_due_to_emission

tendency_of_atmosphere_mass_content_of_seasalt_dry_aerosol_particles_due_to_turbulent_deposition -> tendency_of_atmosphere_mass_content_of_sea_salt_dry_aerosol_particles_due_to_turbulent_deposition

tendency_of_atmosphere_mass_content_of_seasalt_dry_aerosol_particles_due_to_emission -> tendency_of_atmosphere_mass_content_of_sea_salt_dry_aerosol_particles_due_to_emission

b. Three aliases were added to clarify recently created nitrogen deposition names (originally proposed by Daniel Neumann).

These names were changed to clarify that they refer to the mass of only the nitrogen contained in the compounds.

tendency_of_atmosphere_mass_content_of_nitrogen_due_to_deposition -> tendency_of_atmosphere_mass_content_of_nitrogen_compounds_expressed_as_nitrogen_due_to_deposition
     
tendency_of_atmosphere_mass_content_of_nitrogen_due_to_dry_deposition -> tendency_of_atmosphere_mass_content_of_nitrogen_compounds_expressed_as_nitrogen_due_to_dry_deposition

tendency_of_atmosphere_mass_content_of_nitrogen_due_to_wet_deposition -> tendency_of_atmosphere_mass_content_of_nitrogen_compounds_expressed_as_nitrogen_due_to_wet_deposition

c. Eight aliases were created to change 'sea_level' to 'mean_sea_level'.

This change was made to help clarify the difference between (instantaneous) sea surface height and mean sea level. In addition to creating the aliases the definitions were updated by removing the sentence 'sea_level means mean sea level, which is close to the geoid in sea areas' and replacing it with ' "Mean sea level" means the time mean of sea surface elevation at a given location over an arbitrary period sufficient to eliminate the tidal signals.' Thanks to Jonathan Gregory and Roy Lowry for working on these changes.

air_pressure_at_sea_level -> air_pressure_at_mean_sea_level                           
sea_surface_height_above_sea_level -> sea_surface_height_above_mean_sea_level
sea_floor_depth_below_sea_level -> sea_floor_depth_below_mean_sea_level
tendency_of_sea_surface_height_above_sea_level -> tendency_of_sea_surface_height_above_mean_sea_level    
surface_geostrophic_eastward_sea_water_velocity_assuming_sea_level_for_geoid -> surface_geostrophic_eastward_sea_water_velocity_assuming_mean_sea_level_for_geoid            
surface_geostrophic_northward_sea_water_velocity_assuming_sea_level_for_geoid -> surface_geostrophic_northward_sea_water_velocity_assuming_mean_sea_level_for_geoid
surface_geostrophic_sea_water_x_velocity_assuming_sea_level_for_geoid -> surface_geostrophic_sea_water_x_velocity_assuming_mean_sea_level_for_geoid     
surface_geostrophic_sea_water_y_velocity_assuming_sea_level_for_geoid -> surface_geostrophic_sea_water_y_velocity_assuming_mean_sea_level_for_geoid

3. Modifications to definitions of existing names

a. Updates to _pm*_ definitions proposed by Daniel Neumann.

Daniel pointed out that all definitions of _pm*_ names described the aerosol particles as "atmospheric pollutants" but this is not correct in all cases, for example, sea salt is a naturally occurring aerosol. The definitions were updated to remove the reference to pollutants, e.g., the sentence ' "Pm1 aerosol" is an air pollutant with an aerodynamic diameter of less than or equal to 1 micrometer' was replaced with ' "Pm1 aerosol" means atmospheric particulate compounds with an aerodynamic diameter of less than or equal to 1 micrometer.' This change affects the 52 existing names listed below.

atmosphere_optical_thickness_due_to_pm1_ambient_aerosol_particles

b. Cross-references to mean_sea_level names
