error in canonical units of atmosphere_convective* quantities
Units: J kg-1 (JPKG)
Updated term description
Convective(ly) available potential energy (often abbreviated CAPE) is a stability measure calculated by integrating the positive temperature difference between the surrounding atmosphere and a parcel of air lifted adiabatically from the surface to its equilibrium level. CAPE exists under conditions of potential instability, and measures the potential energy per unit mass that would be released by the unstable parcel if it were able to convect upwards to equilibrium.

error in canonical units of atmosphere_convective* quantities
Units: J kg-1 (JPKG)
Updated term description
Convective inhibition is the amount of energy per unit mass required to overcome the negatively buoyant energy exerted by the environment on a parcel of air. Convective inhibition is often abbreviated as "CIN" or "CINH". It is calculated by integrating the negative temperature difference between the surrounding atmosphere and a parcel of air lifted adiabatically from the surface to its equilibrium level.

Updated term description
Convective inhibition is the amount of energy per unit mass required to overcome the negatively buoyant energy exerted by the environment on a parcel of air. Convective inhibition is often abbreviated as "CIN" or "CINH". It is calculated by integrating the negative temperature difference between the surrounding atmosphere and a parcel of air lifted adiabatically from a given starting height to its equilibrium level. A coordinate variable of original_air_pressure_of_lifted_parcel should be specified to indicate the starting height of the lifted parcel.

Insert of_radiative_flux in four volume...coefficient names
Units: m-1 (UPRM)
Term change from Term: volume_absorption_coefficient_in_air_due_to_dried_aerosol_particles
The volume scattering/absorption/attenuation coefficient is the fractional change of radiative flux per unit path length due to the stated process. Coefficients with canonical units of m2 s-1 i.e. multiplied by density have standard names with "specific_" instead of "volume_". The scattering/absorption/attenuation coefficient is assumed to be an integral over all wavelengths unless a coordinate of "radiation_wavelength" or "radiation_frequency" is included to specify the wavelength. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. "Dried_aerosol" means that the aerosol sample has been dried from the ambient state, but that the dry state (relative humidity less than 40 per cent) has not necessarily been reached. To specify the relative humidity at which the sample was measured, provide a scalar coordinate variable with the standard name of "relative_humidity". The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase.

Standard names: particulate carbon terms
Units: kg m-3 (UKMC)
New Term
Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol takes up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the aerosol. "Dry aerosol particles" means aerosol particles without any water uptake. "Pm1 aerosol" means atmospheric particulate compounds with an aerodynamic diameter of less than or equal to 1 micrometer. Chemically, "elemental carbon" is the carbonaceous fraction of particulate matter that is thermally stable in an inert atmosphere to high temperatures near 4000K and can only be gasified by oxidation starting at temperatures above 340 C. It is assumed to be inert and non-volatile under atmospheric conditions and insoluble in any solvent (Ogren and Charlson, 1983). Elemental carbon may include inorganic carbon, which is operationally distributed between elemental and organic carbon.

Dinoflagellates (dinophytes) are mostly unicellular, rarely colonial, biflagellated algae with cell walls firm, or reinforced with polygonal plates. They produce some of the most potent toxins known.

Standard names: tidal_sea_surface_height_above_reference_datum and sea_level_residual
Units: m (ULAA)
New Term
"Sea surface height" is a time-varying quantity. "Height_above_X" means the vertical distance above the named surface X, in this case above an arbitrary reference datum. The altitude of the datum should be provided in a variable with standard name tidal_sea_surface_height_above_reference_datum. The tidal component of sea surface height describes the predicted variability of the sea surface due to astronomic forcing (chiefly lunar and solar cycles) and shallow water resonance of tidal components; for example as generated based on harmonic analysis, or resulting from the application of harmonic tidal series as boundary conditions to a numerical tidal model.

The volume scattering/absorption/attenuation coefficient is the fractional change of radiative flux per unit path length due to the stated process. Coefficients with canonical units of m2 s-1 i.e. multiplied by density have standard names with specific_ instead of volume_. A scattering_angle should not be specified with this quantity. The scattering/absorption/attenuation coefficient is assumed to be an integral over all wavelengths, unless a coordinate of radiation_wavelength is included to specify the wavelength. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. "Dried_aerosol_particles" means that the aerosol sample has been dried from the ambient state before sizing, but that the dry state (relative humidity less than 40 per cent) has not necessarily been reached. To specify the relative humidity at which the sample was measured, provide a scalar coordinate variable with the standard name of "relative_humidity". The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Pm1 aerosol particles" means atmospheric particulate compounds with an aerodynamic diameter of less than or equal to 2.5 micrometers. "Standard_temperature_and_pressure" refer to a reference volume at 273.15 K temperature and 1013.25 hPa pressure.

Updated term description
Water means water in all phases. Evaporation is the conversion of liquid or solid into vapor. (The conversion of solid alone into vapor is called "sublimation".) The process of transpiration is not included. In accordance with common usage in geophysical disciplines, "flux" implies per unit area, called "flux density" in physics. 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. In the versions before 56 transpiration was not mentioned and for versions 56 to 71 it was allowed to use water_evaporation_flux as an alias.

New Term
Water means water in all phases. "Evapotranspiration" means all water vapor fluxes into the atmosphere from the surface: liquid evaporation, sublimation, and transpiration. Evaporation is the conversion of liquid or solid into vapor. Transpiration is the process by which water is carried from the roots of plants and evaporates from the stomata. (The conversion of solid alone into vapor is called "sublimation".) "Amount" means mass per unit area. Unless indicated in the cell_methods attribute, a quantity is assumed to apply to the whole area of each horizontal grid box.

Also commonly known as Chromophoric Dissolved Organic Matter (CDOM). CDOM plays an important role in the carbon cycling and biogeochemistry of coastal waters. It occurs naturally in aquatic environments primarily as a result of matter released from decaying plant and animal matter, which can enter coastal areas in river run-off containing organic materials leached from soils. Fluorescence intensity is normalised to the integrated Raman scattering peak of pure water from excitation at 350 nm, and therefore reported in Raman Units. The wavelengths that fluorescence is measured at will depend on the sensor used and is stated as an radiation_wavelength attribute (eg. “Ex350nm Em460nm”).

A positive value means that the soil becomes falsely wetter in a model and a negative value means the soil becomes falsely dryer. It should be noted, that the residuum has to be calculated excluding climatological layers where the temperature or the soil water content is kept to a climatological value or a value given by another soil layer.

A period is an interval of time, or the time-period of an oscillation. The sea_surface_wave_period_at_variance_spectral_density_maximum, sometimes called peak wave period, is the period of the most energetic waves in the total wave spectrum at a specific location. Wave period is the interval of time between repeated features on the waveform such as crests, troughs or upward passes through the mean level. The wave directional spectrum can be written as a five dimensional function S(t,x,y,f,theta) where t is time, x and y are horizontal coordinates (such as longitude and latitude), f is frequency and theta is direction. S has the standard name sea_surface_wave_directional_variance_spectral_density. S can be integrated over direction to give S1= integral(S dtheta) and this quantity has the standard name sea_surface_wave_variance_spectral_density. The density of a substance is its mass per unit volume. The phrase "wave_period_at_variance_spectral_density_maximum", sometimes called peak wave period, describes the period of the most energetic waves within a given sub-domain of the wave spectrum.

The quantity with standard name ratio_of_sea_water_practical_salinity_anomaly_to_relaxation_timescale is a correction term applied to modelled sea water practical salinity. The term is estimated as the deviation of model local sea water practical salinity from an observation-based climatology (e.g. World Ocean Database) weighted by a user-specified relaxation coefficient in s-1 (1/(relaxation timescale)). The phrase "ratio_of_X_to_Y" means X/Y. The term "anomaly" means difference from climatology. Practical Salinity, S_P, is a determination of the salinity of sea water, based on its electrical conductance. The measured conductance, corrected for temperature and pressure, is compared to the conductance of a standard potassium chloride solution, producing a value on the Practical Salinity Scale of 1978 (PSS-78). This name should not be used to describe salinity observations made before 1978, or ones not based on conductance measurements. Conversion of Practical Salinity to other precisely defined salinity measures should use the appropriate formulas specified by TEOS-10. Other standard names for precisely defined salinity quantities are sea_water_absolute_salinity (S_A); sea_water_preformed_salinity (S_*), sea_water_reference_salinity (S_R); sea_water_cox_salinity (S_C), used for salinity observations between 1967 and 1977; and sea_water_knudsen_salinity (S_K), used for salinity observations between 1901 and 1966. Salinity quantities that do not match any of the precise definitions should be given the more general standard name of sea_water_salinity. Reference: www.teos-10.org; Lewis, 1980 doi:10.1109/JOE.1980.1145448. To specify the reference (baseline) epoch to which the quantity applies, provide a scalar coordinate variable with standard name reference_epoch.

New standard names for atmospheric sea salt and for nitrogen deposition
Units: 1 (UUUU)
New Term
Mass fraction is used in the construction "mass_fraction_of_X_in_Y", where X is a material constituent of Y. It means the ratio of the mass of X to the mass of Y (including X). A chemical or biological species denoted by X may be described by a single term such as "nitrogen" or a phrase such as "nox_expressed_as_nitrogen". "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. Aerosol particles take up ambient water (a process known as hygroscopic growth) depending on the relative humidity and the composition of the particles. "Dry aerosol particles" means aerosol particles without any water uptake. The chemical formula for chloride is Cl-.

standard_names for wind stress curl, wind stress divergence
Units: N m-3 (NCUM)
New Term
The surface downward stress is the wind stress on the surface. The quantity with standard name vertical_component_of_curl_of_surface_downward_stress is a signed scalar that represents the magnitude of the 2D surface wind downward stress vector field's local anti-clock-wise rotation at a given point; clockwise rotation is thus given as negative curl. The surface called "surface" means the lower boundary of the atmosphere. "Downward" indicates a downward flux of momentum, which accelerates the lower medium along the vector and the upper medium against the vector.

New Term
The surface downward stress is the wind stress on the surface. The quantity with standard name divergence_of_surface_downward_stress is a signed scalar that represents the magnitude of the 2D surface wind downward stress vector field's source (positive) or sink (negative) at a given point. The surface called "surface" means the lower boundary of the atmosphere.
