Dear All,
The standard name table has been updated today as planned. The current
version is now version 15, dated 26 July 2010.
While every effort has been made to ensure that the names, units and
definitions are correct, please let me know if you do spot any mistakes
or omissions.
Best wishes,
Alison

> 1. New aliases for existing names
>
> a. Surface carbon dioxide flux name. Proposed by Jonathan Gregory.
>
> The existing name surface_carbon_dioxide_mole_flux is ambiguous as it
> does not specify the direction of the flux. Two new names will be
> created:
> surface_upward_mole_flux_of_carbon_dioxide; mol m-2 s-1
> surface_downward_mole_flux_of_carbon_dioxide; mol m-2 s-1
> and the existing name will be made an alias of both. This is to avoid
> imposing a (possibly) incorrect sign convention on existing data. The
> definitions of the new names will note that older data written with
the
> alias need to be examined in order to determine which sign convention
> was used.
>
> b. Move 'expressed_as' phrase in aerosol names. Proposed by Jonathan
> Gregory.
>
> This is intended to make the names easier to understand by using a
more
> natural order of wording. It affects five names.

> 2. Clarifications to the definitions of existing names
>
> a. Sinking mole flux names
>
> Jonathan queried the difference between 'sinking' and 'downwelling'
> fluxes. John Dunne explained that 'sinking' is calculated relative to
> a
> moving fluid, whereas 'downwelling' would describe the movement of the
> fluid itself. A sentence will be added to the definition of all the
> sinking mole flux names as follows: "A sinking flux is positive
> downwards and is calculated relative to the movement of the
surrounding
> fluid." This affects seven recently introduced standard names:
> sinking_mole_flux_of_aragonite_expressed_as_carbon_in_sea_water
> sinking_mole_flux_of_calcite_expressed_as_carbon_in_sea_water
> sinking_mole_flux_of_particulate_iron_in_sea_water
