Dear Dave

Thanks for the text listing of your proposals. Here are a few comments:

These ones are existing standard names:
  surface_net_downward_mass_flux_of_carbon_dioxide_expressed_as_carbon_due_to_all_land_processes
  moisture_content_of_soil_layer
  soil_moisture_content

I see that there is already a standard name of surface_downward_water_flux.
For consistency, I think the existing standard name should be changed (by
alias) to surface_downward_mass_flux_of_water for consistency with your
proposal
  surface_downward_mass_flux_of_water_due_to_crop_irrigation
or yours should be changed to
  surface_downward_water_flux_due_to_crop_irrigation

* surface_upward_sensible_heat_flux_due_to_anthropogenic_energy_consumption
In the definition you call this "anthropogenic heat flux". That sounds more
general. Is it really an upward sensible heat flux specifically - no latent
heat flux, for instance? Or do you mean the heat released per unit area and
per unit time by anthropogenic energy use, no matter what happens to it?

* tendency_of_atmosphere_mass_content_of_carbon_due_to_emission_from_anthropogenic_product_pool
Is this really carbon and not carbon_dioxide_expressed_as_carbon, like
others? What is the difference between this and the existing standard name
  tendency_of_atmosphere_mass_content_of_carbon_dioxide_expressed_as_carbon_due_to_anthropogenic_emission
Actually I don't know what "anthropogenic product pool" means. It isn't a
phrase known to Google. Is there an alternative? Consequently I also don't
understand this one
  carbon_mass_flux_into_anthropogenic_product_pools_due_to_land_use_land_cover_change

* carbon_mass_flux_into_soil_or_litter_pools_due_to_land_use_land_cover_change
I guess this should be ..._due_to_land_use_or_land_cover_change

* carbon_mass_flux_direct_to_atmosphere_due_to_land_use_land_cover_change
By analogy with several existing names of the form
  surface_upward_mass_flux_of_carbon_dioxide_expressed_as_carbon_due_to_X
could this one be
  surface_upward_mass_flux_of_carbon_dioxide_expressed_as_carbon_due_to_land_use_or_land_cover_change

* change_over_time_in_area_fraction
It is OK for this to be change_over_time but would it be better as a rate i.e.
  tendency_of_area_fraction
for which the canonical unit would be s-1? It could still be expressed as
yr-1 so numerically the same.

Best wishes

Jonathan
