Dear Roy, Jonathan and Veronika,
Thanks to Roy and Jonathan for pointing out that there are
inconsistencies between some of the new CCMVal names and existing
velocity and momentum flux names. I must admit that I hadn't really
noticed that all the existing velocity names also specify "air",
"atmosphere", "sea_water", etc.
Veronika has suggested a list of aliases for the CCMVal names as
follows:
eastward_transformed_eulerian_mean_velocity ->
eastward_transformed_eulerian_mean_air_velocity
northward_transformed_eulerian_mean_velocity ->
northward_transformed_eulerian_mean_air_velocity
northward_eliassen_palm_flux -> northward_eliassen_palm_flux_in_air
upward_eliassen_palm_flux -> upward_eliassen_palm_flux_in_air
northward_heat_flux_due_to_eddy_advection ->
northward_heat_flux_in_air_due_to_eddy_advection
upward_flux_of_eastward_momentum_due_to_nonorographic_eastward_gravity_w
aves ->
upward_eastward_momentum_flux_in_air_due_to_nonorographic_eastward_gravi
ty_waves
upward_flux_of_eastward_momentum_due_to_nonorographic_westward_gravity_w
aves ->
upward_eastward_momentum_flux_in_air_due_to_nonorographic_westward_gravi
ty_waves
upward_flux_of_eastward_momentum_due_to_orographic_gravity_waves ->
upward_eastward_momentum_flux_in_air_due_to_orographic_gravity_waves
An additional sentence will be needed in the definitions of the gravity
wave names to explain the meaning of "upward_eastward".
These suggestions are all in line with existing names and I plan to
introduce them into the standard name table at the next update on 13th
May.
Best wishes,
Alison
