Dear Jonathan G,

I follow your logic and what you say makes sense - "ambient air" is implied as the parcel destination by the product standard name. But, to me, it seems that "ambient air pressure" is too general for application to the lifted-type stability products, especially since two coordinate variables are sometimes needed. In effect, the original air pressure is an ambient air pressure, too, so there is not enough differentiation. Plus, for consistency, the use of 'original' and 'final' is nice. I think we had a vote this way from Seth, too.

Just my thoughts - I can go either way, ultimately.

Thanks for your patience! I am pretty happy with this, but I will just have
a last go with "ambient", to see what you think. My logic is that

temperature_difference_between_ambient_air_and_air_lifted_adiabatically_from_the_surface
temperature_difference_between_ambient_air_and_air_lifted_adiabatically
implicitly seem to regard "ambient air" as the destination. Hence it could
make sense to use

original_air_pressure_of_lifted_parcel
ambient_air_pressure, or even just air_pressure (an existing stdname)
as the coordinates. It sounds a bit more physical than "finish".

Best wishes

Jonathan
