Dear Karl, I can see your concern, and clearly we do have to draw a line somewhere. We currently have 856 terms using the "due_to" construction. The temperature change variables you refer to can only be calculated by multiple runs of a full climate model, and I agree that it is not appropriate

Hi again, I think all you need for the second Standard Name is: moles_of_silicate_per_unit_area_in_seabed_sediment as there is one atom of silicon per molecule of any of the species making up 'silicate'. You only really need 'expressed_as_silicon' for 'mass_of_silicate'. Cheers, Roy. I a

Great :-) . Then I would like to propose the following two new standard names: moles_of_nitrogen_per_unit_area_in_seabed_sediment unit: mol/m2 description: moles_of_X_per_unit_area_in_Y describes the amount of X in a column with unity base area of material/compartment Y. 'Sediment' means

Dear Jonathan, Yes, it should be 0C, not 0K. I don't think the approach you suggest will work because what we need is the depth of the first 0C isotherm assuming surface temperature above 0C. We don't want the depth of the 0C isotherm in regions where the surface temperature is < 0C. I can't

Dear Alison, Martin, and all On the last point commented on by Martin: "4.3-4.7 Perturbed radiation calculations" I wonder if it is wise to assign a new name every time experiment conditions change.  I would limit names to quantities that are calculated independently by a physics model or tha

Dear Jonathan, Of the options you suggest, I think "minus_tendency_" is the neatest, being more compact that "minus_one_times_tendency_" without, as far as I can see, introducing any ambiguity. I had a look on-line for antonyms of tendency, and discovered that our usage of "tendency" as an a

Dear Roy, Dear Jonathan, Thank you for the feedback. I see  that sediment might be ambiguous. Would "seabed sediment" or "marine seabed sediment" be an acceptable alternative?   moles_of_nitrogen_per_unit_area_in_seabed_sediment This would clarify that the sea floor is meant as location of t

Dear Jonathan, Whilst that is one meaning of the word 'sediment', it is not the only one. The word is also used to describe the material collected by coring the seabed or filtering muddy waters which is then analysed for many chemical and biological substances. We have a lot of this kind of da
