Re: [CF-metadata] Standard names for LS3MIP: 8 temporal changes + 1 feature depth

2018-05-18 Thread Jonathan Gregory
Dear Martin I agree that the quantity doesn't exist everywhere, but that's the same if you give it a name of its own rather than the more general name of depth. I suggest that specifying the coordinate as soil_temperature specifically implies that it must be non-existent where 0degC is above groun

Re: [CF-metadata] No standard names for element concentrations in sediment?

Hi (yet) again, Overnight I remembered a debate on CF about not using'dissolved inorganic silicon' rather than 'silicate' in new Standard Names. I also think it's worth some clarification in the definition to explain how things can be dissolved in something that many would think of as a solid.

Dear Jonathan, I agree that the 0C isotherm does not exist everywhere, but it is still a different variable to the one requested. You could try to persuade LS3MIP to use the variable you are describing, but I'm not yet convinced that we can't provide a means of describing the variable they wan

Hi, Thanks for correction. I realized that I need a standard name not only for silicate but for biogenic silica plus silicate. I updated the proposed name and description as follows: moles_of_silicon_per_unit_area_in_seabed_sediment unit: mol/m2 description: moles_of_X_per_unit_area_in_Y de

Hi Daniel, Most of the solids in sediment are silicate minerals, quite often quartz (silicon dioxide), which would be included in 'moles_of_silicon' So, I suggest: moles_of_dissolved_inorganic_plus_biogenic_silicon_per_unit_area_in_seabed_sediment unit: mol/m2 description: moles_of_X_per_un

Dear Daniel and Roy I sent an email yesterday which for some reason disappeared into the void. Please could I request sea_floor_sediment instead of seabed_sediment? That's because we already use sea_floor in several standard names, but not sedbed. Best wishes Jonathan - Forwarded message fr

Dear Martin Ah, I see. Sorry, I hadn't grasped that point. I certainly don't want to try to persuade LS3MIP to provide something to suit CF. CF should try to describe what people want to use. I think your suggestion below is a good one. We could use the standard_name of depth with a coordinate va

Dear Jonathan, That sounds reasonable, but does it deal with the possibility that there is more than one 0 degC isotherm? If the ground is unfrozen and there is one or more 0 degC isotherms below ground, we want the depth to the first one. Would "cell_methods = depth: minimum" deal with this?

Dear Jonathan, I believe that they are repeat calculations in the model, as you suggest. They have been requested for PMIP by Yves Balkanski, so Yves may be able to comment more on this point (the question refers to swsrfasdust and related variables), regards, Martin __
