Dear Alison, Jonathan,
Thanks for these final suggestions. I agree with these proposals. I have a reservation about the interpretation of "sensible heat flux" which was mentioned in the discussion, but that does not need to delay approval of these proposed terms which neatly avoid the problem. The usage of "sensible heat flux" outside the standard name list consistently refer to it as a thermodynamic property, not something which is specific to a particular medium. In the existing standard names which include the phrase "sensible_heat_flux" the descriptive text suggests that it applies to heat flux through air alone, implicitly excluding any heat flux conveyed by precipitation. It looks to me as though the wording is a reflection of the state of models at the time the standard names were defined, when it may have been reasonable to omit mention of transport of heat by precipitation and equate sensible heat flux at the surface to turbulent heat flux at the surface. As models can now, apparently, resolve the sensible heat flux associated with falling rain, I can't see any reason for maintaining an interpretation of "sensible_heat_flux" in standard names which conflicts with the normal usage. regards, Martin ________________________________ From: CF-metadata <[email protected]> on behalf of Jonathan Gregory <[email protected]> Sent: 01 July 2018 18:27 To: [email protected] Subject: [CF-metadata] Final 17 terms for CMIP6 LS3MIP: Heat flux into snowpack Dear Alison and Martin > tendency_of_thermal_energy_content_of_surface_snow_due_to_rainfall_temperature_excess_above_freezing I think this suggestion of Alison's is very good, to describe the rainfall temperature flux as a change in heat content due to X rather than as the problematic X heat flux. Thanks. > inward_water_volume_transport_along_river_channel > outward_water_volume_transport_along_river_channel > OR > incoming_water_volume_transport_along_river_channel > outgoing_water_volume_transport_along_river_channel. I prefer the latter pair still, but I don't mind.
