New items for discussion

Standard names

• Should units control what kind of mixing ratio (volume, mass, number concentration) it is as opposed to the standard name?
• How should moist/dry/wet mixing ratio property be set? How can we make sure this works properly with variable standard names? Currently this property is set based off the standard name itself, although the actual names being used are out-of-date: https://github.com/peverwhee/ccpp-framework/blob/add_const_interface/src/ccpp_constituent_prop_mod.F90#L421
• Should moist/dry/wet be controlled by standard name, or by metadata property [like "advected"] (which the constituents property object is carrying around anyways)? Also should there not be a default value (to make sure the property is always set)?
• What units do we want to support for unit conversion?
