Dear Alison > carbon_dioxide_ice_amount; kg m-2 > This is the mass per unit area of frozen carbon dioxide on the Martian > surface.
I propose that "ice" should be reserved for water ice, and that "surface" should be included here, like e.g. surface_snow_amount. Thus: surface_frozen_carbon_dioxide_amount With regard to John's question, I think there is no problem for using the same standard names for Earth and Mars quantities if they refer to the same physical quantities, just like we can use the same standard names for different future scenarios for the Earth, or past geological periods. The Earth in the Cambrian was not the same planet as the Earth today regarding all its climate and geophysical circumstances (although not as different as Mars). The fact that it is Mars is presumably made clear in some other metadata, which could be standardised if necessary. The Earth as simulated by various climate models is also not the same Earth as the one we live on - sometimes quite bizarrely different - and these models are distinguished informally by global attributes.
