Abstract: Recent developments in studies of carbon dioxide (CO2) exchanges between terrestrial ecosystems and the atmosphere point to a relevant role by caves and other belowground airspaces. In such speleological environments, partial pressures of CO2 are often large enough to affect overall air density. Excluding this gas when defining the gas constant for air, a new definition is proposed for the virtual temperature Ty that remains valid for the atmosphere in general but furthermore serves to examine the buoyancy of CO2-rich air in caves and other subterranean airspaces. Taking this definition into account, the increase in CO2 with depth in the soil profile, generally observed around the world, can be explained by simple gravitational settling.
