A new definition of the virtual temperature, valid for the atmosphere and the CO2-rich air of the vadose zone Kowalski, Andrew Pérez Sánchez-Cañete, Enrique Temperature Carbon dioxide In speleological environments, partial pressures of carbon dioxide (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 Tυ 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. 2012-11-16T13:08:59Z 2012-11-16T13:08:59Z 2010-08 journal article Kowalski, Andrew S.; Sánchez-Cañete, E.P.
