... for air. The small negative MIF signature in bulk tropospheric O 2 with D 17 O ~ −0.2‰, results from the storage of a positive MIF signature in stratospheric CO 2 via transfer from O 3 by the excited state atom O( 1 D) ( Yung et al. 1991 ). This powerful technique has also been applied to O 2...

A numerical model was developed to understand the mechanism controlling gas flow, which was found to be the relative buoyancy of the gas phase within the dump compared with atmospheric air. Changes in atmospheric air density are caused by atmospheric temperature variations, whereas dump gas-phase...
