Stratospheric ozone depletion through catalytic chemistry involving man‐made
chlorofluorocarbons is an area of focus in the study of geophysics and one of the global …

Recent observations by Farman et al. 1 reveal remarkable depletions in the total
atmospheric ozone content in Antarctica. The observed total ozone decreased smoothly …

Large depletions in stratospheric ozone were first reported by Farman et al. 1 at Halley Bay
(76° S), and confirmed by satellite observations2. Chubachi3 gives a detailed account of …

It is now well established that heterogeneous reactions provide an important mechanism for
Antarctic ozone depletion. Recent laboratory studies suggest that the same reactions that …

The reaction probability, γ, of N2O5 (to form HNO3) with monodisperse NH3/H2SO4/H2O
aerosols has been measured in a flow tube reactor at atmospheric pressure. Experiments …

A new two‐dimensional model with detailed photochemistry is presented. The model
includes descriptions of planetary wave and gravity wave propagation and dissipation to …

THERE is a serious discrepancy between estimates of the downward trend in the column
abundance of ozone at middle and high latitudes derived from ground-based and satellite …

The heterogeneous physical and chemical processes that occur in the presence of and
involve polar stratospheric clouds (PSCs) are investigated. The theory developed here is …

A perspective is given on the emissions of aircraft in the stratosphere, on the occasion of the
50th anniversary of the article that initiated concerns about the ability of nitrogen oxides from …

We have measured the rate of reaction of N2O5 with H2O on monodisperse, submicrometer
H2SO4 particles in a low‐temperature flow reactor. Measurements were carried out at …
