Reduction of stratospheric ozone by nitrogen oxide catalysts from supersonic transport exhaust.
TLDR
The projected increase in stratospheric oxides of nitrogen could reduce the ozone shield by about a factor of 2, thus permitting the harsh radiation below 300 nanometers to permeate the lower atmosphere.Abstract:
Although a great deal of attention has been given to the role of water vapor from supersonic transport (SST) exhaust in the stratosphere, oxides of nitrogen from SST exhaust pose a much greater threat to the ozone shield than does an increase in water. The projected increase in stratospheric oxides of nitrogen could reduce the ozone shield by about a factor of 2, thus permitting the harsh radiation below 300 nanometers to permeate the lower atmosphere.read more

Stratospheric sink for chlorofluoromethanes: chlorine atomc-atalysed destruction of ozone
Mario J. Molina,F. S. Rowland +1 more
TL;DR: Chlorofluoromethanes are being added to the environment in steadily increasing amounts as discussed by the authors and these compounds are chemically inert and may remain in the atmosphere for 40 to 150 years, and concentrations can be expected to reach 10 to 30 times present levels.

Nitrous Oxide (N2O): The Dominant Ozone-Depleting Substance Emitted in the 21st Century
TL;DR: In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.

Nitrous oxide (N_2O) : the dominanat ozone-depleting substance emitted in the 21st century
TL;DR: Nitrous oxide emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century, and N2O is unregulated by the Montreal Protocol, which would enhance the recovery of the ozone layer from its depleted state and reduce the anthropogenic forcing of the climate system.

Stratospheric ozone depletion: A review of concepts and history
TL;DR: A brief history of the science of ozone depletion and a conceptual framework to explain the key processes involved, with a focus on chemistry is described in this article, and observations of ozone and of chlorine-related trace gases near 40 km provide evidence that gas phase chemistry has indeed currently depleted about 10% of the stratospheric ozone there as predicted, and the vertical and horizontal struc- tures of this depletion are fingerprints for that process.

Separation of the Absorption Spectra of NO2 and N2O4 in the Range of 2400–5000A
T. C. Hall,F. E. Blacet +1 more
TL;DR: In this paper, the individual absorption coefficient curves of NO2 and N2O4, separated by means of a mechanical analog differential analyzer, are presented and a discussion of the apparently continuous nature of the N 2O4 absorption is included.

Ultraviolet absorption coefficients of CO2, CO, O2, H2O, N2O, NH3, NO, SO2, and CH4 between 1850 and 4000 A
TL;DR: The ultraviolet absorption coefficients for CO2, CO, O2, H2O, N 2O, NH3, NO, SO2, and CH4 in the wavelength region between 1850 and 4000 A were determined by using a double-beam instrument and a 10-cm path length.
