TLDR
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.Abstract:
The individual absorption coefficient curves of NO2 and N2O4, separated by means of a mechanical analog differential analyzer are presented. Beer's law is assumed to be applicable to the system. The range 2400–5000A is covered. A discussion of the apparently continuous nature of the N2O4 absorption is included.read more

Visibility: Science and Regulation
TL;DR: Simpler models representing transport, limiting precursor pollutants, and gas-to-particle equilibrium should be used to understand where and when emission reductions will be effective, rather than large complex models that have insufficient input and validation measurements.

Reduction of stratospheric ozone by nitrogen oxide catalysts from supersonic transport exhaust.
TL;DR: 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.

Solar photo rates for planetary atmospheres and atmospheric pollutants
TL;DR: In this article, the rate coefficients and excess energies for dissociation, ionization, and dissociative ionization are presented for atomic and molecular species that have been identified or are suspected to exist in the atmospheres of planets, satellites (moons), comets, or as pollutants in the Earth atmosphere.

Ozone production rates in an oxygen-hydrogen-nitrogen oxide atmosphere
TL;DR: In this article, it was shown that an artificial increase of the mixing ratio of the oxides of nitrogen in the stratosphere by about 1×10−8 may lead to observable changes in the atmospheric ozone level.

Triatomic Photofragment Spectra: I. Energy Partitioning in NO2 Photodissociation,
George E. Busch,Kent R. Wilson +1 more
TL;DR: In this paper, the photofragment spectrum of NO2 has been measured in the near ultraviolet at 28 810 cm−1 and at least two prominent peaks in the translational energy distribution were found to correspond to nearly equal probability of recoil with the NO fragment in the v=0 and v=1 vibrational states.
