Photochemistry of minor constituents in the troposphere
TLDR
In this article, the altitude profiles for the number densities of H2O, CH4, H2, CO, O3, and the sum of NO and NO2 are calculated as a function of time of day with a steady-state photochemical model.About:

Biogeochemical aspects of atmospheric methane
TL;DR: In this paper, the authors identify and evaluate several constraints on the budget of atmospheric methane, its sources, sinks and residence time, and construct a list of sources and sinks, identities, and sizes.
Journal ArticleDOI
Chlorofluoromethanes in the Environment
F. S. Rowland,Mario J. Molina +1 more
TL;DR: In this article, the photoprocesses of atmospheric chlorofluoromethanes, including their ultimate sinks, are studied. Butt et al. present a detailed study of the photodissociation process of chlorofluromethane.

A discussion of the chemistry of some minor constituents in the stratosphere and troposphere
TL;DR: In this article, a discussion is given of atmospheric reactions in the H2O−CH4−O2−O3−NO ≥ 3−NO fixme x system.

Photochemical reactions initiated by and influencing ozone in unpolluted tropospheric air
TL;DR: In this paper, the photochemical effect of both scattered and direct radiation at ground levels and adopting recent accurate data for the quantum efficiency of O( 1 D) production in the ozone photolysis near 310 nm.
Journal ArticleDOI
A photochemical theory of tropospheric ozone
TL;DR: In this article, a photochemical theory for tropospheric ozone was presented, in which the methane oxidation chain constitutes a large local source, and this source produces about one trillion odd oxygen molecules per square centimeter per second.

Normal atmosphere: large radical and formaldehyde concentrations predicted.
TL;DR: A radical chain reaction is proposed for the rapid removal of carbon monoxide, leading to acarbon monoxide lifetime as low as 0.2 year in the surface 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.

Hydroxyl Radical Kinetics by Kinetic Spectroscopy. VI. Reactions with Alkanes in the Range 300–500°K
TL;DR: In this paper, the reactivity of OH radicals toward a representative set of alkanes was studied and the following formula was found to reproduce accurately all of the observed abstraction rate constants for the 10 model alkanes: ktot is the total rate constant for the abstraction of H atoms from the alkane.

Photochemistry of ozone in a moist atmosphere
TL;DR: In this article, a detailed investigation has been made into the photochemistry of ozone in an atmosphere containing hydrogen, and it is shown that for such an atmosphere a satisfactory ozone profile can be obtained, unlike the situation now existing for an oxygen only atmosphere.
