The isotopic composition of atmospheric carbon monoxide

TLDR
In this paper, the isotopic composition of atmospheric CO in the northern hemisphere has been studied and the most likely nature of these sources is discussed and the production rates estimated. But the isotope pattern is different from that for CO from automobile engine combustion, whether compared to combustion in the same region as the air sample or to an estimated world average.

Tropospheric chemistry: A global perspective

TL;DR: A model for the photochemistry of the global troposphere constrained by observed concentrations of H2O, O3, CO, CH4, NO, NO2, and HNO3 is presented in this paper.

Mass-independent isotope effects in planetary atmospheres and the early solar system.

TL;DR: Observed mass-independent meteoritic oxygen and sulfur isotopic compositions may derive from chemical processes in the presolar nebula, and their distributions could provide insight into early solar system evolution.

Compilation of minimum and maximum isotope ratios of selected elements in naturally occurring terrestrial materials and reagents

TL;DR: In this article, the authors present a list of the ranges in isotopic composition and reporting of isotope ratios for different types of isotopes, including water, carbonate and bicarbonate.

The geochemistry of the stable carbon isotopes

TL;DR: A survey of the variation of the ratio C13/C12 in nature can be found in this paper, where Urey and his co-workers used two complete feed systems with magnetic switching to determine small differences in isotope ratios between samples and a standard gas.

Atmospheric oxygen: isotopic composition and solubility fractionation.

TL;DR: Atmospheric oxygen has been found to be enriched in oxygen-18 by 23.5 � 0.3 per mil relative to average ocean water (SMOW) in good agreement with earlier measurements of the solubility effect in distilled water.

Natural sources of atmospheric CO.

TL;DR: The source of atmospheric CO due to CH4 is comparable with, and may be larger than, that associated with the internal combustion engine, and it is argued that CO is more likely.

Gaseous metabolism in lake sediments and paddy soils and the production of atmospheric methane and hydrogen

TL;DR: In contrast to the upland field, the paddy field is usually left under water from late spring to the autumn harvest as mentioned in this paper, and the arable soil changes from an oxidizing to a reducing condition because of microbiological activity.
