Atmospheric Composition and Surface Exchanges

2004
Atmospheric chemistry is a relatively new scientific discipline. Research in this area has intensified dramatically in the last 3–4 decades because of the concerns that growing emissions of pollutants could have severe consequences for humankind. Although the major chemical compounds present in the atmosphere were identified long ago, it is only during

An Introduction to Measurements of Atmospheric Composition

2010
This chapter reviews the basic concepts under the measurements of atmospheric composition. The major challenges are discussed, including the low concentration (usually less than one part per million) of interesting trace gases and the interference among the thousands of species involved in the atmosphere chemistry.

THE COMPOSITION AND STRUCTURE OF THE TERRESTRIAL ATMOSPHERE

1963
Abstract : After a generel description of the various regions of the terrestrial atmospbere, an analysis of physical conditions leading to the knowledge of the heterosphere is given. Molecular dissociation and diffusion in the lower thermosphere are introduced to determine the concentration of various constituents (N2, O2, O, N, He, H).

Atmospheric Composition Change

2012
Chemically active climate compounds are either primary compounds like methane (CH4), removed by oxidation in the atmosphere, or secondary compounds like ozone (O-3), sulfate and organic aerosols, both formed and removed in the atmosphere. Man-induced climate-chemistry interaction is a two-way process: Emissions of pollutants change the atmospheric ...

Atmospheric Scales of Motion and Atmospheric Composition

2000
Weather phenomena occur over a very broad range of scales of space and time, from the global circulation systems that extend around the earth’s circumference to the small eddies that cause cigarette smoke to swirl and mix with clear air. Each circulation can be described in terms of its approximate horizontal diameter and lifetime.

Composition of the Martian atmosphere

Space Science Reviews, 1991
Data on the composition of the Martian atmosphere obtained by instruments aboard the Viking spacecraft are not of sufficient accuracy to address important questions regarding the composition and history of Mars. Laboratory analyses of gases trapped in glassy phases of shergottite meteorite EETA 79001 yield precise data, but it remains to be ascertained

The Composition of Atmospheric Air

1951
For many reasons it is desirable to have a complete knowledge of the composition of the atmosphere as regards both the molecular species present and their absolute quantities. This applies not only to the main components, but also to rare species of polyatomic molecules whose importance in the radiation balance is often quite out of proportion to their
