Composite Atmospheric Profiling
2021Each observation system that vertically profiles one or several atmospheric parameters by performing in-situ or remote-sensing measurements has its own distinct characteristics in terms of vertical range and resolution, temporal resolution, and height-dependent error.

Atmospheric Composition Change
Atmospheric Environment, 2012Chemically 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 Composition and Surface Exchanges
2004Atmospheric 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

Subarctic atmospheric aerosol composition
2009Subarctic aerosol was sampled during July 2007 at the Abisko Research Station Stordalen field site operated by the Royal Swedish Academy of Sciences. Located in northern Sweden at 68° latitude and 385 m above sea level (m asl), this site is classified as a semicontinuous permafrost mire.

Atmospheric composition during twilight
Advances in Space Research, 1993Abstract A non-steady one-dimensional model for middle latitude of the Earth's mesosphere and lower thermosphere at equinox condition specially adapted for twilight conditions is developed to obtain the temporal dependence of the photodissociation coefficients and the concentration of the different compounds. The temporal variations obtained are used

Subarctic atmospheric aerosol composition
2010Aerosol particles can modify cloud properties by acting as cloud condensation nuclei (CCN). Predicting CCN properties is still a challenge and not properly incorporated in current climate models. Atmospheric particle number size distributions, hygroscopic growth factors, and polydisperse CCN number concentrations were measured at the remote subarctic ...

Nitrogen, oxygen, and argon represent more than 99.9% of the air we breathe. But Earth’s atmosphere hasn’t always had that composition—it is on at least its third distinctive atmosphere. ‘Atmospheric composition’ provides a brief history of Earth’s atmosphere, before considering the two most important regions of the atmosphere for human survival—the ...

Atmospheric Scales of Motion and Atmospheric Composition
2000Weather 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.
