Stratospheric ozone depletion through catalytic chemistry involving man‐made
chlorofluorocarbons is an area of focus in the study of geophysics and one of the global …

Abstract The eruption of Mt Pinatubo in June 1991 caused the largest perturbation this
century to the participate content of the stratosphere. The radiative influence of the injected …

For the past 3.8 billion years, the geochemistry of the Earth's surface-its atmosphere, waters
and exposed crust-has been determined by the presence of biota. Photosynthetic organisms …

Stratospheric ozone levels are near their lowest point since measurements began, so
current ultraviolet-B (UV-B) radiation levels are thought to be close to their maximum. Total …

Spectral measurements of ultraviolet-B radiation made at Toronto since 1989 indicate that
the intensity of light at wavelengths near 300 nanometers has increased by 35 percent per …

Previous studies on ice core analyses and recent in situ measurements have shown that
CH4 has increased from about 0.75–1.73 μmol/mol during the past 150 years. Here, we …

Das vorliegende Buch verfolgt zwei Ziele. Es dient zunächst der Einführung in die
allgemeine Physik der Atmosphäre und macht das Funktionieren des Systems Atmosphäre …

Since 1988, the distribution of carbon monoxide (CO) in the lower troposphere has been
determined using a globally distributed air sampling network. Site locations range from 82° …

Ozone plays a very important role in our atmosphere because it protects any living
organisms at the Earth's surface against the harmful solar UVB and UVC radiation. In the …

Simulations of the stratosphere from thirteen coupled chemistry‐climate models (CCMs) are
evaluated to provide guidance for the interpretation of ozone predictions made by the same …
