Climate change, atmospheric circulation will make for uneven ozone recovery

Earth's ozone layer should eventually recover from the unintended destruction brought on by the use of chlorofluorocarbons (CFCs) and similar ozone-depleting chemicals in the 20th century.

Global structures of DE3 tide

Researchers from LAGEO , the Institute of Atmospheric Physics, has shown that the DE3 tide can propagate up to above 110 km height and exhibits 2-year cycle oscillation. Among all the diurnal tides in the upper atmosphere, this tide is the most prominent component other than the migrating diurnal tide.

ESA tests laser to measure atmospheric carbon dioxide

A recent ESA campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide in the atmosphere. The campaign supports one of the main objectives of the candidate Earth Explorer A-SCOPE mission.

The inaudible symphony analysed

By measuring ‘inaudible’ sounds, events like illegal nuclear tests can be detected. This ‘infrasound’ can also help us understand more about the upper atmosphere, according to KNMI researcher Läslo Evers. Evers will receive a PhD based on his research into this subject at TU Delft on Tuesday 4 November.

Methane gas levels begin to increase again

The amount of methane in Earth's atmosphere shot up in 2007, bringing to an end a period of about a decade in which atmospheric levels of the potent greenhouse gas were essentially stable, according to a team led by MIT researchers.

Air monitoring helps anticipate possible ecosystem changes

When rain settles the atmosphere and brings air pollutants to the ground, it can have a lasting effect on ecosystems, sometimes hundreds of miles away, according to a Texas AgriLife Research agricultural engineer.

Field project seeks clues to climate change in remote atmospheric region

Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface. Findings from the project, based at the National Center for Atmospheric Research (NCAR), will be used by researchers worldwide to improve computer models of global climate in preparation for the next report by the Intergovernmental Panel on Climate Change (IPCC).

Satellites Illuminate Pollution's Influence On Clouds

Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere, where humans live and breathe, because they block the satellite's ability to capture a clear, unobstructed view of Earth's surface. It turns out, however, that these "obstructions" are worth a closer look, as clouds and their characteristics actually serve a valuable role in Earth's climate.
