Satellite research reveals smaller volcanoes could cool climate

A University of Saskatchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can ...

Volcanic gases could deplete ozone layer: research

Giant volcanic eruptions in Nicaragua over the past 70,000 years could have injected enough gases into the atmosphere to temporarily thin the ozone layer, according to new research. And, if it happened today, a similar explosive ...

New monitoring system clarifies murky atmospheric questions

A University of Colorado Boulder-led team has developed a new monitoring system to analyze and compare emissions from man-made fossil fuels and trace gases in the atmosphere, a technique that likely could be used to monitor ...

Superconducting submillimeter-wave limb-emission sounder (SMILES)

The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) is the first onboard mechanically cooled superconducting mixer and high-resolution system for measuring atmospheric minor constituents related to stratospheric ...

Nobel scientist who warned of thinning ozone dies

(AP) -- F. Sherwood Rowland, the Nobel prize-winning chemist who sounded the alarm on the thinning of the Earth's ozone layer and crusaded against the use of man-made chemicals that were harming earth's atmospheric blanket, ...

Environment Canada cuts threaten science, international agreements

Recent cuts to the scientific workforce of Environment Canada, a government agency responsible for meteorological services and environmental research, threaten scientific research related to the ozone layer in the upper atmosphere ...

Significant ozone hole remains over Antarctica

The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on September 12, stretching 10.05 million square miles, the ninth largest on record. Above the South Pole, the ozone hole ...

Venus has an ozone layer too: probe finds

(PhysOrg.com) -- ESA's Venus Express spacecraft has discovered an ozone layer high in the atmosphere of Venus. Comparing its properties with those of the equivalent layers on Earth and Mars will help astronomers refine their ...
