Antarctic ozone hole similar to last year

Antarctic ozone hole similar to last year

The Antarctic ozone hole, which forms annually in the August to October period, reached its peak size on September 11, stretching to 9.3 million square miles (24.1 million square kilometers), roughly the same size as last year’s peak of 9.3 million square miles (24 million square kilometers) on September 16, 2013. This is an area similar in size to North America.

New study explains wintertime ozone pollution in Utah oil and gas fields

New study explains wintertime ozone pollution in Utah oil and gas fields

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new NOAA-led research, published online today in Nature.

Report: telltale signs that ozone layer is recovering

Report: telltale signs that ozone layer is recovering

Nearly 30 years after the protections of the Montreal Protocol were put into place, there’s more evidence that the international agreement to protect Earth’s ozone layer is working, according to a new scientific report released today at the United Nations headquarters in New York.

Encouraging information from this year’s observations of the Antarctic ozone hole

Encouraging information from this year’s observations of the Antarctic ozone hole

For nearly 50 years, scientists with NOAA have launched high-altitude balloons from the South Pole, to understand why a hole was forming in the protective ozone layer high in the atmosphere. Now, organizations around the world track the infamous ozone hole through these ballon-sondes, satellite measurements and ground instruments.

Los Angeles air pollution declining, losing its sting

Los Angeles air pollution declining, losing its sting

The cleanup of California’s tailpipe emissions over the last few decades has not only reduced ozone pollution in the Los Angeles area, it has also altered the pollution chemistry in the atmosphere, making the eye-stinging “organic nitrate” component of air pollution plummet, according to a new study.

NOAA, partners find 50-year decline in some Los Angeles vehicle-related pollutants

NOAA, partners find 50-year decline in some Los Angeles vehicle-related pollutants

In California’s Los Angeles Basin, levels of some vehicle-related air pollutants have decreased by about 98 percent since the 1960s, even as area residents now burn three times as much gasoline and diesel fuel.

A sea change in the Arctic atmosphere

A sea change in the Arctic atmosphere

Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region.
