NOAA teaming up with Arizona firm to advance study of stratosphere

World View Enterprises has offered to carry a miniaturized NOAA instrument on its high-altitude balloon to capture measurements of atmospheric particles on a series of flights in 2021 that will last weeks and cover thousands of miles at altitudes above 55,000 feet.

NOAA exploring impact of COVID-19 response on the environment

NOAA has launched a wide-ranging research effort to investigate the impact of reduced vehicle traffic, air travel, shipping, manufacturing and other activities on Earth’s atmosphere and oceans due to the response to COVID-19.

Healing ozone layer stopped migration of Southern Hemisphere winds

Healing ozone layer stopped migration of Southern Hemisphere winds

A NOAA study published in the journal Nature demonstrates a profound effect of the Montreal Protocol: as levels of ozone-depleting chemicals controlled by the intenational treaty declined, a poleward shift of summertime circulation patterns in the Southern Hemisphere halted.

Ozone hole modest despite conditions ripe for depletion

Ozone hole modest despite conditions ripe for depletion

Weather conditions were ripe for a big ozone hole this year. But declining levels of ozone-depleting chemicals kept it to near-average size.

Emissions of ozone-destroying chemical controlled by Montreal Protocol rising again, NOAA data shows

Emissions of ozone-destroying chemical controlled by Montreal Protocol rising again, NOAA data shows

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.

Possible new threat to Earth’s ozone layer

Possible new threat to Earth’s ozone layer

The Montreal Protocol has been hailed for controlling chlorine-based chemicals that created a vast hole in the ozone layer over Antarctica. But new research by British and American scientists suggest a chemical not controlled by the international treaty poses a potential risk to the Earth’s protective ozone layer.

Rural West sees more smog; now scientists may know why

Rural West sees more smog; now scientists may know why

Ground-level ozone, also known as smog, has climbed in the rural West over the past 25 years, even in such seemingly pristine places as Yellowstone National Park. Now, scientists may have found out why – and why cutting our own output of smog-forming chemicals such as nitrogen oxide hasn’t helped.

NOAA “reels in” data on Utah’s winter ozone problem

NOAA “reels in” data on Utah’s winter ozone problem

A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new NOAA system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas facility emissions to harmful ground-level ozone.

Accounting for Denver’s Ozone

Accounting for Denver’s Ozone

The first peer-reviewed study to quantify oil and gas emissions on Colorado's northern Front Range confirms that energy development is an important contributor to the region’s chronic ozone problem. The NOAA-CIRES research was published August 8 in the Journal of Geophysical Research: Atmospheres

ABOUT US

Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
