COVID-19 Lockdowns Reduced Ozone Pollution Over the Northern Hemisphere

During COVID-19 shutdowns last year, ozone levels in the lower atmosphere fell by seven percent across much of the Northern Hemisphere, according to a new study.

Large, deep Antarctic ozone hole to persist into November

Persistent cold temperatures and strong circumpolar winds supported the formation of a large and deep Antarctic ozone hole that will persist into November, NOAA and NASA scientists reported today.

NOAA marks 40 years of ballon-borne water vapor measurements

In April 2020, the Global Monitoring Laboratory’s measurement record of upper atmospheric water vapor over Boulder, Colorado, surpassed 40 years in length.

2019 ozone hole smallest on record

Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982.

Ozone hole modest despite conditions ripe for depletion

The ozone hole that forms in the upper atmosphere over Antarctica each September was slightly above average size in 2018, NOAA and NASA scientists reported today.

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.

Warm air helped make 2017 ozone hole smallest since 1988

Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced today.

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.

Fifty years ago, a historic balloon launch that changed the way we see the ozone layer

What started out as a modest research project driven by scientific curiosity provided the agency that would later become NOAA with some of the first insights into how ozone was distributed in the atmosphere.

Antarctic ozone hole about average in 2016

The hole in the Earth’s ozone layer that forms over Antarctica each September grew to about 8.9 million square miles in 2016 before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon.

4 ways the ozone hole is linked to climate, and 1 way it isn’t

To mark the peak of ozone hole season, we’re highlighting four ways that climate and the ozone hole are related—and one important way they aren’t.

Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection (POSIDON) Experiment

The NASA Pacific Oxidants, Sulfur, Ice, Dehydration, and cONvection (POSIDON) Experiment is a focused airborne science mission to study the ozone distribution, sulfur chemistry, very short-lived ozone depleting species (VSLS), cloud microphysics, and dehydration in the tropical upper troposphere and lower stratosphere over the western Pacific.

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.

Robert (Bob) D. Evans of ESRL Global Monitoring Division receives the prestigious IO3C Farman Award Nomination

Robert (Bob) D. Evans of ESRL Global Monitoring Division receives the prestigious IO3C Farman Award Nomination For Sustaining a Long-term Inter-calibrated World-wide Dobson Total Ozone Observing Network. The "Joseph C. Farman Award" is granted to one or more outstanding scientists who have created and used high-quality, long-term time series of atmospheric measurements related to the study of atmospheric ozone and/or surface ultraviolet radiation.
