Two additional regions of Asia were sources of banned ozone-destroying chemicals

A follow-up investigation by NOAA scientists into the sudden increase in emissions of an ozone-destroying chemical between 2010 and 2018 has determined that three regions of Asia - not just one - were responsible for rising emissions of the banned chemical.

Former GML Director James Butler retires

Dr. James Butler, Director of NOAA’s Global Monitoring Laboratory (GML), retired on December 31, 2021 after 35+ years of service to NOAA and the global scientific community.

Fires are driving short-term spikes in an ozone-depleting gas

New research reveals global wildfires as an important cause of the short-term spikes in the atmospheric abundance of a potent ozone-depleting chemical, methyl bromide.

A potential application of a low-cost sensor in global aerosol monitoring

New research evaluates the use of a low-cost, widely-used PurpleAir sensor to estimate aerosol light scattering properties.

A new site is installed for the NOAA Federated Aerosol Network

The Barrow Atmospheric Baseline Observatory revitalization project is coming to an end

Demolition of the original laboratory building at GML’s Barrow Atmospheric Baseline Observatory began on October 15, ending its almost 50 years of service since 1972. The demolition of the original laboratory building is the last part of the Barrow Atmospheric Baseline Observatory revitalization project.

A Window on the World

For nearly 50 years, NOAA’s Barrow Atmospheric Baseline Observatory has provided a window on the world, producing a record of changes at the U.S.'s northernmost tip that have a profound global reach.

NOAA data shed new light to improve NASA satellite products for carbon dioxide

New research shows that systematic errors in the OCO-2 total column CO₂ products can be large enough to confound reliable surface flux estimation.

Atmospheric carbon dioxide rebounds as global pollution rates approach pre-Covid levels

Global carbon emissions are projected to bounce back to 36.4 billion metric tons this year after an unprecedented drop caused by the response to the coronavirus pandemic.

Urban areas across the U.S. are undercounting methane emissions, a new study shows

An eight-year study of Boston’s natural gas system has revealed that emissions of methane, a powerful greenhouse gas, are significantly higher than previously estimated.
