Better understanding of how ozone, an air pollutant and greenhouse gas, is removed is essential for improved modeling and prediction of air pollution, ecosystem health, and climate.
New research provides unprecedented synthesis of how ozone is removed at Earth’s surface Read More »
Methane is the second most important anthropogenic greenhouse gas in the atmosphere after carbon dioxide, with U.S. oil and natural gas supply chain methane emissions, in particular, making up about 41% of anthropogenic emissions in the United States.
The new research in Nature Geoscience suggests that global budget estimates of ozone-depleting substances as well as other trace gases like methane could be improved by accounting for the Quasi-Biennial Oscillation’s influence.

Accessible via the Oak Ridge National Laboratory Distributed Active Archive Center, the database provides the most detailed estimates available of where CO₂ is emitted from within the transportation sector and will help scientists and decision makers track how CO₂ emissions are changing over time and across U.S. cities.
Agricultural activities are the main source of nitrous oxide emissions from human activities, but there is limited attention to agriculture as a major contributor to increasing emissions likely from a lack of understanding of mechanisms controlling nitrous oxide emissions.

On December 4, Colm Sweeney, Aircraft Program lead for the NOAA Global Monitoring Division Carbon Cycle Group and Acting Deputy Director for CPO’s Ocean Observing and Monitoring Division, will present results from an intensive airborne campaign to measure levels of methane, carbon dioxide, carbon monoxide, and ethane emissions from five major cities along the East Coast.

NOAA’s Atmospheric Chemistry. Carbon Cycle, and Climate (AC4) Program is funding 10 new 3-year projects that aim to explain trends, patterns and extremes detectable in the existing long – term observational records of atmospheric composition. The competitively selected projects total $5 million over three years, including $4 million in grants and $1 million in other
NOAA’s Climate Program Office (CPO), part of NOAA’s Office of Oceanic and Atmospheric Research, is announcing a total of $22.8 million in competitive awards to support 62 new projects 1. The diverse set of new projects ranges from explaining long-term trends in atmospheric composition to supporting resiliency in fishing communities. Universities and other research institutions spread
The November 18-19 workshop will bring together stakeholders and scientists to identify opportunities for ESSM’s programs to support climate research that enhances resilience to extreme heat.
