Atmospheric Chemistry Carbon Cycle and Climate

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.

The workshop focused on a future aircraft campaign in the winter of 2021/2022 to investigate wintertime particulate matter in populated mountain basins of the western U.S.

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. The diverse set of new projects ranges from explaining long-term trends in atmospheric composition to supporting resiliency in fishing communities.
