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.
