AC4 and ERB in collaboration with NESDIS is organizing a workshop to better understand the needs of atmospheric composition applications and gather recommendations for future UV-Vis-NIR data from the low-earth orbiting (LEO) NOAA satellite missions.

For the first time, the U.S. Environmental Protection Agency (EPA) has included a comparison of NOAA’s atmospheric emission estimates of four hydrofluorocarbons (HFCs) to its own inventory-based estimates in the just-released U.S. Inventory of Greenhouse Gas Emissions and Sinks, based on results first reported in the 2017 Geophysical Research Letters study by a team of NOAA, CIRES, and EPA scientists.
These urban mitigation policies aimed at reducing CO2 emissions can worsen air quality and cause premature deaths if coemitted pollutants are not accounted for.

New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.

A new study funded by CPO’s AC4 program expands our understanding of the composition and sources of Arctic organic aerosols.
The research, co-authored by GML scientists and funded in part by CPO’s AC4, narrows the gap between known sources and sinks of methyl bromide.

New research reveals the contribution of ⍺-pinene + NO3 in the secondary aerosol budget, and likely constitutes a major removal pathway of reactive nitrogen from the lower troposphere.
Drought conditions lead to an increase in summertime ozone in the U.S. Southeast but not the West, highlighting the long-term impact of droughts on atmospheric composition.
