Researchers supported by AC4 conduct observations over 9 months to examine pollution sources that lead to secondary organic aerosol production in Atlanta.

This new AC4-supported study produces a detailed comparative analysis of oxidation reactions that break down certain molecules into secondary organic aerosols, which impact air quality, climate, and human health.

In winter 2022, about fifty scientists from the United States and Europe completed a seven-week atmospheric chemistry study of Fairbanks, Alaska–the state’s second-largest city. 

The study, called the Alaskan Layered Pollution and Chemical Analysis (ALPACA) project, investigated the chemistry of Fairbanks’s air pollution–especially how the pollution behaves in the cold and dark.

NOAA’s Climate Program Office today launched a newly redesigned version of Climate.gov, NOAA’s award-winning, flagship website that provides the public with clear, timely, and science-based information about climate.

NOAA’s Climate Program Office (CPO) announced today a total award amount of $171 million, the highest five-year investment in the program’s history, to support 72 innovative and impactful projects that will improve our nation’s resilience at a critical time in the fight against the climate crisis.
