Advancing scientific understanding of climate, improving society’s ability to plan and respond
Researchers funded by AC4, MAPP, and NIDIS publish a comprehensive report on the relationships between air pollution and weather/climate extremes such as extreme precipitation, floods, droughts, wildfires, and heat waves, calling for interdisciplinary collaborations and enhanced observational and modeling capabilities.
NOAA’s Climate Program Office announced a total annual award of $11.4 million in Fiscal Year 2023 funding to support 24 new, innovative, and impactful projects that will improve our nation’s resilience at a critical time in the fight against the climate crisis.

AC4-funded research team publishes a review paper on the hydroxyl radical (OH), a critical self-cleansing molecule that helps maintain air quality.
Results from FIREX-AQ research supported by AC4 analyzes measurements from a ground-level mobile laboratory close to the fire source to show that wildfire emissions are vastly heterogeneous and have significant discrepancies when measured at ground-level compared to by aircraft.
