A recent study supported by AC4 and COM investigates emissions of the greenhouse gas with the largest known warming potential, updates the understanding of how much we have in the atmosphere, and proposes possible solutions for reducing emissions.
A recent FIREX-AQ study supported by AC4 analyzed emissions and revealed region-specific chemical signals during a controlled burn in the understudied region of Northern Michigan.
A new AC4-supported study published in Nature Communications provides pioneering results on the complex formation of secondary organic aerosol air pollutants.
A report was published in BAMS on an AC4 and ERB workshop with stakeholders and end users with diverse backgrounds in atmospheric science to provide the state of the science and user needs for operational atmospheric composition measurements to inform future NOAA Low Earth Orbit satellite missions.
A recent study supported by AC4 uses modeling methods to improve long-term observational records, confirming an understood trend of decreasing ozone in the lower stratosphere and challenging previous work showing a positive trend in the upper stratosphere.
