Clinical Scorecard: Climate Models May Miss Marine Aerosols

At a Glance

Key Highlights

• Researchers analyzed five years of aerosol measurements collected at Mace Head between 2009 and 2015.
• The measured particle-size distribution included peaks at approximately 60–70 nm and 100–200 nm.
• An established parameterization underestimated marine primary organic aerosol particle numbers above 35 nm by about 3.1-fold, and numbers at 30–70 nm by five- to sevenfold.
• The revised distribution approximately doubled estimated cloud condensation nuclei from these aerosols across representative marine cloud conditions.
• The estimated global-ocean cooling effect was approximately 0.03–0.04 W/m²; the authors described this as a sensitivity analysis, not a complete climate-forcing estimate.
