Ship Data Show Iodine and Sulfur Chemistry Seeding Arctic Clouds
A five-week Greenland ship campaign found iodine and sulfur acids seeding Arctic particles, then organic vapors grew them into far more cloud-seeding nuclei.
Evidence-based analysis of atmospheric chemistry, oceanography, polar sea-ice dynamics, and geophysical systems. We track climate modeling, aerosol nucleation, and planetary environmental science.
