Short summary
Organic coatings modify hygroscopicity and CCN activation of mineral dust perticles. Small amounts of oleic acid coating (volume fraction (vf) ≤ 4.1 %) decreased the CCN activity of CaCO3 particles, while more oleic acid coating (vf ≥ 14.8 %) increased the CCN activity of CaCO3 particles, while malonic acid coating (vf = 0.4−42 %) even in smallest amounts increased the CCN activity of CaCO3 particles. Our laboratory results should also hold under conditions of the atmosphere.
