Observations show increased nitrate in coastal cloud droplet residuals from large-particle activation and N 2 O 5 hydrolysis

Clouds change the chemical composition of aerosols, yet observations characterizing these processes are quite limited. Ground-based in-cloud measurements in coastal Southern California show that the highest nitrate to sulfate ratio (2.5 ± 1.7) in droplet residuals is near cloud b...
