(a) Köhler plots for a droplet density of 1,000 cm−3, at T=6°C and 1,013.25 hPa. Curves from top to bottom correspond to 0, 0.5, 1, 2, and 4 p.p.m. initial concentration of gaseous HNO3; Solid lines: Droplets including a 15 nm NH4NO3 core; Dashed lines: Droplets without salt core. (b) Growth of 1,000 cm−3 ternary HNO3–H2O-NH4NO3 particles with a 25 nm dissolved NH4NO3 core. A micrometer-sized diameter is reached within ~1 s or faster.
