Short summary

Aircraft measurements are used to study aerosol–cloud interaction, with a focus on three understudied topics (separation of aerosol effects from dynamic effects, dispersion effects, and entrainment-mixing processes). After constraining cloud dynamics, positive correlation between relative dispersion and CCN concentration became stronger, implying that perturbations of dynamics could underestimate dispersion effect. Entrainment mixing is predominantly extremely inhomogeneous in the stratocumulus.
