Short summary
This study shows with airborne data that in the thin layer above stratocumulus clouds, the entrainment interface layer (EIL), aerosol size distributions are influenced both by new particle formation and by pollutants above and below the EIL. These results are important with regard to understanding aerosol–cloud–climate interactions as the aerosol in this layer can influence the characteristics of stratocumulus clouds, which are the dominant cloud type by global area.
