Results demonstrate that AIMACI is not only comparable with conventional schemes in spatial distributions, temporal variations, and evolution of particle size distribution of main aerosol species, including water content in aerosols, but also exhibits robust generalization ability, reliably simulating one month under different environmental conditions across four seasons despite being trained on limited data from merely 16 d.

The scarcity of high-resolution online data for organic aerosol composition and sources, especially in remote areas. The limited knowledge about aerosol mass, chemical composition, and particle number distributions in the marine boundary layer. The uncertainty in radiative forcing estimates due to the lack of understanding of aerosol-cloud interactions.
