Short summary

This study measured the compositions and mixing states of individual aerosol particles collected at different altitudes over the western North Pacific by simultaneous sampling from an aircraft and a research vessel. The results showed that they were strongly influenced by Siberian Forest biomass burning and mixed with sea spray, and various aerosol compositions were identified at different altitudes, sizes, and aerosol sources, highlighting a wide range of individual particle compositions.
