Abstract In order to obtain a better understanding of the behavior of aerosols and SO2 in the longrange transport through a marine boundary layer, a simple box-model is applied to the evaluation of the residence times of the species from the concentrations of gases and aerosols measured simulataneously on two islands in the West Pacific Ocean in the north-west monsoon. For Aitken and large particles, the residence time is varied from 3.7 to 7.4 days depending on the particle size, and their flux to the sea is equal to or slightly smaller than that of the free atmosphere. The residence time of giant particles is about one day and their flux to the sea is three times larger than that of the free atmosphere. The residence time of SO2 is 15 hr, and the relative SO2 mass flows of the deposition to the sea, of the diffusion to the free atmosphere and of the transformation to SO4 2- are approximately 4, 1 and 1, respectively.
