Thissuggests that insoluble particles larger than 0.4 μmin area equivalent diameter are primarilyremoved at the margin of the rainfall area by wetscavenging processes below clouds in the marineatmosphere in sub-Arctic regions. The frequency ofrain events controls the fate of the troposphericaerosols larger than sub-micrometer in diameter. Reflecting the seasonal long-range transport of Asiandust, mineral particles were dominant as insolubleparticles in the spring rains, but carbonaceousparticles were dominant in the summer rains. Theatmospheric deposition of insoluble particles could besignificant as a source of sediment particles over thesub-Arctic North Pacific.
