Research Abstract |
we reconstructed past aerosol components recent 720kyrBP by using Dome Fuji ice core. As a result, primary components in soluble aerosols were calcium sulfate and sodium chloride during glacial maximums ; on the other hand, primary components were sodium sulfate during interglacials.
