| Zusammenfassung |
| Simultaneous data on Aerosol Optical Depth (AOD) and size segregated, near-surface,
aerosol mass concentration was obtained from a Multi wavelength
Solar Radiometer (MWR) and Quartz Crystal Microbalance Impactor (QCM),
respectively. These were used to examine the association between near-surface
aerosol properties and columnar AOD. The spectral AODs were
approximated to the Ångström relation τp=βλ-α, and the wavelength exponent α and turbidity
coefficient β have been obtained. In general, α was found to
be well associated with the relative abundance of accumulation mode aerosols
(estimated from the simultaneous QCM data) while β followed the
variations of the coarse mode aerosol mass concentration; the association
being closer during periods of continental airmass. |
