Aerosol Optical Depth At Cape Grim, Tasmania 1986-1999, Stephen R. Wilson, B. W. Forgan

Faculty of Science - Papers (Archive)

The aerosol optical depth at 4 wavelengths (368, 500, 778 and 868nm) has been measured automatically at Cape Grim since 1986. The site, on the northwest tip of Tasmania, Australia was chosen to be representative of much of the southern ocean. Fourteen years of measurement have been calibrated and analyzed. The data have been filtered so that only measurements made under on-shore wind conditions are considered. The major feature observed in the record is the eruption of Mt Pinatubo, which resulted in the aerosol optical depth at 500 nm rising to 0.2 – 0.3. If the period of high stratospheric …
