Backscatter and Transmission of Aerosol at UV Through Middle IR wavelengths
Abstract
Simultaneous direct measurements of volume extinction, Omega sub e, and backscatter coefficient, Omega sub b, for obscuring aerosol of carbon graphite flakes have been carried out in the laboratory at four wavelength 1064, 532, 355 and 266 nm. Despite the low backscattered signal, reasonably good agreement was obtained between the experimental values for Omega sub e/Omega sub b and theoretical-values (for spheres). The total pollen and spore concentration, per cu m, at Mace Head field station on the west coast of Ireland, is presented for the months of June, July and August 1993. Individual species concentrations are also presented. Measurements of pollen and spore species in units of grains per area, using an array of passive samplers (Tauber Traps) for seven sites in the west of Ireland are also shown, covering the period from November 1992 through September 1993.
