  • Abstract The mass specific optical absorption coefficient (MAC) of Humic-Like Substances (HULIS), isolated from a fine aerosol fraction (PM1) collected at a typical Central European rural background site (Kpuszta) was measured in the re-dispersed aerosol phase at 1064, 532, 355 and 266 nm wavelengths by our recently developed four wavelength photoacoustic spectrometer. It is found to be practically negligible in the visible (0.03 m 2  g −1 @532 nm), while in the ultraviolet (4.9 m 2  g −1 @266… CONTINUE READING
