  • Abstract Aerosol light absorption ( b abs ) has been measured in real-time in Los Angeles with a validated photoacoustic technique, and its impact on visibility degradation has been examined. These measurements were collected during ten days in the summer of 1987 for the Southern California Air Quality Study (SCAQS). Aerosol b abs ( λ = 514.5 nm) varied from an hourly average value of 7 × 10 −6 m −1 in the 3–4 and 4–5 a.m. periods of 13 July to 9 × 10 −5 m −1 in the 7–8 a.m. period of both 28… CONTINUE READING
