| 英文摘要 | We investigated aerosol hygroscopic growth property and its influence on scattering coefficient using m9003 nephelometers in coupling with humidity controlled inlet system at a rural site near beijing mega-city from 24 april to 15 may 2006. inlet relative humidity was controlled in an increasing range of 40%-90% while aerosol hygroscopic growth factor of scattering coefficient, f (rh=80%) as ratio of scattering coefficient at rh=80% to "dry" scattering coefficient (rh<40%) varied in a range of 1.07-2.35 during the measurement. further analysis indicated that under dust episode, measured f (rh=80%) is 1.2 +/- 0.02, and estimated periodic mean value of f (rh=80%) was 1.31 +/- 0.03 under clean periods; during urban pollution periods, the aerosol displayed relative strong water absorbing properties with f (rh=80%) of about 1.57 +/- 0.02. an examination of chemical composition of daily filter samples highlighted that aerosol hygroscopicity was generally depressed with the increasing ratio of organic matter (omc)/ammonium sulfate (as) in particle mass, similar with the results of many previous studies. however, a special case with high value of f (rh=80%)=2.21 and high omc/as ratio was also observed, this exception reflected physico-chemical particularities of organic matter and its complex interaction with other compounds during this episode. |
