Characterization of aerosol particle episodes in Finland caused by wildfires in Eastern Europe
We studied the sources, compositions and size distributions of aerosol particles during long-range transport (LRT) PM2.5 episodes which occurred on 12–15 August, 26– 28 August and 5–6 September 2002 in Finland. Backward air mass trajectories, satellite detections of fire areas and dispersion modelling results indicate that emissions from wildfires in Russia and other Eastern European countries ...
متن کاملObservations of smoke-influenced aerosol during the Yosemite Aerosol Characterization Study: Size distributions and chemical composition
[1] The Yosemite Aerosol Characterization Study (YACS) took place in Yosemite National Park from 15 July to 5 September 2002, during which time air masses arriving at the site were believed to have been influenced by smoke from numerous wildfires active in the western United States. Physical, optical, and chemical aerosol measurements were made to characterize visibility and to help define aero...
متن کاملInteractive comment on “Retrieval of aerosol absorption properties using the AATSR satellite instrument: a case study of wildfires over Russia
The basic premise behind the retrieval is to iterate the mixing ratios of two aerosol models for each size mode. (Weakly and a strongly absorbing aerosol models are used for the fine mode, sea salt and dust models are used for the coarse mode.) Ideally, the retrieval will produce the mixing ratios that best describe the measured radiances at 3-4 wavelengths. (The mixing ratio of dust and sea sa...
متن کاملInvestigating the relationship between ground-level particulate matter and aerosol optical depth during dust storm episodes: a case study of Tehran
Background and Objective: During the last few years, air pollution and increasing levels of particulate matters (PMs) have become major public health issues in the megacity of Tehran. The high cost of constructing and maintaining air pollution monitoring stations has made it difficult to achieve adequate spatial-temporal coverage of PM data over various regions. In this regard, the use of remot...
