Wildfire smoke plumes transport under a subsidence inversion: Climate and health implications in a distant urban area

[EN] This study shows the influence of two large wildfires (one of which was the largest wildfire ever recorded in the region of Castilla y León) in the north-west of the Iberian Peninsula upon the atmospheric air quality of the city of León, Spain, at approximately 70 km from the fires, on days wit...

The vertical dispersion of the smoke plume was inhibited and this caused an increase in the particulate matter (PM) in the atmosphere. During this event, average values of up to 1700 ± 600 particles cm− 3 were registered, most of which corresponding to the smallest fraction of the fine mode. On the other hand, the count median diameter of the fine mode (CMDf) increased gradually from 0.09 to 0.14 μm. The PM10 and PM2.5 reached hourly values of 89 and 36 μg m− 3, respectively. This study also estimates the changes in the optical properties of the particles as well as the associated radiative forcing. The presence of an important load of absorbing aerosols was detected, with instantaneous radiative atmospheric forcing up to + 134.6 W m− 2. The estimations of the respirable fractions showed in healthy adults high levels of mass concentration of the aerosol that reaches the bronchioles and alveoli (up to 43 μg m− 3)SIThis study was partially supported by the Spanish Ministry of Economy and Competitiveness (Grant TEC2014-57821-R), the University of León (Programa Propio 2015/00054/001) and the AERORAIN project (Ministry of Economy and Competitiveness, Grant CGL2014-52556-R, co-financed with FEDER funds)ElsevierFisica AplicadaFacultad de Ciencias Biologicas y Ambientales2018info:eu-repo/semantics/articleinfo:eu-repo/semantics/acceptedVersionhttps://www.sciencedirect.com/science/article/pii/S0048969717331996https://hdl.handle.net/10612/26121reponame:BULERIA.
