CORTES-HERNANDEZ, Virginia Edith y APARICIO, Javier. Characterization of biomass burning aerosols over southeast Mexico. Tecnol. cienc. agua [online]. 2014, vol.5, n.1, pp.145-156. ISSN 2007-2422.
Characterization of aerosols is important for the atmospheric radiative process and the radiation budget of the climate system. This study presents some physical properties forming part of the optical and radiative characterization of atmospheric aerosols measured in two monitoring sites from the AERONET network located in Southeastern Mexico during 2005-2007. The location of both sites corresponded to the region of high biomass burning activity during 2005. Characterization of aerosols considered four study cases: 1) April 23, 2005 in Tenosique, Tabasco, 2) April 27, 2005, 3) May 8, 2006 and 4) May 24, 2007 in Tuxtla Gutierrez, Chiapas. Results show values of high atmospheric optical depth (τ > 1.4), fine accumulation mode particles (r < 0.34), single scattering albedo (ω0~1), as well as low values of refractive index complex (k ~ 0), as a result of an interaction between solar radiation and smoke aerosols mainly due to scattering over the southeastern Mexico.
