Some aerosols characteristics on Camagüey
Main Article Content
Abstract
The measurements of the aerosols optical characteristics carried out in the center of Camagüey city of (CMW) and the Meteorological Center (CMP), which are about 8 km away, are analyzed. A total of 3099 observations were taken irregularly between February from 2011 and December 2016, using a Microtops II manual sunphotometer. The average aerosols optical depth (AOD), in the 500nm for the rainy period, was 0.18 ± 0.10 in the CMW and 0.16 ± 0.10 in the CMP, while in the dry season they were 0.12 ± 0.06 and 0.10 ± 0.09 respectively. Fine aerosols predominate over the city in the rainy season, but not in the dry season, where aerosols of the coarse mode are more abundant. In the CMP there is a balance between both modes of aerosols. The different types of particles present on the measurement sites were discriminated, the analysis revealed that there is a predominance of aerosols of marine origin in both the CMW (54%) and the CMP (68%) while the mixed aerosols constitute the 35% and 23% respectively. In addition, in the city 7% of the aerosols are of urban / industrial origin and the rest (4%) are of dust, the aerosols of urban / industrial origin constitute only 4% in the CMP and those of dust the 5%.
