Balderas López J.L. del Río Correa Física, Astronomía y Matemáticas multifractal spectra time series analysis Atmospheric pollution Atmospheric pollution is an important problem in the Metropolitan Zone of Mexico City (MZMC). Concentrations of ozone, sulfur dioxide, carbon monoxide, nitrogen dioxide and PM10 particles (smaller than 10 micrometers) have been measured in approximately thirty monitoring stations in different places of the City since 1986, although the data before 1990 are not very confident. The concentration was measured on an hourly basis. In this work we have analyzed with multifractal analysis the concentration time series of atmospheric pollutants since 1990 to 2005. We applied the Chhabra and Jensen multifractal formalism to the analysis of some MZMC air pollutants time series. We find that these series are multifractal, which reveals a new level of complexity distinguished by the wide range of necessary fractal dimensions to characterize the dynamics of air pollutants time series. We discuss the relevance of this fact. 2013 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57030970002 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
