Resumo: In this study the value of the sulfur dioxide (SO2) total column was assessed, to some of the major metropolitan areas of southern South America (Porto Alegre, Montevideo, Buenos Aires), using data from the sensor OMI (Ozone Monitoring Instrument) for the period 2005-2012. Their annual and monthly variations were investigated using the 99% percentile (P99) for the maximum daily values of the SO2 total column in the planetary boundary layer (PBL). Among the regions analyzed, Montevideo had the highest value of P99 reaching 4,90 DU, being the region more contaminated by SO2 of southern South America. The histograms indicate that the highest frequencies for the three regions analyzed are given in the first four classes of intervals. It was observed increasing values of trend line in the dispersion of the data for the three regions for the same period analyzed.

Foram investigadas suas variações anuais e mensais através do percentil de 99% (P99) para os valores máximos diários da concentração da coluna total de SO2 na Camada Limite Planetária (CLP). Dentre as regiões analisadas, Montevidéu teve o maior valor de P99 chegando a 4,90 UD sendo considerada a região de maior concentração de SO2 da região Sul da América do Sul. Os histogramas indicaram que as maiores freqüências para as três regiões analisadas se dão nos quatro primeiros intervalos de classes. Foi possível observar valores crescentes da linha de tendência na dispersão dos dados para as três regiões para o mesmo período analisado.Universidade Federal do Rio de Janeiro2016-05-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/699110.11137/2015_2_127_136Anuário do Instituto de Geociências; Vol 38, No 2 (2015); 127-136Anuário do Instituto de Geociências; Vol 38, No 2 (2015); 127-1361982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6991/5558Copyright (c) 2016 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNunes, Mateus DiasMariano, Glauber LopesMariano, Ericka Voss Chagas2017-01-23T22:46:08Zoai:www.revistas.ufrj.br:article/6991Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T22:46:08Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
