Previous issue date: 2011-07-15 / The interference of man in the middle atmosphere can be evidenced by the presence of carbon
monoxide, gas associated with burning fossil fuels and carbon dioxide content, essential for
respiration of plants and thermal balance of the Earth. In this thesis we initially evaluated the
intensity of the spatial distribution of carbon monoxide in the Northeast of Brazil, and
subsequently the behavior of temporal variations of the pollutants carbon monoxide and
carbon dioxide in the atmospheric boundary layer Maxaranguape / RN. Research has shown
that, driven by speculation and promoting the occupation of land for agriculture, cattle
ranching and tourism in the Northeast of Brazil, the changes established by the man in the
middle geomorphological affect the lower troposphere on a large scale, with a predominance
of concentrations in central Pernambuco, Paraiba's south-central and central-west of Alagoas.
However, the study of Maxaranguape / RN results showed little variation in carbon monoxide
and carbon dioxide, with the speed of the wind persisting with values greater than 7.8 m / s,
showing dispersion and diffusion of pollutants which resulted in faster renewal of local
atmospheric air / As interfer?ncias do ser humano no meio atmosf?rico podem ser evidenciadas mediante a
presen?a do mon?xido de carbono, g?s associado a queima de combust?veis f?sseis e do
di?xido de carbono, conte?do fundamental para respira??o dos vegetais e para balan?o
t?rmico da Terra. Nesta disserta??o inicialmente avaliou-se a intensidade da espacializa??o do
mon?xido de carbono no Nordeste do Brasil e, posteriormente o comportamento das varia??es
temporais dos contaminantes mon?xido e di?xido de carbono na camada limite atmosf?rica de
Maxaranguape/RN. As pesquisas mostraram que, motivadas pela especula??o imobili?ria e
promovendo a ocupa??o da terra para a explora??o agropecu?ria e tur?stica no Nordeste do
Brasil, as mudan?as estabelecidas pelo homem no meio geomorfol?gico afetam a baixa
troposfera em grande escala, com predomin?ncia de concentra??es na ?rea central de
Pernambuco, centro-sul da Para?ba e centro-oeste de Alagoas. Entretanto, no estudo realizado
em Maxaranguape/RN os resultados apresentaram pouca varia??o do mon?xido e di?xido de
carbono, com a velocidade do vento persistindo com valores superiores a 7,8 m/s, mostrando
dispers?o e difus?o dos poluentes o que propiciou maior rapidez na renova??o do ar
atmosf?rico local
