A INFLUÊNCIA ANTRÓPICA NA EVOLUÇÃO SEMANAL DA TEMPERATURA DO AR NO BAIRRO MARACANÃ/RJ

This paper aims to study the urban climate in the quarter Maracana, considering its environmental characteristics, patterns of land use and dynamism of the activities subject to regional atmospheric patterns acting, able to reflect on a weekly evolution of air temperature. The daily data of temperature of the meteorological station of the Maracana, from 1992 to 2002, were separated by day and compared with data for three tracking stations air quality in neighboring districts – Sao Cristovao and Tijuca, in addition to the Center. The evaluation human influence on this pace was made in two stages: the first was made at the intersection of the curve of temperature with the concentration of CO to evaluate the interference of vehicles in temperature; already the second step was the warming caused by an agglomeration of people through data loggers installed in the stadium Maracana monitoring the air temperature for a week, and that time was a public event with a more than 50 thousand people, the first game of end of the Copa do Brasil, 2006 when they faced Vasco and Flamengo. The four monitoring stations showed a weekly rate for a similar temperature, with warmer days and the weekends less hot. However, no evidence of anthropogenic interference in this weekly rhythm.
