Resumo: The objective of this research is the analysis of the relationship between air temperature and vehicles CO2 emissions in ABC Paulista urban area, located in the southeast of São Paulo Metropolitan Region. Beside, the temperature projections from two IPCC climatic models were analyzed. The air temperature data in the hourly and monthly time scale were used to identify the intensity of the heat islands. Estimation of vehicular emissions was performed using the EMME traffic simulation model. The results showed that the areas with the highest temperatures are in the northern sector of ABC Paulista, indicating a heat island of medium intensity (3.6 °C). This sector also stood out as the one with the highest CO2 road emission (ton/km) because it presents the most extensive and busiest traffic routes. The climate model projections, despite the uncertainties, indicated a scenario of warmer days and nights, with a rise of 6.3 °C in the maximum annual temperature for the period 2071-2100. The analysis of the geographic distribution of areas with high temperature and high CO2 emissions indicate a contribution of urban traffic emissions to the elevation in air temperature in ABC Paulista, which tends to increase based on IPCC model projection.

Conjuntamente são analisadas as projeções de temperatura de dois modelos climáticos utilizados nos relatórios do Intergovernmental Panel on Climate Change (IPCC). Foram utilizados dados de temperatura do ar na escala temporal horária e mensal, e a estimativa de emissões veiculares foi realizada através do modelo de simulação de tráfego Equilibre Multimodal/Multimodal Equilibrium (EMME). Os resultados mostram que as áreas com as temperaturas mais altas se localizam no setor norte do ABC Paulista, indicando uma ilha de calor de média intensidade (3,6 oC). Este setor também se destacou como o de maior emissão veicular de CO2 em ton/km, por apresentar extensas e movimentadas vias de tráfego. As projeções dos modelos climáticos, apesar das incertezas, indicaram um cenário de dias e noites mais quentes, com um aumento de 6,3 °C na temperatura máxima anual para o período de 2071-2100. A distribuição geográfica das áreas de altas temperaturas e emissões de CO2 sugerem a contribuição do tráfego urbano para o aumento da temperatura no ABC Paulista, a qual tende a crescer conforme projeção do modelo do IPCC.Universidade Federal de Campina Grande - UFCG2018-05-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/9010.22571/2526-433890Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 45-52Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 45-52Acta Brasiliensis; Vol 2 No 2 (2018): Acta Brasiliensis; 45-522526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGporhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/90/44Copyright (c) 2018 Acta Brasiliensisinfo:eu-repo/semantics/openAccessValverde, María Cleoféde Paiva Junior, Humberto2021-07-12T20:04:07Zoai:ActaBra.revistas.ufcg.edu.br:article/90Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:04:07Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false
