The organization of the 2014 Football World Cup and the 2016 Olympic Games will attract the world's attention to Brazil. Hence, these events may be a good opportunity to emphasize the air quality challenges to a larger public. Moreover, the 2014 Football World Cup is good case for the air quality modelling team at TNO to test drive their operational air quality forecast system and showcase its ability to monitor and forecast air quality in the Brazilian Midwest and particularly for the states of Rio de Janeiro and Sao Paulo.
For the perspective of air quality Brazil presents a unique feature as it uses biofuels as ethanol and gasohol on a broad scale for fuelling light-duty vehicles. As large scale use of biofuels is considered to combat climate change, studying air quality in Brazil may yield important information on optimizing policies that tackle both climate change and air quality.
At this website we provide initial forecasts air pollution over several Brazilian cities as well as the Brazilian Midwest. For this purpose we use the LOTOS-EUROS chemistry transport model. Based on the meteorological forecast and emission data a forecast for ozone, nitrogen dioxide and particulate matter (PM2.5) is provided for the coming three days.
