Background
In the recent decades Brazil was one of the world's fastest growing major economies and has gained international visibility. The associated increase in industrial activities, transport and urbanization has led to a strong increase in the emissions of air pollutants. Air pollution is associated with severe health effects such as difficulty in breathing, wheezing, coughing, asthma and worsening of existing respiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. Important pollutants are particulate matter, ozone and nitrogen oxides. In mega-cities like Sao Paulo the levels of particulate matter and nitrogen oxide are currently far above the health targets of the World Health Organization.

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.
