Our latest publications address a variety of issues:

Vasconcellos et al (2011) analyze organic and inorganic components, including metals, of inhalable particles in Bogotá, Buenos Aires, and Sao Paulo. In al cities, formate/acetate ratios indicated the strong contribution of photochemical reactions. Analyzes were performed using in a coordinated manner existing laboratories in the various cities.

Saide et al (2011 ) developed an urban scale PM10 and PM2.5 forecasting system that tackles the stable nocturnal conditions and steep topography of Santiago. PM10 and PM2.5 events are effectively simulated using CO as a PM surrogate.Results show that pollution episodes seem to be dominated by previous days emissions. Click here for furhter information.

Gallardo et al (2011) use observed CO to NOx molar ratios to evaluate mobile emissions at four South American cities.CO to NOx molar ratios decrease over the last 10–15 years, mostly due to reductions in CO emissions.The observed ratios are not captured by available inventories.  Major uncertainties are linked to CO emission factors and inadequate activity data for NOx. The evidence indicates overestimates of current NOx emissions. Link to the article here .
