I am happy to share our new article, a product of a fruitful collaboration among colleagues in Latin America:
"Carbonaceous fraction in PM2.5 of six Latin American cities: Seasonal variations, sources and secondary organic carbon contribution".
The article can be downloaded from this link:

Following a thread with the highlights of the article:
- Simultaneous harmonized 1-year monitoring campaigns in six LatAm cities provided PM2.5 levels together with EC/OC content.
- The total carbon content showed a relevant contribution to PM2.5 (32 % to 76 %) in all cities.
- EC-tracer method showed that SOC plays a central role in OC (seasonal averages of SOM/TCM from 19 % to 48 %).
- PMF analysis allowed to identify the key role of vehicle emissions, regional biomass burning and SOA in all cities.
- Further research is needed regarding biases in SOA estimation from different methods.
Please share!
