Bilateral collaboration in Brasil

Levels of particles

With the help of Chilean experts and experience gained from the collaboration with Chile, SMHI has carried out a pilot project in the town of Sapiranga in Rio Grande do Sul in the south of Brazil. Levels of particles in the air were estimated by measuring and modelling. Results from the project indicate that particle levels in a small town like Sapiranga may be high due to wood burning, among other things. It is important that this problem is noticed and measures are taken, so that attention is not only given to pollution in large cities. The project was mostly carried out in 2014 and the final report was submitted in March 2015. It has received a lot of attention in the state.

Since 2015 SMHI have collaborated with governmental agencies and the University in the city of Curitiba in a project with similar focus on particles and soot. One thing that is different is that Curitiba is a multmillion city and the capital city of the region of Paraná. In the project, called ParCur (Particels in Curitiba), a measurement campaign was performed during some winter month in 2016. The first phase, with focus on emission sources of particles and soot, will be reported during 2017.
