My FONDECYT (2022-2024)

Integrated Assessment of Air Pollution in Contrasting Geographies of Chile

In April 2022 I will start a 3 year research project, funded by ANID, the Chilean National Research and Development Agency. Below is a summary of what I hope to do.

This project will carry out field measurements of air quality and meteorology in three distinct macro-zones of Chile, the desert north, the central urban and industrial region and the rugged and cold Patagonian south. 


These measurements will be carried out with a suite of air quality instrumentation that are installed in a “mobile laboratory”, a van equipped for accessing fairly remote areas and setting up in chosen locations with a local power supply. Additional small meteorological stations installed on a tall tower and measurement with drones will allow local meteorological experiments to be undertaken close to the measurement station. 

Measurements will be carried out in the North of Chile around Calama and the Alto Loa area (where intensive mining is carried out), in Central Chile in the city of Santiago as well as the industrial zones near Valparaiso and finally, in the Aysén region of Chilean Patagonia, principally centred around the town of Coyhaique, which has a serious domestic wood-burning problem.


Passive sampling instruments will be installed to collect dust samples (in the arid north), rain samples (a rotating rain gauge) and dry deposition of particulate matter and black carbon. These samples will allow a characterization of the composition of the Particulate Matter, showing which metals are present and elucidating the origin of the particles.


The data that is collected will be sent straight to an online database and interactive website where the data can be combined with layers of social or geographical information and compared with meteorological data. This will be linked to the Chilean government´s new Observatorio de Cambio Climático. 


During our various field campaigns and tours through Chile we will carry out science outreach with local residents, invite local researchers to join us in taking measurements and encourage the communities to work on a legacy of long term monitoring projects with low cost or passive sensors that can be left behind. This project will highlight the different atmospheric and air quality phenomena that could lead to potential health effects on local residents and help them to understand how to mitigate these effects and to empower them to keep a closer eye on public policies that may help them.

Scientific Objectives

The main scientific questions this project aims to answer are:

  • How does air pollution vary in its composition and source across Chile?

  • How can mobile measurements or short term campaigns help to fill in the gaps of the monitoring networks?

  • How can we combine low cost sensors, passive collectors and continuous monitoring instruments to get an integrated picture of the air quality and resident´s exposure to pollution in any chosen location?
