Event Description
Amazon fires—whether uncontrolled wildfires or intentional burns—produce smoke waves that can blanket the region with unhealthy air for months at a time. These smoke plumes are visible from space and affect the health and wellbeing of millions of Amazonians, yet there is little ground-based data on air quality outside major cities. In this talk, Marcia Macedo will share recent experiences building a ground-based network of low-cost sensors to monitor particulate matter (PM 2.5) at “nose level” over large swaths of the Amazon.
This sensor network, which began as a local project in the state of Acre, Brazil, has grown into a regional grassroots movement that includes Indigenous communities and associations, local universities, civil society partners, and municipal governments. Together, they have deployed hundreds of commercially available low-cost sensors to help fill the large gaps in air quality data for rural areas. This talk will share the story of how this coalition came to be – outlining the technical challenges of maintaining a reliable monitoring network in humid, infrastructure-limited environments, while highlighting emerging opportunities to leverage the data collected to support public health policies and improve fire management.
