Updated Smoke Exposure Estimate for Indonesian Peatland Fires Using a Network of Low-Cost PM_2.5 Sensors and a Regional Air Quality Model.

ABSTRACT: Indonesia accounts for more than one third of the world's tropical peatlands. Much of the peatland in Indonesia has been deforested and drained, meaning it is more susceptible to fires, especially during drought and El Niño events. Fires are most common in Riau (Sumatra) and Central Kalimantan (Borneo) and lead to poor regional air quality. Measurements of air pollutant concentrations are sparse in both regions contributing to large uncertainties in both fire emissions and air quality degradation. We deployed a network of 13 low-cost PM_2.5 sensors across urban and rural locations in Central Kalimantan and measured indoor and outdoor PM_2.5 concentrations during the onset of an El Niño dry season in 2023. During the dry season (September 1st to October 31st), mean outdo
