Field Burning Fallout: Quantifying PM2.5 Emissions from Sugarcane Fires

[Extract] The authors used PM2.5 measurements from multiple sources to estimate ambient and burning-related exposures. Satellite sensors and ground-based monitoring sites provided daily measurements between 2009 and 2018, covering 10 harvest and 10 nonharvest seasons. They employed the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model to simulate concentrations and dispersion of PM2.5 during the October–March harvest season. Estimates of daily sugarcane fire emissions were based on burn permits issued by the state
