A State of the Science Review of Wildfire-Specific Fine Particulate Matter Data Sources, Methods, and Models

BACKGROUND: ) are needed for advancing health research, policymaking, and environmental protection. OBJECTIVE: , aiming to improving accuracy and accessibility for health research, policy development, and environmental management strategies. METHODS: estimates for California in 2010 (low fire activity) and 2018 (high fire activity), focusing on Los Angeles (densely monitored) and Modoc (no monitors) counties. Analyses included Pearson correlation, cross-correlation, and Granger causality to assess temporal relationships and consistency. RESULTS: estimates. CONCLUSIONS: increased with wildfire activity. However, limited publicly available datasets hinder comprehensive comparisons and generalizations for health research and outcomes. https://doi.org/10.1289/EHP15672.
