Abstract The October 2017 Norther California Wildfires were a series of over 250 wildfires across the state of California, resulting in severe environmental and economic loss. This study aims to determine transport of and effects of wildfire emissions based on observed data and chemical transport model. The observational data of meteorology and air pollutants including fine particulate matter (PM2.5) are obtained from California Air Resources Board (ARB) sources. Six stations under direct impact with available PM2.5 data were selected. The Community Multiscale Air Quality (CMAQ) model (v5.2) is also applied with anthropogenic emissions from the National Emissions Inventory (NEI) 2014 using the Sparse Matrix Operator Kernel Emission (SMOKE) model (version 4.5). The fire inventory from National Center for Atmospheric Research (NCAR) is used for emissions of wildfires. Spatial and temporal variations wildfire related air pollutants will also be analyzed and contributions of the wildfires will be quantified. The health and economic effects of the wildfires will also be estimated. This study can provide important information for wildfire-related air quality issues and future health studies.
