Air Quality Tools for Wildland Fire Management in Southern Sierra Nevada

This project aims to enhance regional air quality monitoring in the southern Sierra Nevada region and develop predictive models for assessing the impacts of biomass burning on PM2.5, ozone, and visibility. It involves expanding monitoring networks, implementing mobile monitoring systems, and utilizing the BlueSky modeling framework. Researchers will also develop statistical models to evaluate forecasting precision and predict prescribed fire effects on air pollution. The project collaborates with various institutions and stakeholders to address the needs of wildland fire managers and policymakers.

  4. PROJECT OBJECTIVES 1. Expand existing local networks of air pollution monitors into a regional network useful for spatial modeling of ozone and particulate matter concentration in the southern Sierra Nevada region. 2. Develop and implement mobile monitoring systems to measure ground level pollutant production from multiple fires. 3. Implement BlueSky dynamic modeling system for the southern Sierra Nevada using local topography, weather conditions, and fire history. 4. Develop a statistical model to evaluate the BlueSky model as a forecasting tool for particulate matter from fires and to estimate the precision of its outcome. 5. Develop a statistical model to forecast (with specified precisions) next day or next week prescribed fire effects on regional air pollution (O3 and PM).

  8. What is BlueSky? BlueSky is a modeling framework designed to predict cumulative impacts of smoke from forest, agricultural, and range fires. The BlueSky smoke modeling framework combines state of the art emissions, meteorology, and dispersion models to generate the best possible predictions of smoke impacts across the landscape.
