Development of decision products for spatial quantification of carbon emissions from wildfires for North America
A major goal of the North American Carbon Program is to resolve uncertainties in understanding and managing the carbon cycle of North America. As carbon modeling tools become more comprehensive, accurate datasets to spatially quantify carbon emissions from fire are needed. Dr. Nancy French, of the Michigan Technological University, Michigan Tech Research Institute (MTRI) has teamed with specialists at the USDA Forest Service Pacific Northwest Research Center’s Fire and Environmental Research Applications (FERA) lab to provide information for mapping fire-derived carbon emissions by adapting existing Forest Service fire information products and tools using NASA data and products. This work extends previous research of Dr. French’s sponsored by NASA's New Investigator program.
The Goal of the proposed project is: To develop improved products for modeling and estimating fire emissions across North America and implement a prototype information system for disseminating this information to users who manage carbon or model the carbon cycle.
Estimating fire emissions from ground-based data requires calculation from four parameters (Figure 1; French et al. 2004): area burned, fuel loading (biomass per unit area), fuel consumption (fraction of biomass consumed), and emission factors (mass of a given chemical species emitted per mass of fuel/biomass consumed). The project planned will collect data for all of these factors so information users will have the latest and most accurate data for use in models and emissions estimations.

The information will be provided at a 1 km spatial resolution and have relevance for understanding fire-affected carbon cycling at regional scales for the North American continent. Products and results will be consistent across international borders, although product reliability will inevitably vary due to availability of field and remote sensing data needed to create and validate the products.
MTRI will develop an interactive, on-line geospatial information system that pulls together fire location data with corresponding fuel consumption and fuel loading data layers for fuel emission modeling. The geospatial data system will be built from open-source software components that work with open international standards developed by the Open Geospatial Consortium (OGC) such as Web Mapping Service (WMS) and Web Feature Service (WFS) in order to facilitate future enhancements to the system.
The information system will provide access to data representing all four of the data layers needed for estimating fire emissions (see Figure 1). Information products will be provided as GIS-based and tabular products at a 1-km cell-size covering North America, including Alaska, Canada, the conterminous United States, and Mexico. The proposed project will provide the most up-to-date versions of the data layers in the Wildland Fire Emissions Information System (WFEIS). The fuel loading maps will be improved for the US and extended to all of North America based on the procedure employed to map the conterminous US by Co-I McKenzie (McKenzie et al 2007; Ottmar et al. 2007). Fuel consumption will be estimated by employing the CONSUME 3.0 fuel consumption model in the US and Mexico; emissions will be estimated with the Canadian Forest Service’s BORFIRE model for Canada (de Groot et al. 2007).
