What is WFEIS?

The Wildland Fire Emissions Information System (WFEIS) is a web-based tool that provides users a simple interface for computing wildland fire emissions across CONUS and Alaska at landscape to regional scales (1-km spatial resolution). WFEIS integrates burned area maps along with corresponding fuel loading data layers and fuel consumption models to compute wildland and cropland fire fuel consumption and emissions for user-specified locations and date ranges. The system currently allows for calculation of emissions from fires within the United States (excluding Hawaii and territories) from 1984 through 2013 depending on the selected burned area product.

The WFEIS website allows for two approaches for making fuel consumption and emissions estimates:
  • First, there is an Emissions Calculator that provides a graphical user interface for constructing queries.

  • Second, the WFEIS website responds to queries submitted via properly encoded URL requests (i.e. it implements a RESTful Web API). Examples of valid WFEIS URLs, accessed via the emissions calculator within the KML and text report output formats, can be modified by users and resubmitted to the WFEIS system.
WFEIS is built entirely from open-source software components. Data can be requested and delivered in multiple spatial and non-spatial formats including text reports, CSV, ESRI Shapefiles, KML documents, GeoTIFF images, and netCDF files.

More information can be found on the Project Outputs page.

Updates and versioning history

June 19, 2014

Website content updates:

March 19, 2014

WFEIS version rotated to 0.4. Associated changes include:
  • 1-km MODIS-enhanced FCCS added and set to default fuels layer
  • Upscaled 1-km Cropland Data Layer-based fuels map added for optional inclusion of agricultural emissions estimates
  • More information on how WFEIS incorporates both fuel layers can be found on the WFEIS Fuels Map page.
  • Fuel moisture is now based on 40-km gridded estimates from RAWS data rather than interpolation to CEC level II ecoregion

October 2, 2013

WFEIS version rotated to 0.3. Associated changes include:
  • Burned area datasets added:
  • Integrated updated CONSUME 4.0 delivered by FERA
  • Added data tables and functionality for calculating agricultural emissions using the Agricultural NEI burned area dataset
