What is WFEIS?

WFEIS is a web-based tool that provides users a simple interface for calculating wildland fire emissions across the US and Canada (beta). WFEIS integrates geospatial burned area, fuel moisture, and fuel loading data layers with the US Forest Service's Consume model to calculate emissions for user-specified locations and date ranges.

WFEIS is built entirely from open-source software components. Data can be requested and delivered in multiple spatial and non-spatial formats including JSON, CSV, and ESRI Shapefiles.

More information can be found on the Project Outputs page.

Updates and versioning history

October 16, 2020

WFEIS version rotated to 2.2020.10. Changes include:
  • Changed system name from Wildland Fire Emissions Information System to Wildland Fire Emissions Inventory System.
  • Upgraded Consume to FFT v2.0.2017
  • Added CAL FIRE FRAP burn perimeters.
  • Added stats page for display of pre-calculated model runs.

August 21, 2020

WFEIS version rotated to 2.1 with entirely rebuilt backend and interface.

August 6, 2015

WFEIS version rotated to 0.5. Associated changes include:
  • Added JSON as optional output format.
  • Example for Colorado, 12-15-11 to 12-30-11, SmartFire2 burned area.
  • Updated to Consume 4.2 (details)
  • Notably, this update of Consume 4.2 features corrected emissions factors. Previous versions of Consume (and by extension, WFEIS), used some emissions factors with incorrectly specified units (g/kg instead of lb/tons), and so while consumption outputs were valid, emissions outputs were underestimated by roughly one half (e.g. a reported value of 10 kg CO2 should actually have been around 20 kg CO2).
  • The FCCS fuelbeds affected by this unit correction comprise 71% of total area burned (MCD64A1), 81% of fuel available within those burned areas, and 82% of total fuel consumption across CONUS for 2001-2013. Unaffected fuel types include shrub/chaparral types exclusive to CONUS and predominantly found in the southwest US.
  • The archive and examples pages have been updated with regenerated results that use these corrected emissions factors. Updated results can be found in the "v05_2015-08-01 directory. The previously generated results can still be found in the archive under the "v04_2014-06-01" directory.

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 4.1, delivered by FERA
  • Added data tables and functionality for calculating agricultural emissions using the Agricultural NEI burned area dataset
