What is WFEIS?
WFEIS is a web application that provides tools for assessments of historical wildland fire emissions across the US**
WFEIS integrates geospatial burned area, fuel moisture, and fuel loading data layers with the US Forest Service's Consume model to produce emissions inventory estimates.
WFEIS does not provide real-time emissions assessments of active fires, although users can use the calculator to load WFIGS current wildland fire perimeters or submit their own active perimeter data and input estimated fuel moistures for rapid assessment. For near real-time and forecast emissions and plume information, see the US Forest Service's AirFire BlueSky Daily Runs viewer.
**Support for Canada is currently available in beta stage

Updates and versioning history
August 25, 2022WFEIS version rotated to 2.2022.08. Changes include:
- Added LANDFIRE 2020 (v2.2.0) EVT and FCCS basemaps. This affects all US burned areas occuring after 2019-12-31. See July 11, 2022 update note below for REMAP details.
- Added gridMET daily 4-km gridded data, now serving as the default source for CONSUME's 1000-hr fuel moisture inputs for CONUS.
- For the 1000-hr fuel moisture inputs for Alaska and Canada, the method for translating GFWED Drought Code to 1000-hr fuel moisture was updated from the previously used quartile-to-quartile translation. Linear regression analysis produced a more accurate equation that includes latitude as a covariate.
July 11, 2022WFEIS version rotated to 2.2022.07. Changes include:
- Added optimization fix related to running CONSUME for calculator requests; emissions queries should process much faster now than before.
- Added LANDFIRE 2016 (v2.0.0) EVT and FCCS basemaps
- This affects statistics and calculator results for any US fires occuring after 2015-12-31 for both the FCCS and NAWFD fuelbed systems, which prior to this used the LANDFIRE 2014 (v1.4.0) EVT basemap.
- Because the 2016+ FCCS basemaps include representation of disturbed fuelbeds (and consequently lower fuels), emissions results for queries using the FCCS fuelbed system in the US will be significantly lower than in previous WFEIS versions. The following list indicates the overall emissions decreases resulting from the LF v1.4.0 to LF v2.0.0 update for total US fires 2016-2022 for affected burned area sources:
- MCD64A1: -13% (in comparison to LF v1.4.0)
- WFIGS archive: -16%
- NIFS/GeoMAC: -20%
- ABoVE DoB (Alaska only): -30%
- CAL FIRE (California only): -24%
- Queries using the NAWFD fuelbed system will only be affected to the extent that the LF EVT mapping has changed from one LF version to another; there are no disturbance updates like with the FCCS basemap, and so the differences between the current and previous versions should be minor. More information about EVT differences between different LANDFIRE versions.
- LANDFIRE 2020 (v2.2.0) basemaps will be added for >=2020 fires once the AK and HI datasets are ready.
March 9, 2022WFEIS version rotated to 2.2022.03. Changes include:
- Upgraded Consume to FFT v2.0.2028
- Added Wildland Fire Interagency Geospatial Services (WFIGS) archive (going back to 2020) and current (updated daily) perimeters as a burned area source.
October 16, 2020WFEIS 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 emissions results.
August 21, 2020WFEIS version rotated to 2.1 with entirely rebuilt backend and interface.
- Burned area sources now include MODIS MCD64A1, MTBS, GeoMAC, and the option for user-submitted burn perimeters, all updated to include most recent available data.
- Fuelbed system options now include both FCCS as well as the North American Wildland Fuels Database.
- Upgraded from 1-km to 30-m basemaps (US) for fuelbed mapping.
- Upgraded to Consume v5.0
- Global Fire WEather Database (GFWED) fuel moisture data incorporated.
- Initial beta support for Canada added using the Fuel Behavior Prediciton (FBP) Fuel Type map as a basemap with FBP types crosswalked to existing FCCS fuelbeds.
August 6, 2015WFEIS 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.
June 19, 2014Website content updates:
- Added archive of annual WFEIS emissions estimates in various output formats
- A subset of pre-processed annual model runs are displayed on the Examples page
- Added report comparing GFED and WFEIS to Project Outputs page
- Added help for proper encoding of WFEIS URL queries
March 19, 2014WFEIS 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, 2013WFEIS version rotated to 0.3. Associated changes include:
- Burned area datasets added:
- Landsat Daily
- Agricultural NEI
- Smartfire NEI 2011
- Integrated updated Consume 4.1, delivered by FERA
- Added data tables and functionality for calculating agricultural emissions using the Agricultural NEI burned area dataset
