Burned area products provide:•burn area•location -> tells us fuel loadings, fuel moisture•day -> tells us fuel moisture

Options:•MODIS MCD64A1•MTBS burn perimeters•Daily progression (MODIS Active Fire interpolated to MTBS)•SmartFire 2011 NEI•Agricultural NEI (McCarty)



Fuel type (from 1-km FCCS map) linked to stratified fuel loadings (biomass)



Daily gridded weather •Daily fuel moisture interpolated from RAWS data from 1986 through 2013 at 40-km scale for all of CONUS

Main Project ObjectivesMain Project Objectives

• Improve WFEIS• Improve inputs: fuel loading (biomass), fuel moisture

• Develop methodology for uncertainty measurement for emissions estimations

• Produce regional emissions estimates

• Compare these estimates to CASA GFED estimates

Objective Objective

Improve WFEIS inputsImprove WFEIS inputs

aggregated classes

Biomass varies across instances of each class

Refining the fuels map for CONUSRefining the fuels map for CONUS(Co-I McKenzie)(Co-I McKenzie)

Each instance of a class (cell) is assigned a unique set of fuel loadings.


We can use remote sensing products to help to more appropriately characterize canopy fuels and thus provide fuel load variation within a single fuel type

Canopy fuel loadings in forested fuelbeds are generally lower. Exceptions in northern Rocky Mts, Northeast, Gulf coast, upper Michigan.

As expected, spatial variation is more “realistic” in MODIS-enhanced fuel layer.

Before: -by Level II CEC Ecoregion

Now: -by 40 km grid cell (interpolated from RAWS)

“Improved” = •better spatial resolution•updated through 2013

Develop methodology for assessing Develop methodology for assessing uncertaintyuncertainty

Achievements: – Developed a framework for estimating the various

components of WFEIS model uncertainty– Mathematically rigorous documentation of the (~60)

Consume regression equations– Identified all possible sources of error:

• Coefficient error for each regression-based prediction equation • Input measurement error (e.g. measurements from field work)• Classification error (e.g. accuracy of spatial data)

Provide Assessment of Uncertainty Provide Assessment of Uncertainty in Emissions Estimatesin Emissions Estimates

Achievements:

– Conducted case studies on two of Consume’s regression-based consumption equations

– The two studies were done for the shrub and for the western woody fuel strata

– These examples demonstrated both sample-based and Monte Carlo approaches to uncertainty and sensitivity analysis.

Region 11 – Mediterranean CaliforniaThis is the only ecoregion in the continental US with a Mediterranean climate – summers are hot and dry, and winters are mild. Droughts are common, with precipitation averaging from 200-1,000 mm per year. With irrigation, these features create a prime environment for high value agriculture. Native vegetation is dominated by shrubs, with patchy areas of grasslands and forests of evergreen and deciduous trees.

Compare to CASA GFED estimatesCompare to CASA GFED estimates

GFED comparison to WFEIS GFED comparison to WFEIS (with collaborator Collatz)(with collaborator Collatz)

Comparison between GFEDv3 (published emissions) and WFEISv0.3 for TENA/CONUS 2001-2010

GFEDv3 is the fire emissions module in CASA-GFED, one of the models used in the CMS-Flux pilot for terrestrial C flux estimates


Summary of differences between major model components


Modeled emission results comparison– Carbon: GFED ~50% of WFEIS


Modeled emission results comparison– CO2: GFED ~95% of WFEIS

Project is complete, BUT we are currently seeking funding for the continued development/maintenance of WFEIS and are eager to get to work on the following important tasks:

– Full uncertainty characterization of the CONSUME model• Started under this project; statistical framework established and

demonstrated test cases for several of the ~60 consumption equations

• Once complete, the end goal is for WFEIS outputs (and any other modeling effort making use of the CONSUME model) to deliver uncertainty estimates

The Road AheadThe Road Ahead

Project is complete, BUT we are currently seeking funding for the continued development/maintenance of WFEIS and would love to get to work on the following important tasks:

• Integrate information on land disturbance from remote sensing and other geospatial products to update dynamically the representation of fuel loadings in WFEIS


Project is complete, BUT we are currently seeking funding for the continued development/maintenance of WFEIS and would love to get to work on the following important tasks:

• Develop international versions of WFEIS
