Biomass burning emissions
This page describes the options for biomass burning emissions in GEOS-Chem.
The GFED4 biomass burning emission inventory is now the current default biomass burning dataset for GEOS-Chem (introduced in v10-01, June 2015). The current GFED4 archive contains data from 1997 through 2016.

I developed the FIRECAM tool for end-users to quickly compare fire emissions estimates from five global inventories (GFEDv4s, GFASv1.2, FINNv1.5, QFEDv2.5r1, and FEERv1.0-G1.2) for a given study region. Currently, FIRECAM supports six species: CO2, CO, CH4, OC, BC, and PM2.5. FIRECAM compares the five inventories at an aggregated 0.5deg x 0.5deg spatial resolution for the 2003-2016 time period. Please see the FIRECAM Github repository and our paper for more information. The paper describes the methodological differences among these inventories and metrics we developed to diagnose spatial biases and uncertainties. We recommend end-users to use multiple inventories in model runs, if possible. As we show in our paper, the choice of emissions inventory can significantly impact model results. If this is not feasible, please take the time to see how much emissions estimates vary in your study region using the FIRECAM tool.
Previous issues that are now resolved
Fix bug in biomass burning emissions when GFED is turned off
This update was included in v11-02f (approved 17 May 2018).

- I've been learning GEOS-Chem v11-01 and have encountered two anomalies (one a bug, one a potential bug) when I turn off GFED. These also appear to persist in v11-02d.
- The first issue is that the model defaults to using BOND biomass burning if GFED (or FINN) is off. This is a bit strange, especially since BOND biomass burning would then be turned on if a user turned off GFED and FINN but turned on QFED - this would lead to double biomass burning emissions for BC and OC. This can be avoided by defining a separate emission extension for BOND biomass burning in HEMCO_Config.rc, i.e. replacing this:
(((.not.GFED.or.FINN 0 BOND_BM_BCPI $ROOT/BCOC_BOND/v2014-07/Bond_biomass.nc BC 2000/1-12/1/0 C xy kg/m2/s BCPI 70 2 1 0 BOND_BM_BCPO - - - - - - BCPO 71 2 1 0 BOND_BM_OCPI $ROOT/BCOC_BOND/v2014-07/Bond_biomass.nc OC 2000/1-12/1/0 C xy kg/m2/s OCPI 72 2 1 0 BOND_BM_OCPO - - - - - - OCPO 73 2 1 0 BOND_BM_POG1 - - - - - - POG1 74/76 2 1 0 BOND_BM_POG2 - - - - - - POG2 74/77 2 1 ))).not.GFED.or.FINN
- with something like this:
(((BOND_BBURN 0 BOND_BM_BCPI $ROOT/BCOC_BOND/v2014-07/Bond_biomass.nc BC 2000/1-12/1/0 C xy kg/m2/s BCPI 70 2 1 0 BOND_BM_BCPO - - - - - - BCPO 71 2 1 0 BOND_BM_OCPI $ROOT/BCOC_BOND/v2014-07/Bond_biomass.nc OC 2000/1-12/1/0 C xy kg/m2/s OCPI 72 2 1 0 BOND_BM_OCPO - - - - - - OCPO 73 2 1 0 BOND_BM_POG1 - - - - - - POG1 74/76 2 1 0 BOND_BM_POG2 - - - - - - POG2 74/77 2 1 )))BOND_BBURN
- The second issue is that if someone is to use the BOND biomass burning emissions, either intentionally or not, the emissions are not showing up in the BC-BIOB diagnostic. Instead, that diagnostic is all zeros, even though there is still clearly biomass burning emissions occurring in the model. Figures demonstrating this for a one month simulation of the standard code for July 2013, 4x5, GEOSFP, can be found here.
- There is thus a bug in the BC-BIOB diagnostic — has anyone else encountered this or have a suggestion for a fix?

- A question came up recently about v11-01 defaulting to using BOND biomass burning emissions if QFED is switched on and both FINN and GFED are switched off. This can be fairly easily fixed by adding the following code in red:
