Revision as of 19:15, 2 January 2019

This page describes the options for biomass burning emissions in GEOS-Chem.

NOTE: In GEOS-Chem v10-01 and higher versions, biomass burning emissions are handled by the HEMCO emissions component.

GFED4

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.

FINNv1

The FINNv1 biomass burning emission inventory has been added to GEOS-Chem v10-01 via the HEMCO emissions component. This inventory may be used to replace GFED4 for research purposes.

--Melissa Sulprizio 10:21, 18 February 2015 (EST)

QFED

The QFED biomass burning emission inventory has been added to GEOS-Chem v10-01 via the HEMCO emissions component. This inventory may be used to replace GFED4 for research purposes.

--Melissa Sulprizio (talk) 18:27, 14 September 2016 (UTC)

GFAS

The GFAS biomass burning emission inventory will be added to GEOS-Chem 12 via the HEMOC emissions component. This inventory may be used to replace GFED4 for research purposes.

--Melissa Sulprizio (talk) 12:19, 4 October 2018 (UTC)

FLAMBE

The FLAMBE biomass burning emissions inventory was used in several research versions of GEOS-Chem, especially to provide modeling support for aircraft field campaigns. But it was never adopted as a standard GEOS-Chem biomass burning emissions option.

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:

with something like this:

  )))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:
