FINNv1 biomass burning emissions

Overview of FINN v1 data

NOTE: At present, the FINN biomass emissions inventory has been added to the non-standard SEAC4RS research version of GEOS-Chem. FINN is also available for simulations with GEOS-Chem v10-01 and higher versions via the HEMCO emissions component. While the standard GEOS-Chem simulation uses GFED4 biomass burning emissions, you may select FINN instead of GFED4 if your research requires it.

"The Fire INventory from NCAR version 1.0 (FINNv1) provides daily, 1-km resolution, global estimates of the trace gas and particle emissions from open burning of biomass, which includes wildfire, agricultural fires, and pre- scribed burning and does not include biofuel use and trash burning" (Wiedinmyer et al., 2011). For more information about this inventory, see:
Wiedinmyer, C., S. K. Akagi, R .J. Yokelson, L. K. Emmons, J. A. Al-Saadi, J. J. Orlando, and A. J. Soja. The Fire INventory from NCAR (FINN): a high resolution global model to estimate the emissions from open burning. Geosci. Model Dev., 4, 625–641, 2011. [1]

Current non-standard implementations

As of IGC6 (May 2013), FINNv1 has been implemented in non-standard versions of GEOS-Chem by at least 3 groups. These implementations allow users to use the ASCII emissions files (or a converted gridded netcdf equivalent) available directly from http://bai.acd.ucar.edu/Data/fire/. If you are interested in working with FINNv1 emissions immediately, please contact Jingqiu Mao (Jingqiu.Mao@noaa.gov), Min Huang (Min.Huang@jpl.nasa.gov), or Jenny Fisher (jennyf@uow.edu.au).

Previous issues that are now resolved

Minor fixes for FINNv1

NOTE: The following issue was resolved during the public comment period for GEOS-Chem v10-01.

Luke Schiferl (MIT) noted that the entries for FINNv1 biomass burning in the HEMCO configuration files that ship with the GEOS-Chem Unit Tester were not consistent with the most recent FINNv1 data. We have therefore edited the HEMCO configuration files accordingly with the proper entries:

We also fixed a bug in HEMCO that was causing the default FINN biomass diagnostics to be zeroed out.

Bug fixes in FINN indexing

NOTE: The following issue will be resolved in GEOS-Chem v11-01.

Several users reported problems using the HEMCO extension for FINN biomass burning emissions in GEOS-Chem v10-01. When users turn on the FINN extension with bounds checking turned on, GEOS-Chem returns the error:

  forrtl: severe (408): fort: (2): Subscript #1 of the array SPCNAMES has value 21 which is greater than the upper bound of 18

The FINN indexing can get messed up. Jenny Fisher and I have updated the FINN module and this update should fix the problem. This fix is included in HEMCO v2.0.

From what I can tell the FINN bug primarily impacted carbon aerosol emissions while it looks like other species emissions are fine.

Attached is the updated FINN module. It replaces the original hcox_finn_mod.F90 module in /HEMCO/Extensions. This module has been tested with HEMCO v1.1.016 and higher but not yet within the v10-01 public release code of GEOS-Chem.

This version also requires an update to your HEMCO_Config.rc: the scale factors need to be specified as Scaling_CO instead of CO scale factor:

114     FINN              : off   NO/CO/ALK4/ACET/MEK/ALD2/PRPE/C3H8/CH2O/C2H6/SO2/NH3/BCPI/BCPO/OCPI/OCPO/GLYC/HAC
    --> FINN_daily        :       false
    --> Scaling_CO        :       1.0

NOTE: This fix will only work with GEOS-Chem v11-01e and later versions because GEOS-Chem was updated to HEMCO v1.1.016 in that version.
