== Implementation in GEOS-Chem ==
'''Jenny Fisher''' (U. Wollongong), '''Jingqiu Mao''' (Princeton), and '''Christine Wiedinmyer''' (NCAR) have worked to implement FINNv1 into the standard version of GEOS-Chem. This implementation includes a number of features, many of which are improvements over the non-standard implementations currently used (see below):
#Improved speciation for GEOS-Chem, including specialty simulations like SOA
#Compatibility with new emissions module (including use of netcdf, high-resolution inputs, online regridding, etc.)
#GFED-like online computation of emissions for most species based on emissions of a single species for each land type (significantly reducing file storage requirements)
#Ability to use daily or monthly emissions
If you have questions or suggestions, please contact Jenny Fisher (jennyf at uow dot edu dot au) and Jingqiu Mao (jmao at princeton dot edu) --[[User:Bmy|Bob Y.]] 14:47, 5 March 2015 (EST)

=== UPDATE (July 2014) ===
A new version of FINNv1 emissions has been implemented [[GEOS-Chem v10-01]] via the [[HEMCO|HEMCO emissions component]]. The new implementation starts from CO2 emissions (gridded to high resolution from original FINN files) for 6 different land types. CO2 emissions are converted to emissions of other gas phase and aerosol species using emission ratios provided by Christine Wiedinmyer. Emissions of non-methane organic compounds are derived from a single NMOC species (also computed from ratios to CO2) using speciation factors (also provided by Christine Wiedinmyer). These calculations are performed online in GEOS-Chem, then summed over land types and regridded to model resolution. FINN can be used with daily or monthly resolution, and emissions will be available with a lag of approximately 6 months behind real time (in special cases, near-real-time emissions can also be provided).
This implementation includes support for many species, including those used in specialised GEOS-Chem simulations. Some of these species are not currently emitted in publicly available releases of GEOS-Chem, and interested users will be responsible for adding relevant emissions-related code (i.e. defining IDBs, etc.). No changes to the FINN code itself should be necessary to use these species. The current list of FINN species includes:
#Species currently emitted by biomass burning in standard versions for full chemistry and/or specialty simulations ''(no code changes necessary)'': CO2, CO, CH4, NO, SO2, OC, BC, NH3, ACET, ALD2, ALK4, BENZ, C2H2, C2H4, C2H6, C3H8, CH2BR2, CH2O, CH3BR, GLYC, GLYX, HAC, MEK, MGLY, PRPE, TOLU, XYLE
#Species either not currently emitted or emitted but not by biomass burning in standard versions ''(code changes necessary)'': ACTA, CH3CN, CH3I, DMS, EOH, HCN, HCOOH, HNO2, ISOP, MACR, MNO3, MOH, MVK, R4N2, RCHO, LIMO, MTPA, MTPO
#Species currently lumped online in the FINN code: ETBENZ (with TOLU), STYR (with TOLU), TMB (with XYLE), APINE (with MTPA), BPINE (with MTPA), CARENE (with MTPA)
#Species/groupings that don't currently exist but that are defined in FINN inputs for possible implementation by interested users: AROM, FUR, ROH, RCOOH, SESQ
For the original lumping of VOCs into GEOS-Chem species, see [http://wiki.seas.harvard.edu/geos-chem/images/FINN_final_lumping.pdf FINN_final_lumping.pdf]
Potential future updates include more detailed treatment of terpenes and of secondary species like PAN. If you have an interest in working on emissions of these species, please contact me (jennyf@uow.edu.au) and/or Christine (christin@ucar.edu).

=== FINN as a HEMCO extension ===
In [[GEOS-Chem v10-01]] and newer versions, the FINN biomass burning emissions are computed via the [[HEMCO|HEMCO emissions component]].  We have created [http://ftp.as.harvard.edu/gcgrid/data/ExtData/HEMCO/FINN/v2015-02/README new data files] (in [[Preparing data files for use with HEMCO|COARDS-compliant netCDF format]]) for use with HEMCO.  These new data files are contained in the [[HEMCO data directories|HEMCO data directory tree]].  For detailed instructions on how to download these data files to your disk server, please see our [[HEMCO_data_directories#Downloading_the_HEMCO_data_directories|''Downloading the HEMCO data directories'' wiki post]].

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]

FINN v1.6 data

FINN v1.5 data

FINN v1.1 data

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.
