4. GEOS–Chem Shared Data Directories

4.1 Overview

The GEOS–Chem shared data directories contain the various meteorological data fields, emissions, and other data that GEOS–Chem will read in during the course of a simulation. You must download the shared data directories via FTP or a similar utility (e.g. wget, FireFTP, SecureFX, etc.).

Please see the following sections for more information about the servers from where you may download the GEOS–Chem shared data directories:

  1. Chapter 2.4.1: Data Archives
  2. Chapter 2.4.2: Downloading instructions

Here follows a description of each of the subdirectories of the 1° x 1°, 2° x 2.5°, and 4° x 5° data directories, and the files contained within them.

4.2 The GEOS_NATIVE directories

GEOS–Chem v9–02 can regrid emissions data stored at its native resolution (typically on the GMAO 1° x 1° horizontal grid or generic 1° x 1° grid) to coarser resolution. The subdirectories of GEOS_NATIVE (listed below) contain emissions and other input data at this native resolution.

Assume that all files are in GEOS–Chem binary punch format unless otherwise specified. We have started the process of migrating from binary punch format to COARDS-compliant netCDF.

Please note:


4.2.1 The AEIC_201301 subdirectory

NOTES:

  1. The AEIC emission inventory is now the default inventory for aircraft emissions in GEOS-Chem. The data in aircraft_NOx_200202 is now considered obsolete.

Files Description
AEIC.nc

Contains monthly burned fuel, NOx emissions, total hydrocarbon emissions, and CO emissions placed on the generic 1° x 1° grid. Data is resolved vertically in 60.96 m increments for the first 304.8 m and 205.8m increments thenceforth. The data was generated from the Aircraft Emission Inventory Code (AEIC), based on 2005 scheduling data. Nick Simone prepared the data and Sebastian Eastham converted the files to netCDF format for use in GEOS–Chem.

4.2.2 The anth_scale_factors_201207 subdirectory

NOTES:

  1. This is an update of the now obsolete anth_scale_factors_201111 subdirectory. Scale factors are updated to 2010 over Canada and USA. Global scalars remain constant after 2006..
  2. The anth_scale_factors_200811, anth_scale_factors_200905, and anth_scale_factors_200911 subdirectories are now obsolete.

EMEP_mask.geos.1x1

Updated mask file for EMEP emissions, submitted by G.C.M. Vinken.

Prior to this fix, the mask used by GEOS–Chem corresponded to the emissions in the EMEP_200510 directory. This mismatch caused no ship emissions to be released over a region of the North Atlantic and north of Norway. The updated mask now corresponds with the new border of the EMEP emissions domain and thus fixes the problem.

NOTES:

  1. For GEOS–Chem v9–01–02 and higher versions, GFED2 emissions data in this subdirectory are superseded by GFED3 emissions data in GFED3_201212. The emissions data in this subdirectory are kept for compatability with older model versions.
  2. The GFED2 emissions in this directory are monthly mean biomass emissions.
  3. GEOS–Chem reads the GFED2 C emissions data on the generic 1x1 grid, then converts to equivalent biomass emissions for each species, and then regrids to the current model grid. Therefore, to change GFED2 biomass emissions, all one has to do is to change the emission factors for the various vegetation types.

4.2.18 The GFED2_3hr_200901 subdirectory

NOTES:

  1. For GEOS–Chem v9–01–02 and higher versions, GFED2 emissions data in this subdirectory are superseded by GFED3 emissions data in GFED3_201212. The emissions data in this subdirectory are kept for compatability with older model versions.
  2. These data were generated for a specific research project. We recommend using either the monthly or 8-day data.
  3. The GFED2 emissions in this directory are 3-hourly data. The "3hr" data are obtained from applying a 3hr diurnal variation to the 8-day averages. The "synoptic" data distribute the 8-day average data in their respective 8 days according to the meteorological ISI index, then apply a 3hr diurnal cycle.
  4. As of 04/30/2009, there are only 4 months of data available: June, July, August and September 2004.

  2. The GFED2 emissions in this directory are 8-day averages.
  3. As of 04/30/2009, the GFED2_emission_factors.txt file, the GFED2_emission_factors_73t.txt file and the GFED2_vegmap.generic.1x1 file are the same versions as are found in the GFED2_200601 subdirectory, which contains monthly emissions. At some point we may upgrade to a newer version of the vegetation map file from Prasad Kasibhatla, but that has not been done as of 04/30/2009.
  4. GEOS-Chem reads the GFED2 C emissions data on the generic 1x1 grid, then converts to equivalent biomass emissions for each species, and then regrids to the current model grid. Therefore, to change GFED2 biomass emissions, all one has to do is to change the emission factors for the various vegetation types.

4.2.40 The Streets_200812 subdirectory

NOTES:

  1. The bpch files in this directory were created from 2 separate inventories (original resolution: 0.5° x 0.5° resolution):
  2. Even though Inventory 2 has total VOC, we cannot use this for GEOS-Chem. GEOS-Chem requires VOC's to be speciated into the various hydrocarbons (ACET,ALD2,ALK4,C2H6,C3H8,CH2O,ISOP,MEK,PRPE), so we use Inventory 1.
  3. IMPORTANT: Biofuel emissions are not separated from anthropogenic emissions.

NOTES:

  1. The anthropogenic emissions from the EPA/NEI99 in this directory have been superseded by the data in the EPA_NEI_200708 and EPA_NEI_200806 directories. However, you should consider using the more recent EPA/NEI05 inventory.
  2. The biofuel emissions in this directory are still used by GEOS–Chem.
  3. The newer EPA/NEI05 inventory only contains anthropogenic emissions. GEOS–Chem will therefore use the biofuel emissions data contained in this directory (EPA_NEI_200411) when you select the EPA/NEI05 inventory.

NOTES:

  1. These directories are for the EPA/NEI99 emissions inventory. You should consider using the newer EPA/NEI2005 inventory.
  2. These directories include the same data than GEOS_1x1/EPA_NEI_200708 subdirectory but at resolutions 4° x 5° and 2° x 2.5°.

4.3.15 The EPA_NEI_200806 subdirectory

NOTES:

  1. These directories are for the EPA/NEI99 emissions inventory. You should consider using the newer EPA/NEI2005 inventory.
  2. Mask file in this directory is the same than in GEOS_1x1/EPA_NEI_200806 subdirectory but at resolutions 4° x 5° and 2° x 2.5°.
  3. The data are the same as EPA_NEI_200708, except for NOx (50% decrease over ozone season only from power plant and industry sectors) and CO (decrease of 60%). Base year for the updated NOx and CO is 2004, since they result from model comparison with ICARTT observations.

4.3.16 The fossil_200104 subdirectory

NOTES:

  1. The GEIA/Piccot inventory is the default inventory for the hydrocarbon emissions (EDGAR is used for NOx, CO, SOx).
  2. You should make sure to turn on the regional emissions inventories (e.g. CAC, BRAVO, EMEP, EPA/NEI, Streets, etc.). These will "overwrite" the GEIA/Piccot emissions in the various regions of the world with more up-to-date emissions.

Files Description
gmi.clim.*.geos4.2x25.nc
gmi.clim.*.geos4.4x5.nc

These files contain 3D climatological monthly mean production rates, loss frequencies, and concentrations for each of the species simulated by the GMI "Combo" model. GMI archives the reaction rates for each kinetic and photolysis reaction, which have been stoichiometrically summed for each individual species, and averaged over all years by L. Murray.

In addition to these individual species:

A3O2, ACET, ACTA, ALD2, ALK4, A3O2, B3O2, Br, BrCl, BrO, BrONO2, C2H6, C3H8, CCl4, CF2Br2, CF2ClBr, CF3Br, CFC113, CFC114, CFC115, CH2O, CH3Br, CH3CCl3, CH3Cl, CH4, CO, Cl, Cl2, CL2O2, ClO, ClONO2, EOH, ETP, GCO3, GLYC, GLYX, GP, GPAN, H,H2, H24O2, H2O, H2O2, HAC, HBR, HCFC141b, HCFC142b, HCFC22, HCOOH, HCl, HNO2, HNO3, HNO4, HO2, HOBr, HOCl, IALD, IAO2, IAP, INO2, INPN, ISN1, ISNP, ISOP, KO2, MACR, MAN2, MAO3, MAOP, MAP, MCO3, MEK, MGLY, MO2, MOH, MP, MRO2, MRP, MVK, MVN2, N, N2O, N2O5, NO, NO2, NO3, NOx, O, O1D, O3, OClO, OH, Ox, PAN, PMN, PO2, PP, PPN, PRN1, PRPE, PRPN, R4N1, R4N2, R4O2, R4P, RA3P, RB3P, RCHO, RCOOH, RIO1, RIO2, RIP, ROH, RP, VRO2, VRP.

we have determined production rates and loss frequencies for:

  1. The NOx family = N + NO + NO2 + NO3 + HNO2
  2. The Ox family = O + O1D + O3

Ox was determined for completeness; we recommend that you use GEOS–Chem with the Linoz (recommended) or Synoz options for stratospheric O3.

NOTES:

  1. The GMI "Combo" model uses a different vertical resolution for GEOS–4 meteorology than does GEOS–Chem. We have regridded these files to the GEOS–4 native vertical grid (55 layers) used by GEOS–Chem.

  2. We created these files from the archived GMI "Combo" monthly mean output (2004–2007) located at:
    ftp://dirac.gsfc.nasa.gov/pub/gmidata2/users/mrdamon/Aura4-Final

gmi.clim.*.geos5.2x25.nc
gmi.clim.*.geos5.4x5.nc

These files contain 3D climatological monthly mean production rates, loss frequencies, and concentrations for each of the species simulated by the GMI "Combo" model. GMI archives the reaction rates for each kinetic and photolysis reaction, which have been stoichiometrically summed for each individual species, and averaged over all years by L. Murray.

The data in these files are placed on the GEOS–5 native vertical grid (72 layers) used by GEOS–Chem. GEOS–Chem will read these data files when being driven by MERRA or GEOS–FP meteorology.

See the above row in this table for a list of included species.

NOTES:

  1. We created these files from the archived GMI "Combo" monthly mean output (2004–2010) located at:
    ftp://dirac.gsfc.nasa.gov/pub/gmidata2/users/steenrod/MERRA

gmi.clim.*.merra.2x25.nc
gmi.clim.*.merra.4x5.nc

Symbolic links to the gmi.clim.*.geos5.2x25 and gmi.clim.*.geos5.4x5 files.

The MERRA vertical grid is the same as the GEOS–5 native vertical grid (72 layers). We need to add the symbolic links so that GEOS–Chem will find these files when being driven by the MERRA meteorology.

EMEP_200806
  • These data are now obsolete.
  • There is a reference to this directory in the code to run the European nested-grid simulation. However, Harvard does not store the data for this simulation. For more information, please refer to the Regional Air Quality Working Group wiki page.
EPA_NEI_200406
  • Replaced by EPA_NEI_200411 and later directories
