Overview
In GEOS-Chem v10-01 and later versions, emissions are read, regridded, and calculated by the HEMCO emissions component. The emission settings are specified in the HEMCO Configuration file (HEMCO_Config.rc).
For more information about the HEMCO_Config.rc file, please see:

Enabling and disabling emissions
The HEMCO_Config.rc file for each GEOS-Chem simulation contains a set of switches that allow you to quickly toggle individual emissions inventories on or off.
Each time you create a GEOS-Chem run directory from the Unit Tester, a new HEMCO_Config.rc file with default emissions settings will be created in the run directory. These default settings are located near the top of the HEMCO_Config.rc file.
For example, the default emissions settings for the "Standard" full-chemistry simulation are:
# ExtNr ExtName on/off Species 0 Base : on * --> HEMCO_RESTART : true --> AEIC : true --> BIOFUEL : true --> BOND : true --> BRAVO : true --> CAC : true --> XIAO : true --> EDGAR : true --> HTAP : false --> EMEP : true --> EMEP_SHIP : true --> GEIA : true --> LIANG_BROMOCARB : true --> NEI2005 : false --> NEI2011 : true --> RETRO : true --> SHIP : true --> NEI2011_SHIP : false --> MIX : true --> STREETS : false --> VOLCANO : true --> RCP_3PD : false --> RCP_45 : false --> RCP_60 : false --> RCP_85 : false --> QFED2 : false # ----------------------------------------------------------------------------- 100 Custom : off - 101 SeaFlux : on DMS/ACET 102 ParaNOx : on NO/NO2/O3/HNO3 --> LUT data format : nc --> LUT source dir : $ROOT/PARANOX/v2015-02 103 LightNOx : on NO --> OTD-LIS factors : true --> CDF table : $ROOT/LIGHTNOX/v2014-07/light_dist.ott2010.dat 104 SoilNOx : on NO --> Use fertilizer NOx: true 105 DustDead : on DST1/DST2/DST3/DST4 106 DustGinoux : off DST1/DST2/DST3/DST4 115 DustAlk : off DSTAL1/DSTAL2/DSTAL3/DSTAL4 107 SeaSalt : on SALA/SALC/Br2 --> SALA lower radius : 0.01 --> SALA upper radius : 0.5 --> SALC lower radius : 0.5 --> SALC upper radius : 8.0 --> Emit Br2 : true --> Br2 scaling : 1.0 116 MarinePOA : off MOPO/MOPI 108 MEGAN : on ISOP/ACET/PRPE/C2H4/ALD2 --> Isoprene scaling : 1.0 --> CO2 inhibition : true --> CO2 conc (ppmv) : 390.0 109 MEGAN_Mono : on CO/OCPI/MONX 110 MEGAN_SOA : on MTPA/MTPO/LIMO/SESQ 111 GFED : on NO/CO/ALK4/ACET/MEK/ALD2/PRPE/C3H8/CH2O/C2H6/SO2/NH3/BCPO/BCPI/OCPO/OCPI/POG1/POG2/NAP --> GFED3 : false --> GFED4 : true --> GFED_daily : false --> GFED_3hourly : false --> Scaling_CO : 1.05 --> Scaling_POG1 : 1.27 --> Scaling_POG2 : 1.27 --> Scaling_NAP : 2.75e-4 --> hydrophilic BC : 0.2 --> hydrophilic OC : 0.5 --> fraction POG1 : 0.49 114 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 --> hydrophilic BC : 0.2 --> hydrophilic OC : 0.5
If you would like to turn off NEI2011, simply change the true in this line:
--> NEI2011 : true
to false:
--> NEI2011 : false
And if you also wanted to turn off the MEGAN biogenic emissions, simply change the on in this line:
108 MEGAN : on ISOP/ACET/PRPE/C2H4/ALD2
to off:
108 MEGAN : off ISOP/ACET/PRPE/C2H4/ALD2
etc.
