Description
The aerosol simulation is an offline simulation for aerosol tracers only. It uses archived monthly mean OH, NO3, O3 and total nitrate concentrations archived from a previous full-chemistry simulation (more on that below), as well as production and loss rates for H2O2. This simulation does not provide "tagged" capabilities, but reduces the suite of tracers from full chemistry.
NOTES:
- The aerosol-only simuation is currently functional in GEOS-Chem Classic.
- There is currently no aerosol-only run directory for GCHP. Interested users are encouraged to make this modification on their own.
- OH concentrations are archived from the most recent 10-year benchmark simulation.
- O3, NO3 and total nitrate (HNO3+NIT) concentrations, as well as production rates and photolysis rates for H2O2 are archived from the most recent 10-year benchmark simulation.

Practicalities
As with all other Offline chemistry simulations, the GEOS-Chem user community shall be responsible for the scientific content and validation of the aerosol-only simulation.
The SOA simulation was updated in GEOS-Chem v9-02o to include a better tracer lumping scheme, as shown in Figure 1 of Pye et al. 2010.
The offline aerosol is simulation type 10. For a full set of aerosol tracers (based on the 100-tracer full-chemistry SOA simulation), the input.geos should look like this:
Type of simulation : 10 Number of Tracers : 47 Tracer Entries -------> : TR# Name g/mole Tracer Members; () = emitted Tracer #1 : 1 DMS 62.00 Tracer #2 : 2 SO2 64.00 Tracer #3 : 3 SO4 96.00 Tracer #4 : 4 SO4s 96.00 Tracer #5 : 5 MSA 96.00 Tracer #6 : 6 NH3 17.00 Tracer #7 : 7 NH4 18.00 Tracer #8 : 8 NIT 62.00 Tracer #9 : 9 NITs 62.00 Tracer #10 : 10 H2O2 34.00 Tracer #11 : 11 BCPI 12.00 Tracer #12 : 12 OCPI 12.00 Tracer #13 : 13 BCPO 12.00 Tracer #14 : 14 OCPO 12.00 Tracer #15 : 15 DST1 29.00 Tracer #16 : 16 DST2 29.00 Tracer #17 : 17 DST3 29.00 Tracer #18 : 18 DST4 29.00 Tracer #19 : 19 SALA 36.00 Tracer #20 : 20 SALC 36.00 Tracer #21 : 21 MTPA 136.23 Tracer #22 : 22 LIMO 136.23 Tracer #23 : 23 MTPO 136.23 Tracer #24 : 24 TSOG1 150.00 Tracer #25 : 25 TSOG2 150.00 Tracer #26 : 26 TSOG3 150.00 Tracer #27 : 27 TSOG0 150.00 Tracer #28 : 28 TSOA1 150.00 Tracer #29 : 29 TSOA2 150.00 Tracer #30 : 30 TSOA3 150.00 Tracer #31 : 31 TSOA0 150.00 Tracer #32 : 32 ISOG1 150.00 Tracer #33 : 33 ISOG2 150.00 Tracer #34 : 34 ISOG3 150.00 Tracer #34 : 35 ISOA1 150.00 Tracer #36 : 36 ISOA2 150.00 Tracer #37 : 37 ISOA3 150.00 Tracer #38 : 38 BENZ 12.00 (6C) Tracer #39 : 39 TOLU 12.00 (7C) Tracer #40 : 40 XYLE 12.00 (8C) Tracer #41 : 41 ASOG1 150.00 Tracer #42 : 42 ASOG2 150.00 Tracer #43 : 43 ASOG3 150.00 Tracer #44 : 44 ASOAN 150.00 Tracer #45 : 45 ASOA1 150.00 Tracer #46 : 46 ASOA2 150.00 Tracer #47 : 47 ASOA3 150.00
This list can be reduced by turning off any aerosol species (eg. SOA, dust, SS, etc). You may also run without the secondary organic aerosols (MTPA, LIMO, MTPO, TSOG0–3, TSOA0–3, ISOG1–3, ISOA1–3, ASOG1–3, ASOA1–3, ASOAN) if you wish (but we recommend that you use them).
