This benchmark simulation is GEOS-Chem v11-02e-Run0. The following
updates since GEOS-Chem v11-02d-Run2 have been applied:

    VERSION        | FEATURES INCLUDED
   =======================================================================
    v11-02d          Features impacting the full-chemistry simulation:
                     - Monthly mean surface methane distributions
                     - UCX updates, including:
                       * Remove initial stratospheric 2D mixing ratio option
                       * UCX stratospheric water boundary condition update
                       * Remove UCX=y as compile switch and use Input_Opt%LUCX
                         instead
                     - Use monthly mean stratospheric prod/loss rates from UCX
                       simulation for all species
                     - Metal catalyzed oxidation of SO2 as a switch (default:on)
                     - Add SOA updates and bug fixes, including:
                       * Remove MONX from chemical mechanisms
                       * Add MTPO as a species in full-chemistry simulations
                       * Updating SOAP and SOAS entries in HEMCO to follow
                         MTPA+LIMO+MTPO rather than MONX
                       * Use simple SOA in calculation of PM2.5, AOD, and
                         aerosol mass by default
                       * Always use SOA formation from aqueous isoprene uptake
                         (remove switch from input.geos)
                       * Fixes for isoprene SOA for consistency with Marais et
                         al. (2016)
                     - Fix dust rainout settings to match BCPO
                     - Fixes in gckpp_HetRates.F90 for halogen chemistry
                     - Add bug fix in sulfate_mod.F involving reorder IF
                       statements for Fahey and Seinfeld decision algorithm
                     - Sync GEOS-FP files on Harvard ftp with files at Dalhousie

                     Features NOT impacting the full-chemistry simulation:
                     - Spatially varying OM/OC as a switch (off by default)
                     - Update Rn-Pb-Be-Pasv simulations to use 72 levels by
                       default
                     - Bug fixes for ISORROPIA II stable mode
                     - Change input.geos timestep units from minutes to seconds
                     - Fixes for ND21 binary diagnostics
                     - Fix bug in HEMCO reference time code
 
This benchmark simulation uses the standard chemistry mechanism (i.e. tropchem
+ UCX + SOA + halogens ) and 72 vertical levels.
