This benchmark simulation is GEOS-Chem v11-01f-merra2-RnPbBe-TURBDAY. The
following updates since GEOS-Chem v11-01d-RnPbBe have been applied:

    VERSION | FEATURES INCLUDED                           | APPROVAL DATE
   =======================================================================
    v11-01e   - Update HEMCO from version 1.1.005 to        04 Jan 2016
                version 1.1.016
              - Speed up GEOS-FP and MERRA-2 met field
                input by only opening each netCDF file
                once per day
              - Bug fixes for Arctic Hg updates in v11-01c
              - Bug fix to update air quantities after
                specific humidity is updated in non-local
                PBL mixing
              - Tracer Units Phase 1: Initial
                implementation of area-independent tracer
                units
              - Modifications for running nested grid
                simulations with MERRA-2
              - Species Database Phase 2a:
                * Remove inconsistencies in the
                  definitions of physical properties of
                  GEOS-Chem species;
                * Use proper molecular weights for sea
                  salt aerosols in the dry deposition
                  module;
                * Give SO4s and NITs the same molecular
                  weight as SALC;
                * Define molecular weight fields of the
                  Input_Opt object from the species
                  database
              - Species Database Phase 2b:
                * Update the wetdep module to use the same
                  Henry's law functions as are used in
                  HEMCO, for consistency's sake

    v11-01f   - Bug fixes for hydrophobic aerosol           TBD
                properties
              - Use an updated EMEP mask file to prevent
                zero emissions at 30 N for 2° x 2.5° or
                higher resolutions
              - Correct too-high emissions of Hg2 over
                China and EU
              - Fix typo in HEMCO extension module
                hcox_gc_RnPbBe_mod.F90
              - Fix syntax error in globchem.dat for the
                MOBA + OH -> MOBAOO reaction rate
              - Fix bug in reaction ISNOOA + NO2 -> PMN
                in globchem.dat
              - Fix an emissions error in the SOA-SVPOA
                simulation
              - Add a script (NcdfUtil/perl/isCoards) to
                determine if a netCDF file is COARDS-
                compliant
              - Consistent physical parameter values
                throughout GEOS-Chem
              - Add optimal timestep settings to the
                standard GEOS-Chem run directories (via
                the GEOS-Chem Unit Tester)
              - Drive full-chemistry simulations with
                MERRA-2 met fields
              - NetCDF Output Phase 1:
                * Input and output restart file in netCDF
                  format for all simulations except mercury 
              - Add further fixes for compiling GEOS-Chem
                with PGI Fortran


This simulation utilized GEOS-FP met fields for the year 2013, with a 4-year
spinup repeating 2013 meteorology. The full PBL mixing scheme (TURBDAY) was
used.
