      RCP26_ships_YYYY.2x25.bpch            

RCP45/RCP45_aircraft_YYYY.2x25.bpch        : Emissions for the RCP4.5 scenario
      RCP45_anthropogenic_YYYY.2x25.bpch     from biomass burning, aircraft,

      RCP60_ships_YYYY.2x25.bpch

RCP85/RCP85_aircraft_YYYY.2x25.bpch        : Emissions for the RCP8.5 scenario
      RCP85_anthropogenic_YYYY.2x25.bpch     from biomass burning, aircraft,

Data files were prepared by Chris Holmes (cdholmes@uci.edu).

Addendum (04 Feb 2015):
------------------------
NOTE: We have added the files

  RCP26/RCP26_anthropogenic_YYYY.2x25.OCfix.bpch
        RCP26_ships_YYYY.2x25.OCfix.bpch  

  RCP45/RCP45_anthropogenic_YYYY.2x25.OCfix.bpch
        RCP45_ships_YYYY.2x25.OCfix.bpch  

  RCP85/RCP85_anthropogenic_YYYY.2x25.OCfix.bpch
        RCP85_ships_YYYY.2x25.OCfix.bpch  

which include a fix for inconsistent molecular weights of OC. The original
IPCC RCP emission files for RCPs 2.6, 4.5, and 8.5 use a molecular weight of
106.8 g/mol, while RCP 6.0 uses a molecular weight of 12 g/mol. Evan Couzo
has provided new 2x2.5 emission files for GEOS-Chem with the OC emission rate
adjusted by 106.8/12 for RCPs 2.6, 4.5, and 8.5.
