Implementation via HEMCO

MIX emissions are read into GEOS-Chem via the HEMCO emissions component. The sections below describe various aspects of how to specify MIX in your configuration files.

Available years

Which year of inventory is GEOS-Chem using? 2008 or 2010?

In the configuration file HEMCO_Config.rc file, the MIX entries are:

    0 MIX_NO_IND   $ROOT/MIX/v2015-03/MIX_Asia_NO.generic.025x025.nc   NO_INDUSTRY      2008-2010/1-12/1/0 C xy kg/m2/s  NO   1/27/25/1006  1/2 45
    ...
    0 MIX_CO_IND   $ROOT/MIX/v2015-03/MIX_Asia_CO.generic.025x025.nc   CO_INDUSTRY      2008-2010/1-12/1/0 C xy kg/m2/s  CO   6/28/26/1006  1/2 45
    ...
    0 MIX_SO2_IND  $ROOT/MIX/v2015-03/MIX_Asia_SO2.generic.025x025.nc  SO2_INDUSTRY     2008-2010/1-12/1/0 C xy kg/m2/s  SO2  11/29/1006    1/2 45

The C setting means that GEOS-Chem will use the closest available date to 2008-2010/1-12/1/0. If the simulation year is prior to 2008, HEMCO will use 2008 emissions scaled to the simulation year. If the simulation year is after 2010 HEMCO will use 2010 emissions.
