The MICM suite contains CCPP-compliant schemes.  

The schemes are selected by a user, depending on the exact configuration of the chemistry suite.

MICM schemes:

• mass_quantities_util

  • Computes the Mass Density.  

  • This is marked for obsolescence when the host model (or suite interstitials) are able to support this utility function of the atmospheric state.

• k_rateConst

  • Computes the rate constants for each of the kinetic reactions.  

  • Includes FORTRAN snippets generated from the Configurator as specified in the /generated/ directory
    • k_rateConst.inc
    • rate_functions.inc

• tuv_photolysis

  • Computes the rate constants for the all cross section and quantum yields stored in TUV.

• photolysis_interstitial

  • Computes the rate constants for each photodecomposition in a mechanism tag.  Uses the photolysis packages available.

  • Includes FORTRAN snippets generated from the Configurator as specified in the /generated/ directory
    • prates.inc

• chemistry_driver_moz, or chemistry_driver_ros

  • Computes rates for each reaction

  • Computes forcing for each molecule

  • Includes FORTRAN snippets generated from the Configurator as specified in the /generated/ directory
    
    • forcing.inc
    • rates.inc
    • jacobian.inc

  • Advances the volume mixing ratio of all species, given the ODE system describing the kinetics of a mechanism tag
