The AdvFluxVert collection

Here is a sample definition section for the AdvFluxVert collection. This is used to obtain vertical fluxes of species from advection.

  • If this collection is not already present in the HISTORY.rc file in the GEOS-Chem run directory for your selected simulation, you can copy and paste this into your HISTORY.rc file and edit accordingly.
  • To prevent an individual field from being included in the diagnostic output, place a comment character # in front of the field name.
  • Please see our Legend for History diagnostics page for more information about each of the collection tags.
  AdvFluxVert.template:       '%y4%m2%d2_%h2%n2z.nc4',
  AdvFluxVert.format:         'CFIO',
  AdvFluxVert.frequency:      00000100 000000
  AdvFluxVert.duration:       00000100 000000
  AdvFluxVert.mode:           'time-averaged'
  AdvFluxVert.fields:         'AdvFluxVert_O3               ', 'GIGCchem',
::

This table describes the diagnostic quantities belonging to the AdvFluxVert collection:

  • NOTE: You can use this diagnostic to obtain the vertical flux of all species with the ?ADV? wildcard. But in practice, this collection is used to obtain the vertical flux of O3 in advection, which is needed for benchmarking purposes.
Diagnostic name Description Units Wildcards Simulations Notes
AdvFluxVert_<spcname> Vertical flux of species in advection kg/s ?ADV? Can be used with
  • all simulations

Typically only used with

  • benchmark
  • Added in 12.6.0

The Transport collection

The Transport collection contains diagnostics for age of air. This is primarily used for benchmarking purposes

Here is a sample definition section for the Transport collection.

  • If this collection is not already present in the HISTORY.rc file in the GEOS-Chem run directory for your selected simulation, you can copy and paste this into your HISTORY.rc file and edit accordingly.
  • To prevent an individual field from being included in the diagnostic output, place a comment character # in front of the field name.
  • Please see our Legend for History diagnostics page for more information about each of the collection tags.
  Transport.template:         '%y4%m2%d2_%h2%n2z.nc4',
  Transport.format:           'CFIO',
  Transport.frequency:        'End',
  Transport.duration:         'End',
  Transport.mode:             'instantaneous'
  Transport.fields:           'Met_AgeOfAir                  ', 'GIGCchem',
::

This table describes the diagnostic quantities belonging to the Transport collection:

Diagnostic name Description Units Wildcards Simulations Notes
Met_AgeOfAir
  • NOTE: This collection was merged into StateMet in GEOS-Chem 13.0.0 and later versions
Age of air years Can be used with
  • all simulations

Typically only used with

  • benchmark
  • TransportTracers
  • Added in 12.2.0
  • Removed in 12.2.0

PLEASE NOTE: The Age of Air diagnostic will be zero everywhere at the surface level, but nonzero at levels above the surface.
