The ConcAboveSfc collection

The ConcAboveSfc diagnostic collection uses dry deposition quantities (surface resistance, dry deposition velocity) to compute the species concentration of O3 and HNO3 at a given altitude (such as 10 m) above the surface. This will facilitate comparison between GEOS-Chem and observational networks (e.g. CASTNET), which often place instruments above the canopy at approx. 10m height.

Here is a sample definition section for the ConcAboveSfc 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.
  SpeciesConc.template:       '%y4%m2%d2_%h2%n2z.nc4',
  SpeciesConc.format:         'CFIO',
  SpeciesConc.frequency:      00000100 000000
  SpeciesConc.duration:       00000100 000000

  SpeciesConc.fields:         'SpeciesConc_?ADV?             ', 'GIGCchem',

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

Diagnostic name Description Units Wildcards Simulations Notes
SpeciesConcALT1_<spcname> Chemical species concentrations of O3 or HNO3 at a user-specified height (e.g. 10 m) above the surface mol/mol dry air
  • ?DRYALT?
  • aciduptake
  • benchmark
  • complexSOA
  • complexSOA_SVPOA
  • marinePOA
  • standard
  • tagO3
  • tropchem
  • You must specify the desired altitude above the surface (in m) in the input.geos file.
  • If dry deposition is turned off in your simulation, then you must disable this collection, or else your run will stop with an error.

The DryDep collection

The DryDep collection contains diagnostics for the flux and velocity of each species lost to dry-deposition.

Here is a sample definition section for the DryDep 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.
