The BoundaryConditions collection
NOTE: If you are not setting up for a nested-grid simulation, then you can disable this collection.
The BoundaryConditions diagnostic collection contains advected species concentrations (archived from a global simulation) that will be used by nested-grid simulations as transport boundary conditions. Like SpeciesConc, it archives data with units of mol/mol dry air.
Here is a sample definition section for the SpeciesConc 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.

The Restart collection
The Restart diagnostic collection contains fields for saving out to the GEOS-Chem restart file. This type of diagnostic output is used in all GEOS-Chem simulations; therefore, we have listed Restart first in the HISTORY.rc files that ship with each GEOS-Chem run directory.
Here is a sample definition section for the Restart 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.
NOTE: The restart file will be created in the GEOS_Chem run directory, not in the OutputDir sub-folder.

The SpeciesConc collection
The SpeciesConc diagnostic collection contains advected species concentrations. This type of diagnostic output is used in all GEOS-Chem simulations.
Here is a sample definition section for the SpeciesConc 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.
