The CH4 collection
The CH4 collection contains diagnostics for loss of CH4 and OH concentration for the CH4 specialty simulation.
Here is a sample definition section for the CH4 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.
CH4.template: '%y4%m2%d2_%h2%n2z.nc4', CH4.format: 'CFIO', CH4.frequency: 00000100 000000 CH4.duration: 00000100 000000 CH4.mode: 'time-averaged' CH4.fields: 'OHconcAfterChem ', 'GIGCchem', 'LossCH4byClinTrop ', 'GIGCchem', 'LossCH4byOHinTrop ', 'GIGCchem', 'LossCH4inStrat ', 'GIGCchem', ::
This table describes the diagnostic quantities belonging to the CH4 collection:
|Diagnostic name||Description||Units||Wildcards||Simulations||Notes||Bpch equiv.|
|LossCH4byClinTrop||Loss of CH4 by reaction with Cl in the troposphere||kg/s||
|LossCH4byOHinTrop||Loss of CH4 by reaction with OH in the troposphere||kg/s||
|LossCH4inStrat||Loss of CH4 in the stratosphere||kg/s||
|OHconcAfterChem||OH concentration after chemistry||kg/s|
