I need to compare results between CMAQv5.2 and CMAQv5.3.3
so I want to use Mechnism cb6r3_ae6nvPOA_aq in CMAQv5.2 because my Emission speciation from other’s was made of cb6r3_ae6nvPOA_aq .
I tried to find cb6r3_ae6nvPOA_aq in CMAQ but there is no same Mechanism in CMAQv5.3.3
Is it possible to add CMAQv5.2 Mechanism to CMAQ v5.3.3
or any same mechanism in CMAQ but I do not think there is.
Hello,
If you want to run an ‘nv’ version of cb6r3_ae6 in CMAQv5.3.3, use the Emission Control File to put all of the organic aerosol emissions to APOC and APNCOM (set their scale factors each to 1.0). Then make sure to delete or comment all emission rules for the semivolatile organics, or set their scale factors to 0.0.
Cheers,
Ben Murphy
How can I use Emission Control file and where is it?
Can you give me an example, specifically??
Sure,
For general information, here’s a paper we published: GMD - The Detailed Emissions Scaling, Isolation, and Diagnostic (DESID) module in the Community Multiscale Air Quality (CMAQ) modeling system version 5.3.2
For more specific tutorials, you may view the CMAQ user guide here:
CMAQ/CMAQ_UG_appendixB_emissions_control.md at main · USEPA/CMAQ · GitHub
Cheers,
Ben
Am I following well?
