Hi teachers, Happy New Year in advance! I have two questions I would like to ask you for advice on:
I noticed that chemical mechanism is something like cmaq_cb05_soa while in CMAQ v5.2 the default mechanism is cb05e51_ae6_aq, are they match to each other?
The second question is how to use EDGAR HTAP v3 in SMOKE model v4.7. I’ve run personal case using my own MET files (GRIDDESC,METCRO2D…) and default scripts for EDGAR processing successfully. And I learnt from that I should modify arinv.edgar.lst for HTAP v3 from earlier thread.
However, I am wondering if I need to modify anything else for HTAP v3 or just modify this part.
I’m not sure if the chemical mechanisms are exactly the same – will need to wait on someone more connected to speciation to respond on this.
In addition to modifying the EMISLST to reflect the new HTAPv3 gridded input files, the user will also need the speciation and temporalization profiles that match the HTAPv3 sectors. A zip file containing these is posted here:
I noticed that in the gspro file you provided for EDGAR htapv3, only category 5B (Brake and Tyre Wear) includes allocation factors for CO, NH₃, PMC, and NOₓ. The NOₓ allocation factors are as follows:
NO: 0.9
NO₂: 0.092
HONO: 0.0080
However, I couldn’t find allocation factors for other sources.
Would it be appropriate to apply the same NOₓ allocation factors to other sources, or do you have a more detailed allocation scheme available?
