How to combine EDGAR with CMAQ

[yan2024]

Hi guys, I am wondering if anyone followed this guide provided by Mr.bbaek and combined EDGAR with CMAQ in SMOKE programs successfully?I would like to learn the suggestions from you and I wanna know if I can apply the ncf file provided directly for following grids allocation?(GEOCODE_EDGAR0.ncf - Google Drive)

Thank you all for the support all the time and wishing you peace, joy and happiness through Christmas and the coming year！

Run CMAQ with Golobal emission dataset (GEIA)

As of SMOKE v4.5, SMOKE can process the EDGAR global inventory to generate CMAQ-ready chemically spectated gridded hourly emissions with some limitations. Because EDGAR inventories are pre-gridded, we can only apply a single speciation profile and a single set of temporal (monthly, weekly and diurnal) profiles by each EDGAR sector. Here is the detail information on how to process EDGAR global emission inventory files through SMOKE.

@yan2024 This feature in SMOKE has been actively used in the U.S. EPA hemispheric modeling applications. So, yes, you can use this feature to process Lat/Lon projection sectoral EDGAR or HTAP gridded emissions via SMOKE. You can define your modeling domain using IOAPI_GRIDNAME_1 variable for Grdmat to regrid the original 0.1 degree grid into your domain.

Thank you so much！Have a nice day！
