Hello to everyone.
I want to run WRF and CMAQ with Global emission like GEIA .I have created the WRF output. and I have completely installed the CMAQ and I can run the CMAQ 2016 test case without any bugs.
But I don’t have any idea about how prepare the global emission as input for CMAQ.in other word after downloading the Global emission from GEIA (http://www.geiacenter.org/) what should I do ?
Please describe with details for me.I really am beginner in CMAQ and your points will be very useful for me.
Thanks a lot
This is really a great question without a super simple answer. Global emissions are typically lat/lon and generally speciated (NOx, SO2, NH3, NMVOC, BC, OC), while CMAQ is usually run lambert conformal with very specific speciation (NO, NO2, SO2, carbon bond 6 vocs, and ae7 aerosols).
For anthropogenic emissions, the EPA/OAQPS/AQAD/EIAG group does have an EDGAR-HTAP processor built in to SMOKE, but it is oriented toward a very specific dataset (with some post processing). It takes global data and makes CMAQ-ready data. @bbaek or @eyth.alison can provide more details.
GEIA (really ECCAD) does have inventories for other sectors (biogenic, volcanos, soil NOx, fires) and for other sources of anthropogenics. I am not aware of comparable processors for other sectors or sources.
I think it would be good to have

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.

Thanks a lot for your points.
It is great.
Thanks for your attentions
It will be very useful.
