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/](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. > **[Hemispheric Modeling Support in SMOKE Modeling System](https://docs.google.com/document/d/1veqEjaTPbDpkqHAIcyReokvv6MaENz0TrwOcFl1ewac/edit#heading=h.xo1iz1nkhapd)** > > Hemispheric Modeling Support in SMOKE Modeling System Developed by: Bok H.

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