Hi Mr.Alison,

I am wondering that if your files provided here are for offline gridded transfer or used as input files in smoke model? I read  
a guide file from the earlier thread and I post a part of  
it here. My question is are they different ways to tackle EDGAR database and which one I should consider?

> 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.
