Hi,

I intend to prepare CMAQ-ready emissions for the 36US1 domain. I have one concern. How can I define the WPS geogrid options or MCIP run script in a way that the met output domain matches the 36US1 domain grid description (To have the same domain for the WRF-SMOKE-CMAQ platform). I know about the map projection, but I don’t know how to set the _ref\_lat_ and _ref\_lon_ values or X0 and Y0 in MCIP run script. Actually, I need a general answer to this question, and 36US1 is an example.

Thanks,  
Ali
