Hi!
I want to define gspro_combo profiles for some sources with different SCCs. How can I do that?
There are examples of using gspro_combo in the EPA distributions – check the speciation zip file here:
https://gaftp.epa.gov/Air/emismod/2016/v2/ancillary_data/
GSPRO_COMBO is used for Canada and Mexico.
In the U.S. instead of GSPRO_COMBO we use the extended form of the GSREF format for the oil and gas sector, for example.
https://cmascenter.org/smoke/documentation/4.8.1/html/ch08s05s05.html
shows that there is a speciation profile split factor in column M.
