Dear everyone:  
Hello, I want to use CMAQ to do a simulation in October 2024, in bankhead national forest area. But now I cannot emission data for that. Can I use old emission data for that cause I don’t think there will be too much difference in that area. What kind of difficulties I will face or I can find emission data for 2024 from other inventory.
