Hi,

I am trying to use scripts in smoke\_2019\_platform\_core\_17mar2023 from NEI2019. There is no fertilizer script and its speciation files because CMAQ has bidirectional flux option, but other model may not consider that. Is that possible to provide the speciation files and script for fertilizer sector in NEI2019? or may use the speciation files in old version of NEI2019?  
And no merge script for total onroad, only for diesel and gas.

Thanks in advance.

We recently posted fertilizer files and instructions on how to alter the livestock script to run fertilizer emissions:

Let us know if you still have issues after reviewing and trying these instructions.

Thank you for this information! I will try that later.
