About adjoint forcing file (CMAQv5.0-adjoint model)

Hello,
I am researching on a study related to inverse modeling using cmaq adjoint model(v5.0, https://gmd.copernicus.org/articles/13/2925/2020/gmd-13-2925-2020.pdf).

So, I downloaded a source code at Zenodo website([CMAQ 5.0 Adjoint | Zenodo]).

I compiled the adjoint models code.

Then I tried to execute backward model, but it did not work because that is not exist about adjoint forcing file.

Q) How can i define adjoint forcing file?

Best regards,

I have encountered the same problem. Do you know how to make forcing files now?
