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?
