Hi @CN_CODER, I am realizing that we had sort of the same error - ‘Could not extract GR\_EMIS\_001 file’ on CMAQ and I was wondering if you had any new insight since you posted the error here. My post is at [Could not extract GR\_EMIS\_001 file in CMAQ run](https://forum.cmascenter.org/t/could-not-extract-gr-emis-001-file-in-cmaq-run/1497). Thanks!

Just for grins, what does M3Tools program _m3stat_ say about `ALD2` for 2020132:010000 in _GR\_EMIS\_001_?
