Hi,
I am using 2018gc platform and running script “Monthly\_area\_Q1\_livestock\_12US1\_2018gc\_cb6\_18j\_20210315161542.csh”.
I notice that one of the listed input file is not included in the data I downloaded from [https://gaftp.epa.gov/Air/emismod/2018/](https://gaftp.epa.gov/Air/emismod/2018/)
Is there anyone know how could I get GSREFTMP\_R (should be located as /ge\_dat/speciation/spec\_parts/gsref\_nh3\_fert\_2014v1\_platform\_17jan2017\_v0.txt ) file listed in the script?
Thanks!

And also the SUB\_SEC\_SOURCES (/2018gc\_cb6\_18j/inputs/sa/source\_groups\_nonroad\_gas1\_diesel2\_18feb2021\_v0) for running Monthly\_Nonroad\_Q2\_12US1\_2018gc\_cb6\_18j\_20210317141844.csh is missing.
