Hi all,

Is there a user manual for CMAQ ISAM version 5.0.2? I could find the manual for CMAQ 5.0.2 base model ([https://www.airqualitymodeling.org/index.php?title=CMAQ\_version\_5.0\_(February\_2010\_release)\_OGD](https://www.airqualitymodeling.org/index.php?title=CMAQ_version_5.0_%28February_2010_release%29_OGD)) and the later version of ISAM ([CMAQ/CMAQ\_UG\_ch11\_ISAM.md at main · USEPA/CMAQ · GitHub](https://github.com/USEPA/CMAQ/blob/main/DOCS/Users_Guide/CMAQ_UG_ch11_ISAM.md)), but could not find one for CMAQ-ISAM v5.0.2.

All the best,  
Tristan
