ISAM emission streams

Hi everyone

I am using CMAQ5.4 for ISAM runs. I am facing problem in grouping emissions together in the. ISAM control file (for example I want to group agricultural fires and wildfires together). When I run it with just EGU it runs fine but when I include other categories like fire or non IPM it doesn’t run. This is how I am defining the tag names, regions and emission streams. I don’t know if there is a specific naming convention but the tutorial suggested that you can group emissions together.

TAG NAME |EGU
REGION(S) |EVERYWHERE
EMIS STREAM(S) |PT_EGU

TAG NAME |FIR
REGION(S) |EVERYWHERE
EMIS STREAM(S) |PT_AGFIRES, PT_FIRES, PT_WILDFIRES, PT_OTHFIRES

TAG NAME |CMV
REGION(S) |EVERYWHERE
EMIS STREAM(S) |PT_CMV_C3, PT_CMV_C1C2

This is the error that I am getting

  User specified ISAM tag - PT_CMV_C3 - not found in available emissions streams
  User specified ISAM tag - PT_CMV_C1C2 - not found in available emissions streams

 *** ERROR ABORT in subroutine ISAM_STREAMS on PE 319
 INCORRECT Emissions Stream used in ISAM control file

I would really appreciate any help or guidance on the matter! Thank you!

“not found in available emissions streams” means that you do not define this emission steam in your run.cctm.csh. Please go to the emission section of run.cctm.csh and then edit the emission stream for matching these in isam control file. Then the model is good to go.
