How to make sure new emissions have been read in the HEMCO?

Description of your issue or question

I was trying to include an off-gassing emission for furfural (one of VOCs that haven't been included in the GEOS-Chem yet). Unlike GFED/CEDS, which we could tell if they are read in the GC.log (see below), I am not sure if my newly added emission data is read or not. I was wondering if there is any way to figure it out? The setting of building emissions can be found in the HEMCO_Config by searching BUILDING or LIXU. Please let me know if there is anything else you need to further check. Thanks!

Thanks for writing @jinlx. You can turn on Verbose: 3 in the HEMCO_Config.rc file. This will write out a lot of data but you will see if your emissions are being read if you search through the log file.

NOTE: In HEMCO 3.7.1/GEOS-Chem 14.2.1 we have replaced e.g. Verbose: 3 with Verbose: true. It will have the same effect.

Thank you Bob! This very helpful! After doing so, I got following related lines in the log output. In my understanding, the building emission was skipped due to some conflicts of CEDS data. Is this any way to bypass influence from CEDS and read in the building emissions as well? Thanks! ~Lixu

Added the following option:  BUILDING:        true

Register_Base: Checking BUILDING
HEMCO: Entering Get_targetID (HCO_CONFIG_MOD.F90) ( 4)
Skip container BUILDING because of CEDS_GBDMAPS_FURFUR_bIND
HEMCO: Leaving Get_targetID (HCO_CONFIG_MOD.F90) ( 4)
Container ID     :         2004
Assigned targetID:         -999

My corresponding setup in the HEMCO_COnfig is also provided just in case.

Sorry for the late reply @jinlx. I think you can try increasing the Hierarchy value, which should cause HEMCO to take the BUILDING emissions over the CEDS emissions. See:
