ICON and BCON conversion from CB06 to CRACMM2

Hello,

I looked for any related discussions on converting ICON and BCON files from the CB06 mechanism to CRACMM2, but couldn’t find relevant guidance.

From what I understand, setting ICON and BCON to use the default profiles (even just to generate a skeleton that could later be populated with values from another model ) does not consider the CRACMM2 mechanism. Is that why the map2chem directories exist in both the ICON and BCON folders?

I attempted to run the conversion scripts, but they appear to require variables like RH, P, and TA, referenced in SpecDef_cracmm1_aq_derived_from_cb6r5m_ae7_aq.txt. However, I don’t believe ICON or BCON provide these fields.

Any instructions or recommendations for preparing and running CMAQ 5.5 with CRACMM2 would be greatly appreciated.

Thanks!

I guess, I can just comment those variables in the txt file. But I was wondering if this would introduce a problem later on.

Does anyone have a CRACMM2 version of this: “avprofile_cb6r3m_ae7_kmtbr_hemi2016_v53beta2_m3dry_col051_row068.csv”
