Is HONO (nitrous acid) represented in the WACCM6 tsmlt chemistry set?

[nstant]

To Whom this may concern,

Looking through the chem_mech.doc it appears that HONO (nitrous acid) is not represented as a chemical species in the model. I was wondering if there is any confirmation if that is correct, and if it is which documentation/papers should I look at? The compset used in this simulation was BW1850.

Sincerely,

Noah Stanton

HONO is not represented. You can check the chemistry of any case from the case directory by looking under the CaseDocs subdirectory at the file chem_mech.doc.

There is some discussion of the chemical mechanisms available in the CAM6 user guide, here:

10. Chemistry specific modifications — camdoc documentation

The full description is in this paper:

Emmons et al. (2020). The Chemistry Mechanism in the Community Earth System Model Version 2 (CESM2). Journal of Advances in Modeling Earth Systems, 12(4), e01882. https://doi.org/10.1029/2019ms001882

Thank you for the quick response Mike!
