We can define production and loss families for a species (e.g., CH₂Cl₂) in the gckpp.kpp file, and the associated production and loss rates can be archived in the diagnostics. I’m curious if it’s possible to archive the reaction rates for a specific reaction, similar to how P/L rates are archived for individual species. In this case, we want to specifically track and archive the rates for a particular reaction rather than an entire species. Any thoughts? Thank you!

Hi @lshen2009, thanks for writing. You can archive reaction rate diagnostics in the RxnConst history collection, as described here:

@lshen2009: also note that this diagnostic may not be working as expected, see #2329.
