Typo in Troe formulation of K_PRPE_OH in GEOSCHEM_K.m

[MaggieMarvin]

Hi Glenn,

Just wanted to let you know there's a typo in the Troe formulation of K_PRPE_OH in GEOSCHEM_K.m that must have been carried over from earlier versions of the CB mechanisms. It's at line 113, and the 2 here should be positive, not negative:

krx(:,i) = (LPL./(1+LPL./HPL)).*0.5.^(1./(1+(log10(LPL./HPL)).^2));

I think this is the only reaction affected in the GEOS-Chem mechanism.

Best,
Maggie

Thanks! What’s PRPE? Katie, if you have some time could you please confirm this since you built that mechanism? ~Glenn From: Maggie Marvin <notifications@github.com> Sent: Thursday, August 22, 2019 11:14 AM To: AirChem/F0AM <F0AM@noreply.github.com> Cc: Subscribed <subscribed@noreply.github.com> Subject: [EXTERNAL] [AirChem/F0AM] Typo in Troe formulation of K_PRPE_OH in GEOSCHEM_K.m (#8) Hi Glenn, Just wanted to let you know there's a typo in the Troe formulation of K_PRPE_OH in GEOSCHEM_K.m that must have been carried over from earlier versions of the CB mechanisms.

No problem! It's a lumped species for alkenes with at least 3C. I'm looking at VOC reactivity with GEOS-Chem, and it just happened to pop up.

Glenn and Maggie, Yes that should be positive, not negative. Looking back, I am not sure what I wrote this one out explicitly. I hope this doesn’t overly impact your work. ~Katie From: "Wolfe, Glenn M.
