a Preferred values from the Master Chemical Mechanism, MCM v3.3 ((Jenkin et al., 1997; Saunders et al., 2003)) via http://mcm.leeds.ac.uk/MCM, b(Morin et al., 2016), c(Romanias et al., 2015), d(Atkinson, 1990). The values of k4 are for 298 k and 760 torr. Units of k4 are ×10–12 cm3 molecule–1 s–1. Selection and calculation of J5 is detailed in the SI. Values of kB are calculated as k4[OH] + J5 with temperature dependent parameters from Atkinson and Arey (2003) using average daytime (08:00–18:00) 10 m agl temperatures (5°C, 12°C, and 25°C for winter 2011, spring 2015, and summer 2015) and seasonal Northern Colorado OH concentration ranges (details in section 3.2.1).
