OTHER_COMMENTS: Final Data. OH Reactivity signals from individual 20 or 30 second scans have been averaged together for 60 seconds. - This averaging is needed because quenching in air humidity at low altitudes decreased the signal significantly; - summing the signal over 60 seconds overcame this statistical hurdle. - Increasing the summation time to 120 seconds gave the same OH Reactivity as the 60-second average to within 10%. - For details, please see Mao et al., Atmos. Chem. Phys., 9, 163-173, 2009.
