UNCERTAINTY: OHR measurement uncertainty +/- 15% at 2 sigma confidence, with 0.4 s^-1 in the zero uncertainty ULOD_FLAG: -7777 ULOD_VALUE: N/A LLOD_FLAG: -8888 LLOD_VALUE: N/A DM_CONTACT_INFO: William H.

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.
