OTHER_COMMENTS: Final Data. OH reactivity signals from individual 20 or 30 second scans have been added together for 60 seconds.
- Summing these signals compensated for the signal decrease due to quenching in the humid air at lower altitudes.
- By increasing signal counts, the statistical noise in the calculated decays was reduced.
- Increasing the summation time to 120 seconds gave the same OH reactivity as the 60-second average to within 10%.
- OHR flow tube T and p are needed to convert ambient modeled OH reactivity so that it can be compared to measured OH reactivity.
- This conversion can double the modeled OH reactivity at cold, high altitudes, but has little effect at low altitudes.
- For details, please see Mao et al., Atmos. Chem. Phys., 9, 163-173, 2009.
