Surface nitric oxide mixing ratios were measured in the equatorial Pacific region using a chemiluminescent detector. The average NO mixing ratio was about 4 pptv during noontime conditions for nine days of measurements. These NO mixing ratios, which are much lower than any previously reported, imply that the O 3 production rate due to CO and CH 4 oxidation may be less than previously believed. They also imply smaller OH/HO ratios as a consequence of the lower HO 2 to OH² conversion by NO.
