The absolute uncertainty of OH reactivity measurement (2? ) mainly depends on following factors: (1) uncertainty of the anemometer, which is 2% of reading from the manufacture specification for Model 8455-03 Air Velocity Transducer and 10% for the temperature and pressure correction; (2) uncertainty of the regression coefficients , which is 15% when the decay is less than 2 s?1, and 5% when the decay is about 6 s?1; (3) the statistical precision of the fluorescence signals, which are about 100 cts s?1 for 15 s at the furthest point, for an uncertainty of 4%; and (4) uncertainty of the measured position of the wand, which is less than 1%.'
