Table 2. Correlations between total or missing OH reactivity and isoprene or MVK+MACR+ISOPOOH OH reactivity.
| Total OH reactivity | Missing OH reactivity | Regimes of missing reactivity | ||
|---|---|---|---|---|
| Isoprene OH reactivity | ||||
| y=(7.5±0.5)x+63.4 | PCC=0.82 | y=(6.1±0.4)x+60.2 | PCC=0.76 | High |
| y=(2.2±0.1)x+26.0 | PCC=0.75 | y=(1.0±0.1)x+23.6 | PCC=0.46 | Medium |
| y=(0.8±0.04)x+6.8 | PCC=0.56 | y=(−0.3±0.04)x+5.3 | PCC=−0.27 | Low |
| MVK+MACR+ISOPOOH OH reactivity | ||||
| y=(17.2±1.4)x+60.2 | PCC=0.74 | y=(13.7±1.4)x+58.4 | PCC=0.69 | High |
| y=(14.8±0.6)x+22.1 | PCC=0.79 | y=(8.5±0.6)x+19.6 | PCC=0.62 | Medium |
| y=(8.7±0.6)x+6.9 | PCC=0.49 | y=(−4.2±0.6)x+5.3 | PCC=−0.27 | Low |
Linear fit parameters and PCC for correlations between total or missing OH reactivity to isoprene or isoprene products (MVK+MACR+ISOPOOH) OH reactivity as pictured in were calculated for high (dry season, >60 s−1), medium (dry season, <60 s−1) and low (wet season) missing OH reactivity regimes.
