Total ozone loss rate in UV photolysis experiments without using a range of lamp flux values in the model, compared with the observed loss rate in CB03 experiments.
Modeled rates of ozone formation and loss over time in CB03 bulb experiments (a) in UV light without , (b) in UV light with of , and (c) in visible light. The initial ozone concentration is for (a) and (b) and is for (c). Note the difference in the and scales for (c).
Triple isotope plot of ozone composition in experiments (stars) and selected model scenarios (as labeled). The experimental data points have been converted to the and scale and adjusted for differences in the initial isotopic composition (less than 3‰). A linear fit to the experimental data has a slope of 0.64, while the average slopes of the model predictions range from 0.70 to 0.92 (see Table II).
Change in “slope” of the ozone fractionation as is added, comparing the experimental results of CB03 with several model scenarios (as labeled).
Scenario 3AD combines isotope effects in reactions (2.2), (2.3), and (2.7a) for (a) the experiments without and (b) the experiments with . The stars are CB03 data with 10% error bars shown in (b). The sensitivity of the modeled slopes in (b) to the choice of “final” time is discussed in the text.
Change in of ozone over time in the CB03 visible light experiments and in all model scenarios. The experimental data points have been adjusted for differences in the initial isotopic composition (less than 2‰), and the initial composition for all model runs was derived from the data.
