An estimate of the rate of this termination step to the cycling of atomic oxygen back to ozone can be found simply by taking the ratios of the concentration of O 2 to O 3 . The termination reaction is catalysed by the presence of certain free radicals, of which the most important are hydroxyl (OH), nitric oxide (NO) and atomic chlorine (Cl) and bromine (Br). In the second half of the 20th Century the amount of ozone in the stratosphere was discovered to be declining, mostly because of increasing concentrations of chlorofluorocarbons (CFC) and similar chlorinated and brominated organic molecules . The concern over the health effects of the decline led to the 1987 Montreal Protocol , the ban on the production of many ozone depleting chemicals and in the first and second decade of the 21st Century the beginning of the recovery of stratospheric ozone concentrations.
If you include on that list of things I could have regardless of funds and logistics to move an instrument, I would include regardless of effort too. I would need a clone of myself (sorta like a Data) who would need no rest. If I had a Data, then I would say a stick burner, Texas style. No reverse flow. I’d use this solely for briskets and pork butts. For chicken, I would use a BGE but tile it coral sea blue (like the Komodo Kamado on my laptop wallpaper). Honestly, I can’t bring myself to buy a BGE because the tone of green doesn’t move me emotionally and because I can’t afford it. But that is a really good cooker.
