The phrase "a second ozone" is grammatically correct and can be used in written English.
It can be used in contexts discussing multiple layers or instances of ozone, such as in scientific discussions about atmospheric layers or environmental studies.
Example: "The researchers discovered a second ozone layer that had formed due to changes in atmospheric conditions."
Alternatives: "another ozone layer" or "a second layer of ozone".
Since then the analyses have been extended to include more cities, more years of data, and a second pollutant, ozone (O3) (Bell et al. 2004; Smith et al. 2009).
Second, Ozone layer depletion will slow down.
Particle formation in the 0.1-0.2 0.1-0.2size range occurred as soon as ozone was introduced, but the formicrom of particlesize the 0.2-0.3 micrangeize range did noccurred until as leasoonhe second ozone injection occurred.
The roster includes community organizers from across the country: one from a Texas environmental organization, another from the Alaska Public Interest Group, a third from Ozone Action in Washington.
He notes, however, that the team has 8 months of data and is developing a second-generation ozone monitor for ADEOS II, set for launch in 1999.
David Fahey, a physicist at the National Oceanic and Atmospheric Association and the author of a well-known pamphlet on the ozone layer, said the appearance of a second hole in the ozone layer underlined the unpredictability of atmospheric reactions, particularly in the far North.
In fact, a slight increase in HyPer5 signal was noted after the third ozone exposure (15 minute time interval, see below).
Emissions of chlorinated fluorocarbons, or CFCs, once found in aerosol sprays, and other ozone-depleting substances like the soil fumigant methyl bromide produced the first ozone hole over the Antarctic, which was identified in 1985.
The first ozone generator was invented in Germany in 1857 by Werner von Siemens who founded a rather large company that bears his name.
During his final year, Bourtourault did a short research project on the detection of ozone, a second one on the storage of nuclear waste, and a 4-month internship at the state-owned Aérospatiale company, where he worked on nonpolluting anticorrosion treatments.
