Sentence examples for surface ozone from inspiring English sources

It found that globally, average surface ozone would be reduced by about 1 part per billion by volume by 2030.

In 1997, for instance, the E.P.A. moved to reduce surface ozone, a form of pollution caused, in part, by emissions from oil refineries.

The study, by J. Jason West of Princeton and colleagues, simulated a reduction in human-related methane emissions by 20percentt, starting in 2010, and looked at its effects on so-called surface ozone concentrations.

At Earth's surface, ozone is a caustic chemical and a health hazard.

Surface ozone is an environmental issue occurring at several scales, ranging from local to continental.

Thus, it can be concluded that there is a strong association between the ambient temperature and the surface ozone levels.

Modeled estimates of climate change induced increases in near-surface ozone concentrations and accumulated ozone, exposure over a threshold of 40 ppb (ppb hrs), are much larger in southern Europe [ 3].

More hydrogen would lead to more water in the stratosphere, where the ozone layer sits, making it cooler and cloudier, and creating more ice crystals, on whose surfaces ozone-destroying reactions occur.

While the results presented relate to a dataset describing the daily time-series of the concentration of surface level ozone (O3) in urban Berlin, the methods applied are quite general and applicable to a wide range of pollutants and locations.

The low catalytic activity for FP SCWA-TsL can be explained not only by its low CAP content of 51%% but also by high contents of impurity phases such as calcium and nickel fluorides and magnesium silicate blocking an access to active sites of the SCWA surface for ozone molecules.

This illustrates the importance of simulating the large-scale chemical transport as well as local-scale emissions and chemical processes in order to determine surface local ozone concentrations accurately.
