Zusammenfassung |
Ozone holds a certain fascination in atmospheric science. It is ubiquitous
in the atmosphere, central to tropospheric oxidation chemistry, yet harmful
to human and ecosystem health as well as being an important greenhouse gas.
It is not emitted into the atmosphere but is a byproduct of the very
oxidation chemistry it largely initiates. Much effort is focused on the
reduction of surface levels of ozone owing to its health and vegetation
impacts, but recent efforts to achieve reductions in exposure at a country
scale have proved difficult to achieve owing to increases in background
ozone at the zonal hemispheric scale. There is also a growing realisation
that the role of ozone as a short-lived climate pollutant could be important
in integrated air quality climate change mitigation. This review examines
current understanding of the processes regulating tropospheric ozone at
global to local scales from both measurements and models. It takes the view
that knowledge across the scales is important for dealing with air quality
and climate change in a synergistic manner. The review shows that there
remain a number of clear challenges for ozone such as explaining surface
trends, incorporating new chemical understanding, ozone–climate coupling, and a better assessment of impacts. There is a clear and present need to
treat ozone across the range of scales, a transboundary issue, but with an
emphasis on the hemispheric scales. New observational opportunities are
offered both by satellites and small sensors that bridge the scales. |
