| Zusammenfassung |
| Recently it was discovered that over the Middle East
during summer ozone mixing ratios can reach a pronounced maximum in the
middle troposphere. Here we extend the analysis to the surface and show that
especially in the Persian Gulf region conditions are highly favorable for
ozone air pollution. We apply the EMAC atmospheric chemistry-climate model
to investigate long-distance transport and the regional formation of ozone.
Further, we make use of available in situ and satellite measurements and
compare these with model output. The results indicate that the region is a
hot spot of photochemical smog where European Union air quality standards
are violated throughout the year. Long-distance transports of air pollution
from Europe and the Middle East, natural emissions and stratospheric ozone
conspire to bring about relatively high background ozone mixing ratios. This
provides a hotbed to strong and growing indigenous air pollution in the dry
local climate, and these conditions are likely to get worse in the future. |
