| Zusammenfassung |
| In situ measurements of CO and NOy from CARIBIC as well as satellite observations from
various platforms indicate that the chemical composition of the troposphere over East Asia is
strongly affected by pollution from the lower troposphere.
We will use a combination of in-situ data, satellite observations and backward trajectories to
investigate the transport processes for pollutants to the upper troposphere over East Asia.
Based on a case study we show that convection and subsequent long range transport from the
polluted boundary layer over India strongly affects the upper troposphere over East Asia.
Enhancements of short lived non-methane hydrocarbons, NO and NOy as well as CO and
their correlations to ozone indicate a strong contribution to the upper tropospheric
ozone.
On the base of satellite observations we find, that the region of far east Asia plays a key role
for the chemical composition of the upper troposphere on global scales. |
