| Zusammenfassung |
| The radical chemistry of the lower troposphere was investigated
during the ZEPTER-2 field campaign at Lake Constance in October/
November 2008, using the unique capabilities of a modified
Zeppelin NT as an airborne measurement platform. The Zeppelin
was equipped with in-situ instruments for measurement of OH and
HO2 radicals, the main radical precursors (O3, HONO, HCHO),
photolysis frequencies, and prime reactants (NOx, CO, VOCs) of OH.
The instrumentation has been used to chemically characterize the
planetary boundary layer and the lower free troposphere. Vertical
profiles of the trace gases were observed at altitudes up to 1000m
above different land surfaces, including Lake Constace, the city of
Ravensburg and forests. In this presentation technical details of the
measurement platform Zeppelin NT will be presented as well as first
results of the HOx radical measurements. |
