| Zusammenfassung |
| The planetary boundary layer (PBL) is the chemically most active and complex part of the
atmosphere where freshly emitted reactive trace gases, tropospheric radicals, atmospheric
oxidation products and aerosols exhibit a large variability and spatial gradients. In order to
investigate the chemical degradation of trace gases and the formation of secondary pollutants
in the PBL, a commercial Zeppelin NT was modified to be used as an airborne
measurement platform for chemical and physical observations with high spatial
resolution.
The Zeppelin NT was developed by Zeppelin Luftschifftechnik (ZLT) and is operated by
Deutsche Zeppelin Reederei (DZR) in Friedrichshafen, Germany. The modification
was performed in cooperation between Forschungszentrum Jülich and ZLT. The
airship has a length of 75 m, can lift about 1 ton of scientific payload and can be
manoeuvered with high precision by propeller engines. The modified Zeppelin can carry
measurement instruments mounted on a platform on top of the Zeppelin, or inside the
gondola beneath the airship. Three different instrument packages were developed to
investigate
a. gas-phase oxidation processes involving free radicals (OH, HO2)
b. formation of secondary organic aerosols (SOA)
c. new particle formation (nucleation)
The presentation will describe the modified airship and provide an overview of its technical
performance. Examples of its application during the recent PEGASOS flight campaigns in
Europe will be given. |
