Oberpfaffenhofen, Oct - Nov 2008

CONCERT was an aircraft measurement campaign with the DLR Falcon, coordinated by DLR-IPA (Christiane Voigt).
The campaign was performed between October 20 and November 21, 2008, and was divided into two parts, CONCERT-Chemistry and CONCERT-Contrails. The scientific focus of the CONCERT project was set on microphysical, radiative and chemical properties of contrail-cirrus, but the detection of the eruption plume of the volcano "Kasatochi" triggered studies on volcanic gases and aerosol particles in the lowermost stratosphere.

We operated C-ToF-AMS successfully onboard the Falcon during the 6 flights of the first sub-project (CONCERT-Chemistry). For the second part, the rack space was needed for the DLR-IPA aerosol rack. The instruments of our Aerosol and Cloud Physics group (CIP, CCP, FSSP) were operated thoroughout the whole campaign.
