The CARIBIC Lufthansa aircraft project and its investigation of Eyjafjallajökull's ash clouds — •David Walter1,2, Armin Rauthe-Schöch1, Klaus-Peter Heue1, Carl Brenninkmeijer1, and the CARIBIC-Team3 — 1Max Planck Institute for Chemistry, Mainz, Germany — 2Institute of Environmental Physics, Heidelberg, Germany — 3various institutes, Europe
CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) observes physical and chemical processes in the Earth's atmosphere using a measurement container aboard a Lufthansa Airbus 340-600. A special inlet system is mounted on the aircraft with probes for trace gases, water vapor and aerosol particles. It also includes a DOAS system for remote sensing and a video camera for cloud monitoring. -- www.caribic.de
With this unique observatory, three special measurement flights were performed in April and May 2010 to explore the ash cloud of the Icelandic volcano Eyjafjallajökull. The concentration of the ash particles was measured with four particle counters. Simultaneously the amount of SO2 and BrO were observed with the DOAS system. Further instruments measured many other trace gases such as CO, CO2, mercury and ozone. Additionally, aerosol and air samples were collected for detailed post-flight analysis in different laboratories.
In this presentation, CARIBIC is briefly presented and the results of the Eyjafjallajökull flights discussed and compared with satellite data.
