| Zusammenfassung |
| Goal of the project CARIBIC (Civil Aircraft for the Regular Investigation of
the atmosphere Based on an Instrumented Container) is to carry out regular
and detailed observations of atmospheric composition (particles and gases)
at cruising altitudes of passenger aircraft, i.e. at 9–12 km. Continuous,
fast measurement of CO is indispensable for the chemical characterization of
encountered air masses, for the detection of plumes of polluted air and for
studying troposphere-stratosphere transport. CO is measured by a commercial
resonance fluorescence UV instrument modified for the use onboard passenger
aircraft. Modifications were necessary to optimize the instrument
reliability allowing unattended operation for several days. The instrument
has a precision of 1–2 ppbv at an integration time of 1 s. The response
time to reach 63.2% signal strength is 2 s. We describe the
modifications of the instrument, the experiences made during its operation
since December 2004, the quality control of CO measurements onboard CARIBIC,
and suggest a regular service routine that guarantees long-term high-quality
data. |
