8Lufthansa takes active part in monitoring our
atmosphere
- Since more than 9 years
- continuous measurements on each flight
- onboard of 3 A340-300 long haul aircrafts of
atmospheric O3 and H2O
Significance Cloud Formation, Climate Research,
Chemistry (OH)
9MOZAIC Operation
- 2.500 Flights per year (5000 vertical profiles)
- 19942002 19.000 flights with O3/H2O
instrumentation - 130.000 flight hours of O3 and H2O data
- 2001-2002 500 flights with additional CO
- 500 flights with additional NOy
- 200 flights with
additional CO/NOy - 5 Long-range Aircraft (A340-300) operated by
- Lufthansa (21), Air France, Austrian Airlines,

Civil Aircraft for the Regular Investigation of
the atmosphere Based on an Instrument Container
An European atmospheric research project operated
by Lufthansa
- 1,6 t
- as of May 2004
- planed operating time 10 years
