The MOZAIC system has been developed for automatic ozone, water vapour and
temperature measurements during in service flights aboard A340 aircraft.
MOZAIC is an European cooperation between the 'Laboratoire d'Aerologie' of
CNRS (Centre National de la Recherche Scientifique) and Airbus Industrie.
Several organizations participate to this project : the KFA (Kennforschungsanstalt)
Julich and the Max Planck Institut (MPI) Mains in Deutschland, Meteo France,
the Cambridge University in England and the Tenerife University in Portugal.
For more information on the MOZAIC Program and the MOZAIC Data Base,
see the
MOZAIC site .
Here is the way the files are built:
The box size is 150 m height x 60 seconds time
Data set source:
These data were provided by the 'Measurement of OZone by Airbus In-service
airCraft' (MOZAIC) program.

Data Processing
Files are in three parts:
The averaged values with altitude interval of about 150 m.
The averaged values with a gap of 1 minute.
Averages values with altitude interval of about 150 m.
if (|H1-H| >= 150 meters or |T1-T| >= 60 seconds) then
endif
and so on.
Then the profiles are built with mean values on intervals
of either 150 meters or 60 seconds.
