The overall objectives of the project are:
To determine by measurements and analysis
the relative contribution from air traffic exhaust emissions
to the composition of the lower stratosphere and upper troposphere
at altitudes between 9 and
13 km within and near the flight corridor over the North Atlantic.
To assess the effects of air traffic
emissions in that region in relation to clean background concentrations
and pollutant concentrations from various sources and to analyse
their importance for changes in ozone, oxidizing capacity,
aerosols and clouds.
