The Pollution From Aircraft Emissions in the North Atlantic Flight Corridor (POLINAT)
projects were undertaken to investigate the impact of aircraft engine exhaust emissions on
the state of the atmosphere in the North Atlantic flight corridor. Changes in the composition
of the lower stratosphere and upper troposphere from aircraft emissions are identified from
combined measurements and model analyses. Measurements were performed using the
Deutsches Zentrum für Luft‐und Raumfahrt Falcon research aircraft and a Swissair B‐747 …

The POLINAT project (phase 1) was performed 1994 to 1996 within the Environment
Research Programme of the European Commission. POLINAT-2 is being performed now
since April 1996. The objectives of POLINAT-1 and-2, the methods used, the measurements,
and some selected results are described. Details are given on the measured background
concentrations, the emission indices of several aircraft, comparisons between modelled and
measured data, and the impact of the emissions within the North Atlantic flight …
