Abstract:A global air traffic emissions database is an essential tool for both policy makers and climate change
scientists. Since the last comprehensive aircraft emissions inventories were developed in 1992, an
update is necessary. This need is being addressed in the USA through a project entitled SAGE and in
Europe through a project entitled AERO2K. Both Europe and the USA have agreed to collaborate on
these similar projects. The agreement resulted in the exchange of flight movement data in order to
realise an air traffic movement inventory, the essential starting point for estimating global aviation
emissions. The objective of the inventory in both projects is to provide 4-D flight trajectories
(latitude, longitude, altitude and time) using as much measured data as possible. In AERO2K, to
supplement the collection of data, schedule data from the Back Aviation database were also used,
complemented by airspace route structure information, where available. Similarly, in SAGE,
measured data were augmented by schedule data from the worldwide Official Airlines Guide (OAG),
complemented by a vertical and horizontal track dispersion model, which was developed from actual
measured 4-D trajectory data. This paper details the aircraft movements data in AERO2K and SAGE.
