| Abstract |
The free troposphere and lower stratosphere play a key
role in global change.
The proposed project aims to further develop and apply an
instrumented high flying aircraft (13-14 km) to perform
fast response chemical and dynamical measurements in
process studies connected to upper tropospheric and lower
stratospheric chemistry in middle and high northern
latitudes. Thus, a group of institutes has been involved
that represents the state of the art in the development
of airborne instrumentation for the study of multiphase
atmospheric chemistry. The STREAM project
(Stratosphere-TRoposphere Exchange study by Aircraft
Measurements) builds upon a Dutch-German initiative,
which has resulted in a successful measurement campaign
in the Arctic lower stratosphere in February 1993. During
this first phase of the project numerical models have
been developed or adapted to support the analysis of the
measurement results.
