Mitigation studies
With simplified mitigation studies, the environmental benefit of
simplified air traffic management (ATM) measures will be quantified.
General principles of environmentally-optimized flight for defined
timescales and climate effects will be formulated.
For this purpose pseudo-emission inventories will be computed accounting
for effects of simplified ATM measures on emissions and environment. A
first set will be based on pre-existing knowledge about the spatial dependence
of the climate impact of aircraft emissions. For example, flight levels
will be shifted upward or downward globally or only for selected regions.
A second set will incorporate our findings from other workpackages in REACT4C.
Using atmosphere general circulation models (GCMs), chemistry-transport
models (CTMs) and chemistry climate models (CCMs), the impact of the
mitigation possibilities from con-trails, particles and changes on the
chemical composition of the atmosphere will be studied. Finally, the
climate impact of the various ATM options manifested in the
pseudo-inventories will be determined.
