Global mitigation gain
The total mitigation gain arising from environmental flight planning
will be estimated on global and annual scale. Based on archetypical
weather situations and individual gains from environmental flight planning
(WP3) with the help of the occurrence frequencies of the selected weather
situations total gain can be extrapolated.
Gain from environmental flight planning for individual archetypical situations
The emissions occurring during the optimised flights will be
used to form emissions inventories. The impact of these emissions
on the atmospheric composition (including aerosols) and the
associated radiative forcings will be simulated by
Chemisty Transport Models (CTMs) for the various selected weather
situations. To this end the CTMs are forced by the meteorological
data generated and analysed before. The output of these simulations
serves to evaluate the mitigation gains obtained by environmental
flight planning on the basis of the climate cost functions.
Simulating of contrail and contrail cirrus
Finally, the performance of the models with respect to simulating contrail
and contrails cirrus and calculating the associated radiative forcings will
be evaluated by means of analysing satellite data.
