LARGE SCALE ATMOSPHERIC COMPOSITION FIG. 3.3: Reduction in the ozone formation due to the use of alternate fuels at the 2026 horizon has been extended to include ethane, PAN and CH 3 CO 3 . The NMH emitted by aircraft are assumed to follow an oxidation cycle with rates identical to ethane, which is a fair approximation given the rather short lifetime of NMH in the upper troposphere. The MOBIDIC model uses a dynamical forcing (wind components and temperature) from a transient climate scenario of the ARPEGE-Climat model which takes into account the evolution of trace gases having an impact on radiation and chemistry. The impact of using alternate fuels is first seen on the NOx atmospheric content. At the 2026 horizon the NOx content would decrease by about 2% at cruise altitude in the NH (about 3 pptv). Consequently less ozone would be produced by the NOx aircraft emissions, an ozone decrease of 200 ppt is calculated at the tropopause level at mid-latitudes. In relative terms the ozone production would decrease by about 2.4% , with little seasonal and latitudinal variations (see Fig. 3.3). We can conclude that the used of alternate fuel (50% blend of agro-fuel and Jet A-1 kerosene) should have a very modest impact on the ozone atmospheric content. According to our model calculation, the ozone production at the 2026 time horizon would decrease by about 2.4 % when alternate fuel is used. This is a very small number that is at least one order of magnitude lower that variations due to natural variability or changes that are expected to follow the decrease in the stratospheric chlorine loading. In addition, this results is quite uncertain because the NOx index of emission for alternate fuel appears to be very variable from one engine type to another, and also according to the power regime used. Thus, the NOx emission reduction is a result of a delicate balance directly related to the details of the fleet scenario. Most of the NOx decrease seems however to be related to the lowest fuel consumption in the alternate scenario compared to the reference one. 190 Jan. 2010 – Dec. 2011
