From page 35...
... These suggestions are applicable to any future research program on the atmospheric effects of stratospheric aircraft, whether it is carried out by NASA or by others. The fundamental reaction processes that occur in engines are not understood well enough to determine the potential magnitude, phase, and composition of emissions.

From page 36...
... Very little information exists about the flux of aerosol particles and precursors into the stratosphere from the troposphere at low latitudes. PAEAN recommends continued emphasis on characterizing the global distribution and sources of lower stratospheric and upper tropospheric aerosol, in order to properly gauge the relative impact of aircraft particle emissions.

From page 37...
... PAEAN recommends that the next generation of stratospheric assessment models include chemical-dynamical feedbacks, higher vertical and horizontal resolution, and accurate representation of relevant tropospheric processes.
