From page 38...
... continued funding for AEAP is highly uncertain, the panel believes it is important to also express some general concerns about the future of research on the atmospheric effects of aviation, both subsonic and supersonic. These concerns are raised to help ensure that those responsible for making decisions about future research on this topic are fully aware of the benefits to be gained from maintaining a focused research program.

From page 39...
... U.S. scientists played a significant role in the production of the new IPCC assessment Aviation and the Global Atmosphere; but without a continuing research program on this issue, it is likely that they will play a much smaller role in any future assessments.

From page 40...
... Also, as noted earlier, AEAP has helped sponsor several large field programs featuring coordinated in situ observations of multiple chemical species, which have led to numerous advances in understanding upper tropospheric and lower stratospheric chemistry. It is important that such programs continue, as they will help improve understanding of both aviation impacts and many other issues.

... These recommendations also apply to future work in assessing aviation's climate impacts, and thus the panel encourages more coordination between the various agencies charged with studying atmospheric chemistry and climate, as well as more attention to addressing concerns about improving U.S. supercomputing capabilities.
