A Review of NASA's 'Atmospheric Effects of Stratospheric by National Research Council, Division on Earth and Life

By National Research Council, Division on Earth and Life Studies, Environment and Resources Commission on Geosciences, Panel on Atmospheric Effects of Aviation

The NRC Panel at the Atmospheric results of Aviation (PAEAN) was once demonstrated to supply suggestions to NASA's Atmospheric results of Aviation application (AEAP) by way of comparing the appropriateness of the program's learn plan, appraising the project-sponsored effects relative to the present nation of medical wisdom, settling on key clinical uncertainties, and suggesting examine actions prone to lessen these uncertainties.

Over the previous couple of years, the panel has written periodic reports of either the subsonic aviation (Subsonic Assessment-SASS) and the supersonic aviation (Atmospheric results of Stratospheric Aircraft-AESA) parts of AEAP, together with: An period in-between overview of the Subsonic overview venture (1997); An intervening time evaluate of AEAP's Emissions Characterization and Near-Field Interactions components (1997); An meantime overview of the AESA undertaking: technology and development (1998); Atmospheric results of aviation: A overview of NASA's Subsonic overview venture (1998). This record constitutes the ultimate evaluate of AESA and should be the final file written via this panel. the first viewers for those experiences is this system managers and scientists affiliated with AEAP, even if sometimes the subjects mentioned are of curiosity to a much wider audience.

Discrepancies between observed and predicted daytime concentrations of HOx have been resolved to some extent by inclusion of heterogeneous hydrolysis reactions of chlorine and bromine nitrate. , 1999). It should be recalled that each component of the photochemical model is dependent on the others so that the NOx/NOy discrepancy may reveal a problem in the underlying assumptions that allow good agreement for other components. , 1997). , 1999). , earlier concerns about "missing chemistry" have abated, particularly for the region below ~22 km.

However, it should be noted that other "elements" of the research program (namely, laboratory studies, operational scenarios, near-field interactions, and emissions) have all been important components of the overall assessment of this issue. Gas-Phase Aircraft Emissions An assessment of the stratospheric impact of HSCT operations requires an accurate inventory of the emissions from such future aircraft. It has been suspected since the early 1970s that emissions, particularly of nitrogen oxides, from stratospheric aircraft could affect the level and distribution of stratospheric ozone.
