Description:
The present investigation provides some information related to the problem of ozone destruction by nitric oxide emission from high flying vehicles. It is found that CO and H2O can counteract NO destruction of O3 in laboratory simulations. The addition of CO and H2O to aircraft exhausts could be a practical means of reducing the damage of the UV-filtering ozone layer. It is also discovered that NO is not regenerated as it destroys ozone, except at low stratospheric pressures. It is believed that the presence of H2O and CO gives rise to a series of reactions which provide a kinetically competitive pathway for the NO, causing it to go into NO2 production via these substrates rather than via O3.
