| Abstract | (Receiued 22 July 1976) AMrrct-Direct photolysis of 0s end quenching of O(‘D) by N2 provide abundant sources of fast oxygen atoms for the Earth’s lower atmosphere. The concentration of atoms with energy above 0.7 eV may exceed the concentration of O(‘R) for all altitudes below 18 km and these atoms may play an important role in lower atmospheric chemistry. Distribution functions for CX3P) are given for the energy interval 0.1-1.3 eV, for a range of altitudes from 0 to 62 km. Major attention has focussed in recent years on the chemistry of the terrestrial stratospkere, with particular emphasis on atmospheric ozone. Ozone is formed by reactions of 0 with Oz., with oxygen atoms liberated by photolysis of either O2 or 0,. The bulk chemistry was described some 40 yr ago by Chapman (1930), who identified photolysis in the Nerzberg continuum, hv + 0, + O(‘P) + OPF) as the primary source of odd oxygen, with o+o,+ 202 (2) as the predominant sink. The ~~~entration of O(‘P) is maintained in Chapman’s scheme by a combination of the source-sink reactions (1) and (2), and the exchange reactions |
