During August and September 1986, 11 aircraft flights were made over the eastern Pacific Ocean and continental United States. The observations included simultaneous measurements of peroxyacetyl nitrate (PAN) and active nitrogen (NO/sub x/=NO+NO/sub 2/). At altitudes of 4.5-6.1 km in the middle free troposphere, PAN was usually 5-6 times NO/sub x/ in maritime air masses and 2-4 times NO/sub x/ in continental air masses. The observations show that PAN can be a major component of the odd nitrogen budget in the middle free troposphere and confirm that the abundance is mainly governed by long-range transport processes including formation during transport and continental boundary layer to free tropospheric exchange of PAN and its precursors. PAN can be transformed to active nitrogen and peroxy radicals by a variety of physical atmospheric processes that lead to air mass warming. The large ratios of reservoir PAN to active NO/sub x/ imply an important role for PAN in the eastern Pacific remote free troposphere.
