Ozone observed at Whiteface Mountain, NY, may be derived from the stratosphere, photochemical production from pollutant NO/sub x/ and hydrocarbons emitted in urban/industrial areas, with subsequent transport of O/sub 3/ to Whiteface Mountain, and/or photochemical production from NO/sub x/ and hyodrocarbons including terpenes, etc., emitted from vegetation in the vicinity of Whiteface Mountain. The principal objective of this work was to assess /sup 7/Be and /sup 32/P as stratospheric tracers and, if possible, use them to quantify stratospheric O/sub 3/. Other objectives of this program were: to study the relationship between O/sub 3/ and SO/sub 4//sup 2 -/, use SO/sub 4//sup 2 -/ as an indicator of photochemical production originating in urban areas, to study the long-range transport of pollutants and try to identify emission sources and establish daily, monthly, and seasonal variations of SO/sub 4//sup 2 -/ and trace elements thus generating a data base to study long-term trends. The salient features of this study were the first determinations of /sup 7/Be/O/sub 3/ ratios in the lower stratosphere and upper troposphere and gathering continuous data of radionuclides /sup 7/Be, /sup 32/P, and /sup 33/P along with O/sub 3/, SO/sub 4//sup 2 -/, and several trace elements. Some of the significant accomplishments of this study are: a quantitative relationships between /sup 7/Be and O/sub 3/ in the stratosphere was established, and it is applied to estimate stratospheric O/sub 3/ on a global and episodic basis; global /sup 7/Be measurements suggest that the stratospheric influx in the northern hemisphere is twice that in the southern; and, the /sup 7/Be//sup 32/P ratios yield an average transport time of approx. 7 days during spring and summer for stratospheric air from tropopause to Whiteface Mountain, supporting tropopause folding as the predominant mechanism of stratospheric-tropospheric exchange during spring and summer.
