| Abstract: | Near-surface atmospheric ozone measurements were carried out at Barrow, Alaska (71°, 19 N, 156°W), from January 1965 to September 1967. Ozone was continuously monitored by microcoulombmetric analysis at a level 2 m above the ground. Daily ozone concentrations near the ground varied from 7 to less than 1 pphm by volume. Highest concentrations occurred in the spring and showed sharp increases lasting from several hours to a few days. These sudden rises in ozone concentration correlated with storm front passages. The concentration of surface ozone from late spring through the sumer and fall showed less variability from day to day than in the spring. The lowest ozone concentrations occurred from late May to early June. |
