DescriptionAtmospheric ozone concentrations have been monitored at a subalpine forest ecosystem site, 3180m above mean sea level (msl), and at a 2680m msl forest-steppe ecotone site 15km to the southeast. Ozone concentrations were monitored at three heights above the ground on a 30m tower at the higher elevation site, and on a 10m tower in a large meadow downwind of this site. The research reported here concentrates on the data for the first six months of 1990-1994. The diel amplitude of ozone concentrations is very small in winter, increasing as the seasons advance to June. Following snowmelt in late May or June, the nighttime minima decrease under the forest canopy. The highest monthly mean ozone concentrations occur in April or May, depending on the year. Episodal high concentrations were recorded during spring months when upper level atmospheric low pressure troughs and cut-off low centers occurred. These contributions peak in May, and add about 10% to normal May background ozone concentrations, varying widely from year to year. Spectral representations of ozone concentrations, illustrate the suppression of the diel peak during spring months, when stratospheric-tropospheric intrusion patterns show no significant diel cycle.
