The contribution of stratosphere-to-troposphere transport to high surface ozone (O3) along the Colorado Front Range during spring of 1999 is examined using lidar and surface measurements. A deep tropopause fold brought ˜215 ppbv of O3 to within 1 km of the highest peaks in the Rocky Mountains on 6 May 1999. One-minute average O3 mixing ratios exceeding 100 ppbv were subsequently measured at a surface site in Boulder, and daily maximum 8-hour O3 concentrations greater or equal to the 2008 NAAQS O3 standard of 0.075 ppmv were recorded at 3 of 9 Front Range monitoring stations. Other springtime peaks in surface O3 are also shown to coincide with passage of upper level troughs and dry stable layers aloft. These results show that the stratospheric contribution to surface ozone is significant, and can lead to exceedance of the 2008 NAAQS O3 standards in a major U.S. metropolitan area.
