Climatology of diurnal trends and vertical distribution of ozone in the atmospheric boundary layer in urban North Carolina

Vertical measurements of ozone were made on a 610 m-tall tower located abou t 15 km southeast of Raleigh, NC, as part of an effort by the state of Nort h Carolina to develop a state implementation plan (SIP) for ozone control i n the Raleigh Metropolitan Statistical Area. During summer 1993, 1994, and 1995, ozone was monitored at ground level, 250 m, and 433 m. Boundary layer wind, temperature, and other meteorological variable profiles were determi ned from balloon soundings. During summer 1996 and 1997, ozone was monitore d at ground level, 76 m, 128 m, and 433 m.
