Korea Meteorological Administration (KMA) started ozone layer research and monitoring at the Pohang weather station (36 degrees 02' N, 129 degrees 23' E, 1.9 m MSL) as one of the WMO/GO(3)OS (World Meteorological Organization/Global Ozone Observing System #332) in March 1994. Thereafter, daily measurements of the total ozone amount and a weekly measurement of vertical ozone distribution have been made using the Brewer ozone spectrophotometer and ozonesonde. The vertical distributions of ozone using ozonesondes for Pohang show an annual maximum density in the layer between 18 km and 26 km, while monthly maximums of 15 mPa in the layer about 20 km in February and 13 mPa at about 24 km in August are observed, respectively. Seasonal mean variations of the daily total ozone amount have a maximum value in springtime and a minimum value in autumn. The seasonal mean values for the total ozone amount of spring, summer, autumn and winter are 340.7 DU, 301.7 DU, 283.4 DU and 321.3 DU, respectively, and the 11-year (1994-2005) mean total ozone amount is 313.5 DU.
