In this study, the multivariate linear regression was described by the hourly frequency distributions of continuous measurements using meteorological variables and ozone levels. The ambient O-3 concentration of was monitored continuously in the town of Kurupelit, Samsun, Turkey for one year (2005-2006). The meteorological variables were temperature, relative humidity, wind speed, solar radiation, and ambient pressure. A negative association was observed between O-3 and temperature a weak relationship (r(2)=0,289), and between O-3 and solar radiation a weak relationship (r(2)=0,102). The data from the continuous monitoring of O-3 shows a negative correlation with relative humidity and atmospheric pressure. Keywords: Ambient air, meteorology, tropospheric ozone.
