Study of Spatial Distribution of Ozone and Its Correlation with Meteorological Parameters and Precursors
Abstract
Temporal analysis was performed to study ozone exceedance patterns and geostatistical analysis was performed to study diurnal variation of ozone in Oklahoma and specifically for a site in Skiatook. The effect of temperature, relative humidity, wind speed, solar radiation and pressure on ozone concentrations was also studied. Multi-linear regression analysis was performed to forecast next day 1-hr ozone, 8-hr ozone, and daily maximum 1-hr ozone in Skiatook. The data from 10:00 a.m. to 5:00 p.m. for the months of May to September from 1998 - 2000 was used for the analysis. The forecasted values obtained from these models were tested to be within 0.005 ppm of the actual ozone values. Temperature was the only meteorological parameter found to have noticeable effect on high ozone concentrations. It was found that using the previous day ozone concentration as a predictor helped achieve a higher R2 value for ozone forecast.
