Characteristics of ozone in the Baltimore-Washington area: 1-hour average concentrations
Technical Report
·
OSTI ID:675947
The purpose of this study was develop a 15-year climatology (1981-1995) for the 1-hour diurnal maximum ozone concentration (DMOC) at the surface for the Baltimore-Washington area. The area was divided into four regions: Baltimore, Washington, non-urban Maryland, and non-urban northern Virginia. In each area, the time series of the DMOC were divided into four terms representing different behavioral time scales: the long-term mean; the mean intra-annual perturbation, the interannual perturbation; and the synoptic perturbation. Histogram of the zone exceedance were created by month and by concentration. Non-meteorological trend for ozone over the fifteen year period were developed for Washington and Baltimore. A linear model was used to determine the meteorological trends and remove these trends from the data to obtain the non-meteorological trends. The report discusses various problems with obtaining a satisfactory measure of the non-meteorological trend.
