Ozone Pollution Map Interpreting the Ozone Map Ozone Monitoring Ozone data are collected by state and local agencies operating over 200 air monitoring stations on the ozone map region. These regions follow methods established by the Environmental Protection Agency, and routinely check their monitors for accuracy and reliability. Ozone values are hourly averages computed from readings taken every several seconds. Depending upon the measuring agency's equipment, data are usually available between 10 and 20 minutes after the top of the hour. Not all ozone sites have the same geographic coverage: some sites, especially those influenced by ocean or bay breezes, only represent the immediate vicinity, while other more 'regional' sites are representative of 10's of miles. Ozone data represent point measurements, and regardless of how well the monitor is sited, ozone may exhibit erratic behavior that may be observed in the ozone map. This is the function of micro-scale effects being interpolated over a larger area. Ozone Meteorology Ozone forms from a combination of volatile organic compounds (aka VOC's, which come primarily from vehicle exhaust, solvents, and other vapors), nitrogen oxides (aka NOx, which is emitted by power plants, vehicles, and other combustion sources), and sunlight.

Midwestern Smog Pushes Ozone to Limit Pollutants Wafting East Trip D.C. Area Sensors PETER WHORISKEY / Washington Post 10aug03 One tranquil night in June, the air pollution monitors at Shenandoah National Park registered a swift and curious spike in smog, and the trouble wasn't coming from the sanctuary's abundant trees and wildlife. The pollutants were blowing in from the Midwest, wafting toward the East Coast and along the way tripping air-quality monitors in pristine refuges and threatening worse concentrations in cities. For the Washington area, it was the start of the worst stretch of ozone pollution this summer. Between June 24 and June 26, when air-quality regulators tracked the movement of a mass of ozone-laden air across the eastern United States, smog monitors from Annandale to western Prince George's County recorded levels in excess of federal health limits. "We got a lot of bad air from the Ohio River Valley," said Charles Piety, a University of Maryland meteorologist who studies these flows for the state. "It was our standard high-ozone meteorology." Although the Washington area's infamous traffic and the popularity of SUVs often are blamed for the region's smog problems, which were classified as "severe" by federal officials this year, a significant source of the area's pollution lies beyond local control. Some scientists say that half and sometimes more of the offending ozone is from out of town. And as the pollution monitors at Shenandoah show, it's arriving in concentrations high enough to violate federal health limits even without a boost from local emissions.

Office of Air Quality Address/Phone/Fax aqp@tnrcc.state.tx.us Help ... Search February 25, 1998 Meteorology Data and Activity Background: Ground-level ozone pollution is mainly a daytime problem during summer months because sunlight plays a primary role in its formation. Nitrogen oxides and hydrocarbons are known as the chief "precursors" of ozone. These compounds react in the presence of sunlight to produce ozone. The sources of these precursor pollutants include cars, trucks, power plants and factories, or wherever natural gas, gasoline, diesel fuel, kerosene, and oil are combusted. These gaseous compounds mix like a thin soup in the atmosphere, and when they interact with sunlight, ozone is formed. Large industrial areas and cities with heavy summer traffic are the main contributors to ozone formation. When temperatures are high and the mixing of air currents is limited, ozone can accumulate to unhealthful levels. The United States Environmental Protection Agency has set the National Ambient Air Quality Standard for ozone at 0.12 parts per million (ppm). Ozone concentrations of 0.125 ppm (125 in parts per billion) or above are considered an exceedance of this standard because of mathematical rounding. The Monitoring Operations Division has more ozone information.

Weather: National Victoria NSW ACT ... Climate Glossary Ozone is one of the several gases that make up the earth's atmosphere. It is the triatomic form of oxygen and makes up approximately one part in three million of all of the gases in the atmosphere. If all the ozone contained in the atmosphere from the ground level up to a height of 60 km could be assembled at the earth's surface, it would comprise a layer of gas only about 3 millimetres thick, and weigh some 3000 million tonnes. Ozone is toxic at high concentrations because it reacts strongly with other molecules. Frequently Asked Questions: Where is ozone found? Why is ozone important? How is ozone measured? What is a Dobson unit? ... How long have we been measuring the ozone hole? Where is Ozone found? About 90% of ozone is concentrated between 15 and 30 kilometres above the earth's surface (stratospheric ozone). It is also found at ground level in lower concentrations where it is a key component of smog over major cities (tropospheric ozone). Why is ozone important? Ozone is the major absorber of UVB (Ultraviolet radiation in the wavelength range 280-320 nanometres) in sunlight, absorbing approximately 90% of it. Many experimental studies of plants and animals, and clinical studies of humans have shown the harmful effect of excessive exposure to UVB radiation.

14. Gardner An Investigation into the Importance of meteorology in Determining Surface ozone Concentrations a Neural Network Approach. Matthew W. Gardner out looking at the relationship between meteorology http://www.geocomputation.org/1996/abs037.htm

An Investigation into the Importance of Meteorology in Determining Surface Ozone Concentrations - a Neural Network Approach Matthew W. Gardner School of Environmental Science, University of East Anglia, Norwich, Norfolk NR4 7TJ, United Kingdom Abstract Surface ozone concentrations are determined by a complex interaction between radiative chemical and meteorological processes. Ozone is classified as a secondary pollutant since it is not released directly into the atmosphere, but is photochemically produced in the presence of its precursors and sunlight. Ozone concentrations are strongly linked to the meteorological conditions in the boundary layer and also to long-range transport of both ozone and its precursors. Land-sea breezes also influence ozone concentrations at coastal sites. To date there exists a discrepancy between the timescale with which ozone chemistry is known to operate and the study of the meteorology-ozone relationship. Ozone chemistry is measured and modelled on timescales of minutes to hours whereas the majority of work investigating the effect of meteorology on surface ozone concentrations has been undertaken on timescales of days to years. The objective of this research was to investigate the effect of local meteorology on surface ozone concentrations on an hourly basis for a period of at least one year. A feed-forward back propagation neural network was developed to model hourly ozone concentrations from simple meteorological data. The data are from Weybourne, a coastal site in North Norfolk; and include hourly observations of temperature, humidity, irradiance, wind speed, direction and ozone concentrations for the whole year of 1994. No chemical data was used as input to the model. By using purely meteorological input data the degree of ozone concentration variability resulting from changes in weather conditions could be assessed. Any remaining variability could then be attributed to other causes such as the chemical interaction between hydrocarbons and the oxides of nitrogen. Previous work by Boznar et al. (1992) has already illustrated the successful use of a neural network to predict SO

The dependence of monitored ozone levels on meteorology and nitrogen oxide concentrations in SW Indiana and NW Kentucky Joanne M. Alexandrovich Ozone Officer, Vanderburgh County Health Department, 1 NW M.L. King Jr. Blvd, Evansville, IN 47708 o3office@evansville.net ABSTRACT , and NO x ) and meteorological variables (wind direction and speed, temperature, humidity, pressure, and solar radiation) were examined. Several identifiable weather patterns were found to produce ozone events (high monitored maximum ozone levels lasting one or two days), and ozone episodes (high monitored maximum ozone levels lasting three days or more). However, no other clearly limiting condition to ozone formation was identified although NOx, temperature, humidity and solar radiation vary predictably with ozone variations. Locally, ozone dissociation by NO emitted from mobile sources is an important factor mitigating high ozone levels. INTRODUCTION The City of Evansville, located on the Ohio River in Vanderburgh County Indiana, is the urban hub of southwestern Indiana. The Evansville Metropolitan Statistical Area (MSA), which also includes the City and County of Henderson Kentucky, and the Indiana counties of Posey and Warrick, is home to approximately 300,000 people. Around the main cities of Evansville and Henderson, one finds manufacturing industries and suburban developments dispersed among agricultural lands. Vanderburgh County was designated as a marginal ozone nonattainment area in 1992 In recent years, area ozone monitors have recorded several exceedances but no violations of the one-hour ozone standard, however, as of 1999, seven out of the area eight area monitors have recorded violations of the new eight-hour standard.

20. Meteorology Of Ozones meteorology of ozone The troposphere and the stratosphere are the two lowest layersof the atmosphere. The troposphere is the layer next to Earth s surface. http://www.cotf.edu/ete/modules/ozone/ozatmo4.html

Skip Navigation Meteorology of Ozone The troposphere and the stratosphere are the two lowest layers of the atmosphere. The troposphere is the layer next to Earth's surface. On the average, it extends 11 km to the top of the troposphere which is called the tropopause. In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere's gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection . Since this heating is most effective near the ground, the temperature in the troposphere gradually decreases with increasing altitude until the tropopause is reached. This is the beginning of the stratosphere. In the stratosphere, the temperature remains isothermal until about 20 km. Then a strange thing happensthe temperature actually begins to increase with altitude. From a temperature of about -56.5C at 20 km, it increases to -2.5C at 50 km. The reason for this temperature fluctuation is that ozone absorbs the uvb radiation in the lower atmosphere. Higher in the atmosphere, however, normal diatomic oxygen absorbs the uvc radiation. Once it is absorbed, it is reradiated at different wavelengths, thereby warming the stratosphere. At the top of the stratosphere (about 50 km, the stratopause), the temperature begins to decrease again as the altitude increases. Above the stratopause, in the mesosphere, thermosphere, and exosphere harmful gamma rays and X-rays are absorbed.
