Dr. John Nielsen-Gammon Observations and Simulations of Houston Ozone Meteorology A BSTRACT The Texas 2000 Air Quality Study was the first major field study of Houston's major ozone problem. Any understanding of urban air pollution requires detailed knowledge of the three-dimensional wind field, and TexAQS-2000 included six wind profilers, a Doppler lidar, three radiosonde launch sites, and four instrumented aircraft in addition to conventional surface observations and an air quality mesonetwork. According to the observations, the dominant wind pattern in the Houston area is a steady rotation of the wind associated with a large-scale sea breeze response to coastal forcing. Houston's proximity to 30 N, where the inertial and diurnal frequencies are equal, appears to lead to forced inertia-gravity waves of particularly large amplitude and large horizontal scale. The wind variations can be conceptualized as a circular wind progression superimposed on a steady background wind. This simple model accounts for the trajectory patterns observed on high ozone days during TexAQS-2000 and appears to explain the location, timing, and likelihood of the majority of high ozone events.

Contact Us About MDE Site Index Work with MDE ... 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. The increased incident solar radiation during the summertime as well as more 'stagnant'

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

7. 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

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.

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.

Weather: National Victoria NSW ACT ... Tasmania FORECASTS FOR SUN SAFETY Predictions of ultraviolet radiation help the campaign against skin cancer This year, almost 300,000 Australians will visit a doctor or specialist to have a skin cancer (or cancers) removed. Sunburn caused by overexposure to ultraviolet-B (UVB) radiation is known to be the primary cause of skin cancer. To help people choose appropriate levels of protection against skin cancer, the Bureau of Meteorology issues daily forecasts of the UV Index. UV Index forecasts are issued as a map of Australia, a numerical value with descriptive category, and as a graph, for capital cities and towns across Australia. The map, text and graphical forecasts are available via the Bureau's website. The mass media also receive text forecasts along with other Bureau services. Commencing December 2002, the Bureau of Meteorology, Cancer Council Australia and Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) adopted the World Health Organisation Global Solar UV Index, for reporting the level of solar UV danger in Australia. The progressive adoption of the Global UV Index by other countries will heighten the awareness of the sun safety message for tourists and residents alike. About ultraviolet radiation The sun emits three types of ultraviolet radiation – UVA, UVB and UVC. UVA penetrates deep into the skin causing damage like wrinkles and discolouration. Exposure to UVB causes sunburn, a skin reaction where blood vessels expand and leak fluids, producing inflammation, pain and redness. Sunburn, whether severe or mild, can cause permanent and irreversible skin damage. Cumulative exposure to UV radiation and the number of severe sunburns received, especially during childhood, increases the risk of developing skin cancer.

How does meteorology/weather influence ozone concentrations? The chemical reaction required to form tropospheric ozone occurs most efficiently on hot, sunny days under stagnant and humid air conditions. High humidity and high temperatures enhance the formation of ozone. Low wind speeds lead to the buildup of high local pollutant concentrations. High winds tend to dilute ozone concentrations locally near sources but they also transport ozone to other locations, often causing high ozone concentrations in areas without large sources of NOx and VOCs.
