The spatial and temporal distributions of ozone in the eastern two-thirds of the . I present the results of an analysis of ozone data from rural locations in the United States.

The spatial and temporal distributions of ozone in the eastern two-thirds of the . during three typical ozone episodes that occurred in July 1978 are examined. In all three cases, a distinct area of high ozone concentrations was observed flowing northeastward in an aerial ''''river'' extending from the southwest Gulf Coast to New England. Ozone concentration above 80 ppb are common in the east in spring and summer, but they are unusual in the west, and ozone shows considerably more day-to-day variability in the east.

Heat and Cold ResistanceSince silicone rubber has high bond energy and good chemical stability, its heat resistance is better than that of organic polymers. Furthermore, since the intermolecular interaction force is weak, the glass transition temperature is low and the cold resistance is also good. Therefore, its properties will not change when used in any part of the globe.

Our SAOD climatology represents a significant improvement over satellite-based analyses, which ignore aerosol extinction below 15 km, a region that can contain the vast majority of stratospheric aerosol extinction at mid- and high-latitudes.

Ground-level ozone is adverse to human and vegetation health. High ground-level ozone concentrations usually occur over the United States in the summer, often referred to as the ozone season. However, observed monthly mean ozone concentrations in the southeastern United States were higher in October than July in 2010. The October ozone average in 2010 reached that of July in the past three decades (1980–2010).

Ozone (/ˈoʊzoʊn/), or trioxygen, is an inorganic molecule with the chemical formula O3. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O2, breaking down in the lower atmosphere to O2 (dioxygen). Ozone is formed from dioxygen by the action of ultraviolet light (UV) and electrical discharges within the Earth's atmosphere.

This is a AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A207813. The abstract provided by the Pentagon follows: A statistical anlysis of ozone (O3) concentrations and meterorogical parameters was performed to determine the effect of meteorological changes on ambient O3 concentrations in the urban and semi-urban environment on a regional basis in the Southeast United Stated. The correlation between average daily maximum O3 concentration and various meteorological varibles was analyzed on a monthly basis from April through October 1980-1994. Positive correlation was found between O3 concentration and temperature and dewpoint temperature depression, while negative correlation was found between O3 concentration and relative humidity and the minimum Pasquill Stability Index. The correlations were strongest during the summer months, particularly June, July, and August. High pressure stagnation was found to be positively correlated with O3 concentrations, although not at a statistically significant level. Regional analysis indicates that the location of areas of high pressure stagnation may play an important role in the resultant ambient concentrations of O3 throughout the region. Analysis of long term O3 concentration trends indicates increasing trends during the 1980s and decreasing trends during the 1990s. Trends for meteorological parameters that demonstrate positive (negative) correlation with O3 increase(decrease) during the 1980s, however causal relationship between these trends and those for O3 cannot be determined based on this analysis. A regional model was developed to forecast ozone concentration based on the previous day's ozone concentration and meteorological parameters.
