    History of Ozone: Introducing Ozone for Health. Among the first uses in the history of ozone was the disinfection of water. Today more than cities throughout the world use ozone in the water purification process. These cities include Los Angeles, Montreal, Moscow, Kiev, Paris, Amsterdam, Singapore, and Florence to name a few.   The ‘smoking gun’ is the opposite ozone response to solar variations below and above 45km and above the poles as compared to above the equator. As I have been saying since it has to be the way I describe it in order to achieve the correct sign of jet stream shifting. 14 Regional and Seasonal Variation (Ozone layer) Since solar radiation makes ozone, one expects to see the thickness of the ozone layer vary during the year. This is so, although the details do not depend simply upon the amount of solar radiation received at a given latitude and season - one must also take atmospheric motions into account.

Weather and climate are experienced in the troposphere, which extends upward to the tropopause at about 15 km. The Earth's middle atmosphere (the stratosphere and the mesosphere) extends from the tropopause to approximately 90 km (Figure ).

Ozone production in the upper atmosphere is dependent on the amount of energy coming from the sun. During peaks of solar activity, ozone is created at a greater rate. During lulls in the sunspot cycle, the ozone Ozone variations of solar origin book is thinner.

The lowest level ever measured was in At night, on the dark side of the planet, the ozone layer disappears, in. Various external factors of solar origin like solar activity (solar cycle, day variation etc.), geomagnetic storms and other solar wind-related phenomena, and changes of fluxes of high-energy particles can potentially affect the ozone layer.

The diurnal variation of ozone depletion increases with increasing altitude because of increasing dependency on the HO x reactions and faster daytime production of O x.

At 50 km the variation is not significant while at 70 km the magnitude of the depletion can differ within a day by several tens percent, depending on the local time considered.

Past and current research efforts at IZMIRAN (the Soviet Institute for the Study of Terrestrial Magnetism, the Ionosphere, and the Propagation of Radio Waves) on galactic and solar cosmic rays is reviewed.

Particular attention is given to investigations of penumbra effects manifested in cosmic rays, long-term cosmic-ray variations, cosmic-ray anisotropy, cosmic-ray fluctuations, the possible. Regarding the daily cycle of the surface ozone in the study area, this evolution follows fairly the corresponding solar radiation variations, although modulated by precursor emissions, chemical and physical processes, and meteorological conditions (Adame et al.

Consequently, seasonal differences in these factors modulate the daily. Ozone depletion consists of two related events observed since the late s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions.

The latter phenomenon is referred to as the ozone are also springtime polar tropospheric ozone depletion. Also forgotten is a long list of truly ridiculous claims, such as the one from Al Gore's book "Earth in the Balance"that, thanks to the Antarctic ozone hole, "hunters now report finding blind.

For instance, Charles Jackman of the Goddard Space Flight Center described how nitrogen oxides (NOx) created by solar energetic particles and cosmic rays in the stratosphere could reduce ozone levels by a few percent.

Because ozone absorbs UV radiation, less ozone means that more UV rays from the sun would reach Earth's surface.

History. In Dutch chemist Paul Crutzen published a paper that described the major nitrogen oxide catalytic cycle affecting ozone levels.

Crutzen demonstrated that nitrogen oxides can react with free oxygen atoms, thus slowing the creation of ozone (O 3), and can also decompose ozone into nitrogen dioxide (NO 2) and oxygen gas (O 2).Some scientists and environmentalists in the s used.

This contribution of ozone and its precursors from these source areas result in a fast ozone rise in the early morning on these days. In addition, right at the alleged ozone hole is a HUGE source of natural chlorine: Mt.

Ozone's Janus Face: Ground-Level Ozone Presents One of the Most Complex Air-Quality Issues Facing the Nation Today By Meagher, James F Forum for Applied Research and Public Policy, Vol. 16, No. 3. The objective of this paper is to review the origin, causes, mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer.

The chlorofluorocarbon. Ozone Depletion Theory False. New scientific evidence continues to demonstrate that the ozone depletion models -and the resulting ban on CFCs- are based on a Big Lie. By Rogelio Maduro Co-author of the book "The Holes in the Ozone Scare", The ozone layer is well observed since the s from the ground and, since the s, by satellite-based instruments.

The evolution of ozone in the past is important because of its dramatic influence on the biosphere and humans but has not been known for most of the time, except for some measurements of near-surface ozone since the end of the 19th century. This gap can be filled by either.

The confounding of many influences over the last decade including the increase in chlorine, the injection of volcanic sulfur, year-to-year variations in the dynamics of the stratosphere, and also possibly the year solar sunspot cycle, make the determination of trends in ozone an interesting and difficult problem.

Solar Variability, Ozone, and Climate. People have thought for a long time that a major natural source of climate change are variations in solar output. For instance, these may have been responsible for episodes such as the Little Ice Age during the 15th to 18th centuries.

As surface temperatures have risen rapidly during recent decades, as. The ozone response to solar variations with a day period was used to estimate the year solar cycle amplitude in tropical ozone.

Biases in individual SBUV instrument data were included as a. Ozone is Earth's natural sunscreen, shielding life from excessive amounts of ultraviolet radiation. But Earth's ozone layer has been damaged by well-intentioned chemicals—chlorofluorocarbons, used for refrigerants and aerosol spray-cans—that have the unintended consequence of destroying ozone.

According to Figure 3, O 3 mixing ratio increases monotonically from early morning, reaching its maximum value of 34 ppbv (sample mean) at ~4 p.m. LT The diurnal variations of NOx, CO, and benzene, the latter being an important ozone precursor with anthropogenic origin, are opposite to that of O 3 and characterized by a stable decrease from.

A new study confirms a long-held theory that large solar storms rain electrically charged particles down on Earth's atmosphere and deplete the upper-level ozone for weeks to months thereafter.

New evidence from NASA and NOAA satellites is helping scientists better understand how man and nature both play a role in ozone loss. the stratosphere is due to the ozone absorption of ultraviolet solar energy.

Although maximum ozone concentration occurs at 25km, the lower air density at 50km allows solar energy to heat up temperature there at a much greater degree. Also, much solar energy is absorbed in the upper stratosphere and can not reach the level of ozone maximum.

The temporal and spatial variations of NO, NO 2, and O 3 concentrations in Seoul, South Korea, during the solar eclipse of 22 July are investigated by analyzing data measured at 25 environmental monitoring stations.

The NO 2 concentration increases and the NO and O 3 concentrations decrease because the efficiency of NO 2 photolysis decreases during the solar eclipse. The ozone variation between the extremes of the Sun's activity is so great that it is likely to impact the temperature balance of the atmosphere.

These temperature changes can in turn have an. Near the top of the stratosphere is a layer of ozone (O 3), a heavy form of oxygen with three atoms per molecule instead of the usual e ozone is a good absorber of ultraviolet light, it protects the surface from some of the Sun’s dangerous ultraviolet radiation, making.

The small part of this energy intercepted by Earth (the solar constant, on average. The discovery that CFCs deplete ozone was first announced inwhen the ozone layer was still relatively robust.

Between andseveral papers suggested possible mechanisms for the ozone hole, including chemical, dynamical (meteorological), and solar cycle influences. Among the key papers explaining the atmospheric chemistry of CFCs and ozone depletion was one by Susan Solomon and several colleagues.

the sun is the prime source of almost all energy on the earth. This energy coming from the sun is known as solar the sun is extremely hot, it emits shortwave radiation in the form of electromagnetic waves.

different types of shortwaves like x-rays, ultraviolet, visible and near infrared. the shortwave energy from the sun is not directly absorbed by the atmosphere. RSTV: IN DEPTH- THE OZONE LAYER Introduction: September 16th every year is marked as the International Day for the Preservation of the Ozone Layer.

On this day 32 years ago, 45 countries signed a treaty to phase out the use of the substances that harm or deplete the ozone layer, however all countries Continue reading "RSTV: IN DEPTH- THE OZONE LAYER".

Scientists have found that ozone levels change periodically with regular natural cycles such as the changing seasons, winds, and long time scale sun variations. Ozone also responds to some sporadic. solar events such as flares. Moreover, volcanic eruptions may inject materials into the stratosphere that can lead to increased destruction of ozone.

Natural variations in the solar W output may have influenced stratospheric ozone during the recent past when Dobson instruments and satellite instruments have measured ozone. While there is no argument in principle that W irradiance changes would modulate ozone amounts, there is disagreement over the reality of solar cycle variations in W.

This caused a number of pilot projects to take place, during which the disinfection mechanism of ozone was researched. The French chemist Marius Paul Otto (figure 1) received a doctorate at the French University, for his essay on ozone.

Solar radiation enters the atmosphere. About 18 percent of the incoming shortwave radiation is absorbed by ozone near the top of the stratosphere and in the troposphere by clouds, water vapor, and aerosols. Absorption by oxygen (O2) and ozone (O3) produces the ozone layer by the reactions: M is a molecule of any substance, but usually nitrogen.
