Lecture 35. Stratospheric Ozone Chemistry. 1. the Formation of Ozone
Lecture 35. Stratospheric ozone chemistry. Part 1. Formation and destruction of stratospheric ozone. Objectives: 1. The formation of ozone: Chapman mechanism. 2. Catalytic ozone destruction. 3. Ozone and UV radiation. Readings: Turco: p. 407-414; Brimblecombe: 190-194. 1. The formation of ozone: Chapman mechanism. “Bad ozone”: in photochemical smog -> health threat in the troposphere -> contributes to global warming “Good ozone”: in the stratosphere -> absorbs biologically harmful UV radiation emitted by sun. Most of the Earth’s atmosphere ozone (about 90%) is found in the stratosphere. Typical ozone concentrations: in very clean troposphere: 10 – 40 ppb; in ozone layer at 25-30 km: about 10 ppm; • The ozone column abundance is typically specified in Dobson units. One Dobson unit, DU, is the thickness that the ozone column would occupy at standard temperature and pressure (T =273.2 K, P = 1 atm): 1 DU = 10-3 atm cm =2.69x1016 molecules cm-2 Total column ozone values range from about 290 to 310 DU over the globe. 1 In 1930 S.Chapman, a British scientist, proposed a theory of the formation of ozone in the stratosphere (known as Chapman mechanism): Major steps of Chapman mechanism: 1) Above about 30 km altitude, molecular oxygen absorbs solar radiation (wavelength < 242 nm) and photodissociates: O2 + hν -> O + O 2) The oxygen atom, O, reacts rapidly with O2 in the presence of a third body, denoted M (M is usually another O2 or N2), to form ozone: O2 + O + M -> O3 + M NOTE: above reaction is the only reaction that produces ozone in the atmosphere!!! 3) Ozone absorbs solar radiation (in the wavelength range of 240 to 320 nm) and decomposes back to O2 and O: O3 + hν -> O2 + O 4) Additionally, ozone can react with atomic oxygen to regenerate two molecules of O2: O3 + O -> O2 + O2 2 Let’s consider the dynamic behavior of reactions (1) –(4). -

On the other hand the Weather is what is happening in one small region at one time. The global climate always changes, and there are many reasons for that, such as the interactions between components in the climate system like oceans, atmosphere, etc. The cyclone Aila was actually a climatic phenomenon, where the change in surface temperature over the Indian ocean formed the tropical cyclone Aila over the Bay of Bengal on May 23, 2009, causing extensive damage in India and Bangladesh. The climate change occurs because when the amount of energy in the entire climate system is changed it affects each and every component in the system. We the humans are also responsible for the climate change. Human activities like the burning of fossil fuel increases the amount of carbon dioxide (CO 2) and other greenhouse gases in the atmosphere, enhancing the natural greenhouse effect. Increasing CO 2 causes the planet to heat up. The concentration of atmospheric CO 2 has increased by at least 40% in the last 200 years. The last time CO 2 increased this much was over a period of 6000 years, when the earth came out of an ice age, and the average surface temperature rose by 5 oC. Burning fossil fuels, changes in land use (such as deforestation), small particles like smoke and dust in the atmosphere (aerosols) have altered the amount of sunlight that can reflected back into space. -

Q11: How Severe Is the Depletion of the Antarctic Ozone Layer? Antarctic
TWENTY QUESTIONS: 2006 UPDATE III. STRATOSPHERIC OZONE DEPLETION Q11: How severe is the depletion of the Antarctic ozone layer? Severe depletion of the Antarctic ozone layer was first observed in the early 1980s. Antarctic ozone depletion is seasonal, occurring primarily in late winter and early spring (August-November). Peak depletion occurs in early October when ozone is often completely destroyed over a range of altitudes, reducing overhead total ozone by as much as two-thirds at some locations. This severe depletion creates the “ozone hole” in images of Antarctic total ozone made from space. In most years the maximum area of the ozone hole far exceeds the size of the Antarctic continent. The severe depletion of Antarctic ozone, known as values occur in ozone hole images, balloon measurements the “ozone hole,” was first observed in the early 1980s. show that the chemical destruction of ozone is complete The depletion is attributable to chemical destruction by over a vertical region of several kilometers.

The severity of Antarctic ozone deple- tion can be seen using satellite observations of total ozone, ozone altitude profiles, and long-term average values of polar total ozone. -

Section III: STRATOSPHERIC OZONE DEPLETION Q11 How severe is the depletion of the Antarctic ozone layer? Severe depletion of the Antarctic ozone layer was first reported in the mid-1980s. Antarctic ozone depletion is seasonal, occurring primarily in late winter and early spring (August–November). Peak depletion occurs in early October when ozone is often completely destroyed over a range of altitudes, thereby reducing total ozone by as much as two-thirds at some locations. This severe depletion creates the “ozone hole” apparent in images of Antarctic total ozone made using satellite observations. In most years the maximum area of the ozone hole far exceeds the size of the Antarctic continent. he severe depletion of Antarctic ozone, known as the can be seen using satellite observations of total ozone, ozone T“ozone hole,” was first reported in the mid-1980s. The altitude profiles, and long-term changes in total ozone. depletion is attributable to chemical destruction by reactive Antarctic ozone hole. The most widely used images of halogen gases that increased in the stratosphere in the latter Antarctic ozone depletion are derived from measurements of half of the 20th century (see Q16). Conditions in the Antarctic total ozone made with satellite instruments. A map of Ant- winter and early spring stratosphere are highly suitable for arctic early spring measurements shows a large region centered ozone depletion because of (1) the long periods of extremely near the South Pole in which total ozone is highly depleted (see low temperatures, which cause polar stratospheric clouds Figure Q11-1). This region has come to be called the “ozone (PSCs) to form; (2) the large abundance of reactive halogen hole” because of the near-circular contours of low ozone values gases produced in reactions on PSCs; and (3) the isolation of in the maps.
