Ozone in the Atmosphere

Abbasi, S. A.; Abbasi, Tasneem

Pages: 1 –12

[Environmental pollution has been occurring with increasing intensity and geographic spread ever since the humankind discovered fire about 300,000 years ago [1]. But environmental pollution began to attract popular attention on a global scale only since the lower half of the previous century...

The Ozone Hole

Abbasi, S. A.; Abbasi, Tasneem

Pages: 13 –35

[In popular perception ‘ozone hole’ is something similar to a hole in a cloth wherein the hole represents a total absence of the surrounding material. But ‘ozone hole’ doesn’t represent a region of zero ozone concentration in the atmosphere. Rather it represents a region of atmosphere where there...

Factors Accelerating Ozone Depletion

Abbasi, S. A.; Abbasi, Tasneem

Pages: 37 –50

[Just as carbon dioxide is inexorably associated with global warming, chlorofluorocarbons (CFCs) are implicated in ozone hole. But CFCs are not the only ozone-destroying chemicals in the environment; there are three other classes of substances as well (Fig. 3.1).]

Impacts of Ozone Hole

Abbasi, S. A.; Abbasi, Tasneem

Pages: 51 –99

[Due to the decrease in the quantity of total-column ozone in the stratosphere—which we call ozone hole—lesser solar UV-B radiation (290–320 nm) is absorbed, resulting in greater fluxes of it reaching the earth’s surface. As the UV-B radiation is the most energetic component of sunlight that...

The Global Ozone-Depletion Trends

Abbasi, S. A.; Abbasi, Tasneem

Pages: 101 –111

[Figure 5.1 illustrates how the Antarctic ozone hole has been initially shaped and how it then expanded quickly. Figures 5.2 and 5.3 depict typical holes (as on October 4, 2004, and September 17, 2009). How ozone profiles have changed over Antarctic and Arctic from the time there was no ozone...

Strategies to Contain the Ozone Hole

Abbasi, S. A.; Abbasi, Tasneem

Pages: 113 –120

[The Vienna Convention for the Protection of the Ozone Layer was established in 1985, under the United Nations Environment Programme (UNEP). It had happened very soon after the first experimental evidence had come of the veracity of the ozone hole theory of Rowland and Molina. The evidence was...

Monitoring Ozone Loss and Its Consequences: Past, Present, and Future

Abbasi, S. A.; Abbasi, Tasneem

Pages: 121 –131

[Two major changes observed in atmospheric ozone from 1980 onwards are (1) the strong downward trend of spring time Antarctic ozone since 1980 and (2) the widespread decrease in total ozone in subtropical and middle latitudes since 1982, associated with the eruptions of EL Chichon in March–April...
