, 2004 The ozone hole is a recent seasonal phenomenon which corresponds to a significant reduction in the total amount of ozone in the EARTH'S ATMOSPHERE during springtime over Antarctica. Evidence that this phenomenon is caused by human activities through the release into the atmosphere of man-made chlorine and bromine compounds has been building up over the

Global ozone depletion and the Antarctic ozone hole
Journal of Geophysical Research: Atmospheres, 1992The secular trend of the Antarctic ozone hole has been studied with a two‐dimensional model which can simulate formation of polar stratospheric clouds and includes heterogeneous chemical reactions. Results from the numerical simulation have been validated by comparison with available experimental data.

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 is a significant degree of decrease in the concentration ...

Is there an Ozone hole in the Tropics?
2023Amount of ozone in the stratosphere is very small as compared to other trace gases in the atmosphere. Yet, significant changes in its concentrations have great consequences in the environment and ecosystems. However, such drastic changes in ozone happens only in the high and middle latitudes, particularly in the polar spring, where chemical ozone loss ...

CFCs and the Size of the Ozone Hole
Science, 2006The Netwatch item “Ozone tracker” (9 June, p. [1447][1]) furthers the common misconception that the size of the Antarctic ozone hole is a function of ozone-destroying chlorofluorocarbons (CFCs). The column amount of ozone within the hole (its depth) may be controlled, in part, by inorganic chlorine derived from the breakup of CFCs, but the area ...
