normal amount of overhead ozone is about 300 - 400 du in temperature latitudes (about 3 mm, 0. 3 cm: amount of ozone over polar regions is usually higher than temperate regions which in turn is greater than over the tropics. Characteristics of the ozone hole: very-low overhead ozone occurs over the south pole where levels usually are highest, happens in sept - oct, which is early spring in antarctica; this is the season when max polar. [ozone] normally occurs: hole heals by summer, has occurred annually since about 1979.
