Blozone Hole
A New Theory on the Ozone Hole

Atmospheric Gases

The ozone hole is increasing/stabilizing but the relative amount of ozone is increasing:

What is the ozone holeThe ozone hole (Blozone Hole ) is not technically a hole, but is a region of ozone that is below 220 Dobson units which normally occur  at the beginning of Southern Hemisphere spring (August–Novemberr). NASA satellite instruments provide us with daily images of ozone over the Antarctic region, the hole itself changes its with the weather associated with the stratosphere. The polar vortex plays an important part of the ozone holes shape. The ozone hole image above shows the very low values (blue and purple colored area) centered over Antarctica on December 14, 2015. From the historical record we know that total column ozone values of less than 220 Dobson Units were not observed prior to 1979.
