| The depth of the ozone hole is the lowest ozone column value in Dobson Units (DU) for latitudes below 30° South. | The size of the ozone hole is the area on the globe in million square km of ozone column values below 220 DU. | The ozone loss is the amount of ozone in megaton necessary to fill the ozone hole to 220 DU over the whole area |
