The total ozone columns, derived in near-real time from observations by the satellite instrument GOME-2 (and SCIAMACHY in past), are used as an input for a data assimilation program which provides global ozone fields for today and a forecast for the coming days.

The depth of the ozone hole is the lowest ozone column value in Dobson Units (DU) for latitudes above 30° North. |
|
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 |
