Measurements by GOME-2: Ozone Hole over the south polar region from 1 to 3 October 2010
Measurements by GOME-2 (Global Ozone Monitoring Experiment), an atmospheric sensor on board the EUMETSAT MetOp-A satellite, make it possible to determine the thickness of the Ozone Layer, that is, the total amount of ozone in the atmosphere [in dobson units; DU]. This image shows the Ozone Hole over the south polar region from 1 to 3 October 2010, with ozone figures substantially below 150 dobson units. The Ozone Hole extends across most of Antarctica.
