Monitoring the Antarctic Ozone Hole featuring:

METOP-A/GOME-2 and ENVISAT/SCIAMACHY

Please notice, ENVISAT instruments are currently not sending any data. Check the ESA ENVISAT page for latest news.

The products presented here are the latest available images of ozone vertical column densities, ozone forecast, ozone loss at 56 hPa and the current antarctic ozone hole size. The data used to produce these information products come from the sensors METOP-A/GOME-2 and ENVISAT/SCIAMACHY and are the result of several algorithms.
