On the recovery of stratospheric ozone

Since then, the abundance of ozone-depleting substances (ODS) regulated by the Montreal Protocol have peaked by the mid or end of the nineties depending on...

International audience The ozone layer has been under surveillance since the discovery of the ozone hole over Antarctica in the early eighties.
