ESA's Envisat satellite has measured record low levels of ozone over the Euro-Atlantic sector of the northern hemisphere during March...
The ozone layer has been routinely monitored from space over the last three decades, witnessing a record loss over the South Pole in 2006. In 2009, ERS-2, Envisat and MetOp contributed to satellite data showing there is a slow trend towards recovery in total ozone.
