SCIENCE European Space Agency reports positive global recovery of Earth's once depleting ozone layer after 30 years of research

“Climate scientists studying three decades of ozone measurements from seven satellites see a positive trend in global recovery thanks to international efforts to curb ozone-depleting substances.” - ESA

Depletion of the global ozone layer began in the 1970’s - in Earth’s stratosphere - some 11-15km above the Earth’s surface. At one point, scientists monitoring ozone levels recorded a 4-8 percent drop per decade.

“By merging the Climate Change Initiative’s data with NASA’s, we clearly see negative ozone trends in the upper atmosphere before 1997 and positive trends after,”




- Concludes Viktoria Sofieva, Senior Research Scientist at the Finnish Meteorological Institute

In order for this recovery to be noted, scientists used several different satellites over 30 years to record datasets of our planet's atmosphere. These include SAGE II on ERBS, GOMOS, SCIAMACHY and MIPAS on Envisat, OSIRIS on Odin, ACE-FTS on SCISAT, and OMPS on Suomi-NPP.


The results were published in a paper submitted to the Atmospheric Chemistry and Physics journal entitled, ‘Merged SAGE II, Ozone_cci and OMPS ozone profile dataset and evaluation of ozone trends in the stratosphere’.

The merged SAGE–CCI–OMPS dataset consists of recorded anomalies of ozone in 10° latitude bands from 90° S to 90° N and from 10 to 50 km in steps of 1 km covering the period from October 1984 to July 2016.

The paper is a collaborative effort spanning 30 years of research, 10 international scientific institutions including Finnish Meteorological Institute, Helsinki, Finland, Institute for Environmental Physics, University of Bremen, Bremen, Germany and NASA Goddard Space Flight Center as well as over 20 scientists.
