An update on ozone profile trends for the period 2000 to 2016

Atmospheric Chemistry and Physics (2017)

Ozone profile trends from 2000 to 2016 from several merged satellite ozone data sets and from ground-based data measured by four techniques at stations of the Network for the Detection of Atmospheric Composition Change indicate significant ozone increases in the upper stratosphere, between 5 and 1 hPa. Near 2 hPa, ozone has been increasing by about 1.5 % per decade in the tropics (20◦ S to 20◦ N), and by 2 to 2.5 % per decade in the 35 to 60◦ latitude bands of both hemispheres. These new observations confirm positive trends of upper stratospheric ozone already reported.
