O3 variability in the troposphere as observed by IASI over 2008-2016 - Contribution of atmospheric chemistry and dynamics

Editors’ Highlight—Thanks to many years of satellite measurements, there are now datasets with sufficient length of record and density of coverage to allow spatial analysis of interannual variability of tropospheric ozone. This study analyzes eight years of ozone data to identify the main geophysical drivers of its regional and temporal variability. Tropospheric ozone is important for human and ecosystem health, for photochemistry, and for its climate/radiative forcing impacts so understanding long-term variations and trends is of value to the international community.
