The Contribution of Geomagnetic Activity to Polar Ozone Changes in the Upper Atmosphere

Figure 1

The annual-mean ozone thickness anomalies relative to 40 DU (Dobson Unit) above 10 hPa over latitude range from 60° to 90° from 1979 to 2012. We averaged ozone data in this latitude range with considering the latitude weight. The blue squares and red spots connected with dash lines denote the data points of the NH and the SH, respectively.
