Fig. 4: Observed 2D-filtered changes in stratospheric ozone mixing ratios and the associated simulated instantaneous radiative forcing during 2022 and 2023 following the Hunga eruption.
From: The January 2022 Hunga eruption cooled the southern hemisphere in 2022 and 2023
a, b show the zonal- and annual-mean latitude–altitude variation of the changes in stratospheric ozone mixing ratios for 2022 and 2023, respectively. c, d present the latitude–altitude distribution of the differences in net (longwave + shortwave) radiative heating rates (ΔNRHR) for stratospheric ozone for 2022 and 2023, respectively.
