Fig. 3: The zonal mean column sAOD (stratospheric aerosol optical depth, background aerosol + volcanic aerosol).

The top panel shows the OMPS LP (the Ozone Mapping and Profiling Suite Limb Profiler) at 997 nm. The middle and bottom panels show the simulated near-infrared sAOD (stratospheric aerosol optical depth) for cases without (the SO2only case) and with the water injection (the SO2_H2O case).
