Overview

This investigation demonstrates the impact of stratospheric aerosol injections on aerosol profile retrievals in various latitudes, indicating wavelength considerations for accurate measurements.

Key Points

The central aim is to explore the zero transmission problem and its implications on retrieving stratospheric aerosol extinction profiles from satellite measurements.
Analyzed continuous injections of 30 Tg S yr−1 using MAECHAM5-HAM and SCIATRAN.
Examined suitable wavelengths for aerosol profile retrievals based on latitude.
Conducted simulations for lower emission rates and their effects on transmission.
Different latitudes require varying minimum wavelengths for effective aerosol profile retrievals.
520 nm is insufficient for aerosol retrievals at 5° N but necessary wavelengths increase for higher latitudes.
Longer wavelengths are necessary closer to the area of injection due to the zero transmission problem at shorter wavelengths.
