Short summary
Our paper investigates whether it is possible to observe continuous injections of 1 and 2 Tg S y-1 (sulfur per year) into the stratosphere with the currently active satellite occultation instruments. The calculations show that, considering the natural variability and the assumptions made here, the stratospheric aerosols formed from continuous emissions of 1 and 2 Tg S y-1 in the quasi-steady-state phase can be detected, which is not the case in the first month of the 2-year initial phase.
