Hi

I'm trying to look at the potential effects of solar radiation management geoengineering on low Earth orbit. It's been suggested to me that volcanoes may have a comparable effect, as they are typically used as an analogue. Does anyone have experience of either observing or modelling the impact of of volcanoes on low Earth orbit? I'm specifically interested in issues of orbital Decay

The troposphere cools, the stratosphere warms. It's unclear what the net effect is

I have no experience.  Some thoughts-- Earth atmosphere mass:  5.15*10^18 kg.   Mass of gas emitted by Mt. Pinatubo in 1991:  2.5*10^11 kg.  On the other hand, the earth atmosphere is expected to contract by about 1% due to cooling.  Satellite decay would be less.
