Do "aerosol shields" protect big emitters from the impact of their own GHGs?
Your general line of thinking is correct. However, here are a few things that make the whole concept somewhat more complicated:
It is widely accepted that the general tendency of "global dimming&...

How to estimate the settling time of atmospheric particulates as a function of aerodynamic size?
I took a class once, and we had an approximate equation for an particle (equation sheet is still up):
$$\frac{d\vec{v}}{dt}=\frac{\rho_{particle}-\rho_{air}}{\rho_{particle}}\vec{g}-\frac{3\rho_{air}...

How far downwind of a covid-19 emitter has a 1000-fold reduction in PPM?
As I said in my comment, viruses aren't my area (concerning units). But the answer is actually unitless. The exact answer you seek is dependent on a couple of different variables:

Aerosol injections to manage European heatwaves?
My question was naïve to the weather dynamics —so the answer is technical: the heat is on the ground, not in the stratosphere.
So there are two things, infrared deflection into space and radiative ...
