Years and years ago I came across a study which discussed the realtime imaging of terrain from above. They talked about how the system worked well near coastal regions due to the amount of salt in the air, but didn't work well inland due to the lack of a conductive medium in the atmosphere ; the waves got scattered.
They figured out that by injecting a conductive artificial aerosol composed of barium salts (IIRC) over inland areas, they could mimic the atmospheric conditions of coastal areas and get the imaging system to perform properly inland.
I have searched for hours and hours for this fucking paper, cannot find it again. The best I could do after a few hours of looking yesterday was this, but it isn't anywhere near as much info as the other paper had.
We have analyzed the effects of Iaser beam propagation on imaging in the cases of linear and nonlinear radiative transfer...
Performance of tracking systems has explicitly been associated with the properties of target signatures, and implicitly with the properties of the intervening medium, For HEL beams, the scattering and absorption cross sections of the medium vary with the value of the radiation flux; the beam propagation becomes nonlinear.
...by the very nature of nonlinear propagation the widest MTF corresponds to the largest propagation distance, if the high energy beam is used for imaging. The low-energy probe beam, on the other hand, would propagate through a teneous aerosol cloud, thus experiencing enhanced broadening as the path length increases.

I live in a town with 5 military bases and the skies are virtually saturated with artificial aerosol trails every day. IMO they're doing it to enhance a monitoring system which can track targets on the ground in real-time. Will keep looking for the other paper, as I consider it to be the one thing that can explain all of this.
I've lived in this city for all of my life and this shit in the sky was non-existent before 1997.
