I was thinking instead perhaps more
easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater
shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in precipitation that can be caused by SW - radiation - based «GE» (although aerosols that actually absorb some SW in the troposphere while shielding the surface would have the worst
effect in that way, I'd think)... strategic distribution of solar shading has been suggested with precipitation
effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).
Preset filters let you
easily apply quick
effects, but Polarr also offers more robust editing tools for tweaking exposure, contrast, highlights,
shadows and color temperature, as well as the ability to tweak the entire photo or through more limited radial, gradient and brush - based edits.
