The same a what the sun already has to deal with, really. If your reflection and focus were somehow 100% perfect (impossible, but maybe you could get close) then attenuation from the atmosphere would be the same as what happens to ordinary sunlight over the same surface area, since that also has to pass through the same amount of atmosphere.

Right, but in the daytime, the portion of sunlight that is scattered on the way through the atmosphere to a given spot is partially made up for by sunlight that was scattered to that spot away from other areas, which wouldn’t happen under this scheme.
I’m curious how much scattering occurs - I have no idea how to find or model that.

Oh, yeah. If you’re very close to the horizon and reflecting light that’s already plowed through most of the atmosphere at a very shallow angle. Tons, I’m sure.
