It’s a great read , a quick understandable resource . My son did a report on this along with different species a few years back .I think that is where we see separation between the fog I get, in my area. Where you can see through it, about 40-50 ft but not further, and the fog the foggers put out that you cant see an inch passed, I think the later the "wetting fog" is 100% RH.
Could be completely off base though.
I had read about this long ago, and read that link, and I think that is basic of what I remeber, but I would have to look more in depth, they kind of touch on that with what you posted too though.
