I found this from Australia which is bothered solely with clouds and refraction. It possibly asks more questions that it answers on here but it also begs the question; Are the right questions being asked?
I think your link is about "atmospheric lensing" of insolation (thus, local) and not the effect of insolation per se. It's 03:30 here and I really need some sleep. Though, I also doubt that the right questions are being asked.
