If you’re sighted and have experienced a heavy nighttime snowstorm in an illuminated urban area, you know what I’m talking about: the sandwich of light between the snowy white ground and snowy white sky, infusing the landscape with the soft white light of a frosted light bulb--sometimes enough to read by, certainly enough to see by.

Maybe it’s a form of skyglow? https://en.wikipedia.org/wiki/Skyglow “Skyglow is significantly amplified by the presence of snow, and within and near urban areas when clouds are present.”

I know it’s nearly a year after the fact, but I neglected to thank you for your help-and for a beautiful new meteorological term I’d not known.
