Which airborne sugars are we talking about here - candy floss clouds, sucrose snow, glucose graupel, fructose fog, lactose lockets or what?

Carbon dioxide, actually. Sugars are carbohydrates.

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose.
