Best Answer: Good question. On average clouds reflect 60% of incoming solar radiation which includes short wave UV. The thicker the cloud the greater the reflection, from 60 - 90%. For thin clouds the albedo, or relection is 30 - 50%, which explains why we can still receive UV on cloudy days.

Sunlight shining through clouds, giving rise to crepuscular rays. Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light.On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat.n Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.
