Editing Diffuse sky radiation (section)

==Under an overcast sky==
There is essentially no direct sunlight under an [[overcast]] sky, so all light is then diffuse sky radiation. The flux of light is not very wavelength-dependent because the cloud droplets are larger than the light's wavelength and [[Mie scattering|scatter all colors]] approximately equally. The light passes through the [[transparency and translucency|translucent]] clouds in a manner similar to [[frosted glass]]. The intensity ranges (roughly) from {{frac|1|6}} of direct sunlight for relatively thin clouds down to {{frac|1|1000}} of direct sunlight under the extreme of thickest storm clouds.{{Citation needed|date=February 2009}}
