Not exact matches
The width
of the angular distribution
of scattered light increased suddenly at the phase transition.
Aerosols that are close in size or larger than the wavelengths
of visible
light tend to
scatter all colors indiscriminately,
increasing the overall brightness
of the sky but dampening color contrast.
And, since blue
light is most easily
scattered by our planet's atmosphere, many fear that an
increase in the use
of LEDs may substantially
increase light pollution even if the total amount
of emitted
light holds steady.
Atmospheric haze and certain pollutants that
scatter visible
light are nearly transparent to parts
of the infrared spectrum because the
scattering efficiency
increases with the fourth power
of the frequency.
The fraction
of the
light that
scatters back out to space is responsible for the
increased albedo and the cooling effect from sulfate aerosols.
Scattering efficiency
increases as cloud drops approach the wavelength
of the
light, which for our purposes means smaller cloud drops.
