How can reduced atmospheric transparency affect radiative balance?
Answer and explanation
Correct answer: Absorption and scattering of solar radiation may increase, altering radiation reaching the surface
Atmospheric transparency describes how freely radiation passes through the atmosphere. Dust, smoke, aerosols and absorbing gases can reduce transparency by scattering or absorbing incoming solar radiation. This changes the amount and distribution of energy reaching the surface and may also alter outgoing radiation, thereby affecting radiative balance. Reduced transparency does not mean that all radiation is blocked or unchanged.
