Solar radiation scattered by particles in the atmosphere.

Secondary radiation belonging to the same radiation type as the original radiation, produced in the interaction of the original radiation with a material medium. The interaction can be characterized by a reduction in radiation energy and/or by a change in the direction of the radiation.

Radiation that has been reflected from particles, disrupting the original direction of the beam. Click Shining On (Figure 3) to see solar components

Radiation that, during passage through matter, has been deviated in direction and may have had its energy diminished.

Particulate or EM radiation that has undergone a change in direction with or without a change in energy, during its passage through intervening matter.

Radiation that, during passage through matter, is changed in direction (the change is usually accompanied by a decrease in energy).

Radiation that has undergone one or more scattering processes. See also diffuse radiation, single-scattering, multiple-scattering.
