combined quantity of diffuse sky and (ground-)reflected solar radiation received on a plane surface [W/m2], diffuse Strahlung
solar radiation which can not be focused easily because it passes through cloudy skies.
Solar radiation which arrives at the point of observation after scattering due to clouds, fog, haze, dust or other particles in the atmosphere.
Indirect sunlight that is scattered from air molecules, dust and water vapor.
Scattered radiation from the sun that comes from all portions of the sky.
The sunlight received indirectly, as a result of scattering due to clouds, fog, dust, moisture vapor or other substances in the atmosphere. See also: Direct radiation, Global radiation
Solar radiation, scattered by water vapor, dust and other particles as it passes through the atmosphere, so that it appears to come from the entire sky. Diffuse radiation is higher on hazy or overcast days than on clear days.
Radiation received from the sun after reflection and scattering by the atmosphere and ground.
Radiation from the sun that reaches the earth after it is reflected from other substances, such as moisture or other particles in space.
