Reflectivity of planets

WebAlbedo is the integrated product of incident solar radiation spectral composition and the spectral reflectivity of the object. Outside the atmosphere, solar radiation spectral composition is relatively constant, peaking at about 0.5 μm, decreasing rapidly at shorter wavelengths to small amounts at 0.2 μm, and decreasing less rapidly at longer wave … WebIn addition to scattering or absorbing radiation, aerosols can alter the reflectivity, or albedo, of the planet. Bright surfaces reflect radiation and cool the climate, whereas darker surfaces absorb radiation and produce a …
