Solar Radiation: Thee Enginee of Climate

Solar radiation is primary energy source driving Earth 's climate system. The Sun emits electro magnetic radiation across a broad spectrum, including ding visible light, infrared, and ultraviolet flonegths. However, only a fraction of this solar energy reaches Earth' s surface; the rest is absorbed or scattered by atherm throic contribuents such as gases, aerozols, and cloads.

Orbital Variations andSolar Forcing

Albedo: Earth 's Reflectivity andFeedback Loops

Albedo is a measure of how muph incoming solar radiation a surface reflects back into space, expressed as a value between 0 (no reflection) and 1 (total reflection). Earth 's average albedo is approxiately 0.3, meaning about 30% of solar energy is reflectide. However, different surfaces vary widely in their reflectivity:
