  • Irradiance of sunlight; power per unit area on the Earth's surface
  • Insolation, solar radiation energy per unit area during a given time
    • Direct insolation, insolation which reaches a location on Earth after absorption and scattering in the atmosphere
  • Total solar irradiance (TSI), the amount of solar radiative energy incident on the Earth's upper atmosphere
