2. Solar constant - Wikipedia

   en.wikipedia.org/wiki/Solar_constant

   The solar constant (G SC) measures the amount of energy received by a given area one astronomical unit away from the Sun. More specifically, it is a flux density measuring mean solar electromagnetic radiation ( total solar irradiance ) per unit area.

3. Solar irradiance - Wikipedia

   en.wikipedia.org/wiki/Solar_irradiance

   Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m 2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation.

4. Solar luminosity - Wikipedia

   en.wikipedia.org/wiki/Solar_luminosity

   Irradiance is defined as power per unit area, so the solar luminosity (total power emitted by the Sun) is the irradiance received at the Earth (solar constant) multiplied by the area of the sphere whose radius is the mean distance between the Earth and the Sun: = where A is the unit distance (the value of the astronomical unit in metres) and k ...

5. Air mass (solar energy) - Wikipedia

   en.wikipedia.org/wiki/Air_mass_(solar_energy)

   The air mass coefficient can be used to help characterize the solar spectrum after solar radiation has traveled through the atmosphere. The air mass coefficient is commonly used to characterize the performance of solar cells under standardized conditions, and is often referred to using the syntax "AM" followed by a number.

6. Radiative forcing - Wikipedia

   en.wikipedia.org/wiki/Radiative_forcing

   The intensity of solar irradiance including all wavelengths is the Total Solar Irradiance (TSI) and on average is the solar constant. It is equal to about 1361 W m −2 at the distance of Earth's annual-mean orbital radius of one astronomical unit and as measured at the top of the atmosphere. [42]

   Bill Clinton is one proud grandpa!. On Monday, Nov. 25, the former President of the United States, 78, appeared on an episode of Live with Kelly and Mark and spoke about how he and the former ...

8. Luminosity - Wikipedia

   en.wikipedia.org/wiki/Luminosity

   In astronomy, this amount is equal to one solar luminosity, represented by the symbol L ⊙. A star with four times the radiative power of the Sun has a luminosity of 4 L ⊙. Luminosity is an absolute measure of radiated electromagnetic energy per unit time, and is synonymous with the radiant power emitted by a light-emitting object.
