Lecture29 Solar Constant Youtube Atmos 5000 lecture 29: solar constant. The solar constant (gsc) 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. it is measured on a surface perpendicular to the rays, one astronomical unit (au) from the sun.

The solar constant. the average amount of energy that the earth striking the top of the earth's atmosphere from the sun is about 1370 j m 2 s 1 and this quantity is known as the solar constant. the amount that actually reaches the ground can vary enormously and depends on: (a) the angle of the sun's rays (b) the transparency of the atmosphere.
