solarConstant top-level constant

EnergyFlux const solarConstant

The mean solar electromagnetic radiation (the solar irradiance) per unit area that would be incident on a plane perpendicular to the rays, at a distance of one astronomical unit (AU) from the Sun.

The solar 'constant' is actually not constant. It has been shown to vary historically in the past 400 years over a range of less than 0.2 percent.

Implementation

const EnergyFlux solarConstant = EnergyFlux.constant(Double.constant(1370));
