Solar Incidence; Seasonal Variation; Incident Energy; Time of Equivalent Direct Exposure

The Sun is the driver of all energy on the surface of the Earth. Besides all forms of life, ocean currents, winds and weather systems derive their energy from the Sun. At a distance of about 149.6 million km from the Sun, the Earth receives solar radiative energy of nearly 1,361 W/m2 which remains fairly constant at the location of one astronomical unit away. However, the energy received at the surface of the Earth varies with the angle of incidence on the surface, which in turn depends on the latitude, time of day and also, the position of the earth in its orbit. It is the difference in incident energy that results in thermal and pressure gradients driving the vast magnitude of wind and ocean currents. The incident radiative power per unit area (I) is related to the Solar Constant (Io) and angle of incidence (i) as I = Io cos (i). To understand the variation of incident solar energy on the Earth, it is imperative to understand the variation of this angle (i) with time, as the Earth performs its celestial dance around the Sun. This paper is an attempt to completely describe and determine the angular position of the Sun with reference to any particular location on the Earth at any particular time. Consequently, it is possible to chart out the incident solar energy across the span of a year at various latitudes on the Earth. Using this relation, it is also possible to determine the length of a day at various times of the year at various locations on the Earth and also how the peak angle of the Sun at its Zenith with respect to any location on the Earth varies with the time of the year.
