Calculate Jordan Retro 10 the zenith angle (Z) using this formula: Z = cos 1 (sinXsinY + cosXcosYcosH). Zenith angle is the angle from the point directly overhead to the point of the sun’s position in the sky. In this equation, X Air Jordan 7s is latitude, Y Air Jordan Spizike is the solar declination angle and H is the hour angle solar declination angle is the angle between a plane perpendicular to incoming solar radiation and the earth’s rotational axis. The solar declination angle varies from +23.5 degrees on summer solstice to 23.5 degrees on winter solstice. The solar declination angle is 0 degrees on the Air Jordan 12s vernal equinox and autumnal equinox.
