The zenith angle at your site is called Z. TAN(Z) = L/H. L is the true length of the shadow and H is the height of the pole. Your calculator should give you the inverse tangent function, often designated as TAN-1 or ATAN on the calculator keys. Use the degree mode of the calculator rather than the radian mode for angles.

Calculate the area of the field of view of the tube by squaring the result in part 4 and multiplying by pi (3.1415926). Notice that pi is stored for you in the calculator (lower center). Area = _____. The result is in a solid angle measure called steradians. The area of the entire sky in steradians is 4 or about 12.566.

Here is a diagram the shows the details of the computations. Here theta is the difference in the elevation or altitude of the sun, and D is the distance between the two observing locations. Note that this equation correctly describes the situation even if one of the observing locations does not happen to have the sun at the zenith.

The length of the shadow and the height of the gnomon form two sides of a right triangle. The angle at the top, ψ (psi), between the hypotenuse and the gnomon, is the one of interest (Figure 2). Fig. 2. The tangent of angle ψ is, by definition, the (opposite side)/(adjacent side) = (shadow’s length)/(gnomon’s height): tan ψ = s/h.
