Solar azimuth angle: The solar azimuth angle is the azimuth angle of the sun.  It defines in which "direction" the sun is, whereas the solar zenith angle or its complementary angle solar elevation defines how high the sun is.  There are several conventions for the solar azimuth, however it is traditionally defined as the angle between a line due south and the shadow cast by a vertical rod on Earth.  This convention states the angle is positive if the line is east of south and negative if it is west of south.  For example, due east would be 90° and due west would be -90°.  Another convention is the reverse; it also has the origin at due south, but measures angles clockwise, so that due east is now negative and west now positive.
