Solar azimuth angle information


The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position.[1][2][3] This horizontal coordinate defines the Sun's relative direction along the local horizon, whereas the solar zenith angle (or its complementary angle solar elevation) defines the Sun's apparent altitude.
