Solar observation for azimuth
The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position. 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. See more 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 … See more A 2024 publication presents a method that uses a solar azimuth formula based on the subsolar point and the atan2 function, as defined in Fortran 90, that gives an unambiguous … See more • Solar Position Calculators by National Renewable Energy Laboratory (NREL) • Solar Position Algorithm for Solar Radiation Applications (NREL) See more The following formulas assume the north-clockwise convention.
