In SamsaRaLight: Simulate Tree Light Transmission Using Ray-Tracing

Compute sun azimut

Description

Computaion of sun azimut for a given height angle reference system with angle origin on X > 0 axis and trigonometric rotation

Usage

sl_compute_sunazimut(
  latitude_rad,
  declination_rad,
  hour_angle_rad,
  height_angle_rad,
  southazimut_ccw_rad
)

Arguments

latitude_rad	double - Latitude of the plot (in radians)
declination_rad	double - Declination angle in radians: angle between the equator and a line drawn from the centre of the Earth to the centre of the sun
hour_angle_rad	double - Angle which the sun moves across the sky (in radians)
height_angle_rad	double - Angle between beam and soil (in radians)
southazimut_ccw_rad	double - Azimuth of south counterclockwise from x axis in the (x,y) system (in radians)

Value

a sun azimuth value
