Description Calculates azimuth in degrees clockwise from north from a target lat/lon to a viewing lat/lon (e.g. direction to the sun from a target surface). This is an approximation assuming a spherical planet, which is more than sufficient for most applications.
Arguments and Return Values Inputs are target lon, target lat, viewing/source lon, viewing/source lat.
Usage Syntax: azimuth(target_lon, target_lat, source_lon, source_lat) All inputs and output are in degrees and longitude is east. Inputs can be arrays.
