The solar zenith angle is the zenith angle of the sun, i.e., the angle between the sun’s rays and the vertical direction. It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane.
The Zenith Angle is a science fiction novel by American writer Bruce Sterling, first published in 2004, about a pioneering expert in computer and network security with a traditional hacker personality named Derek Vandeveer.
In a scientific context, the zenith is the direction of reference for measuring the zenith angle (or zenith angular distance), the angle between a direction of interest (e.g. a star) and the local zenith - that is, the complement of the altitude angle (or elevation angle).
21 mag 2024 · The zenith angle is the angle between a point of interest and the zenith — the point directly overhead. In a three-dimensional coordinate system, the zenith is the axis perpendicular to the horizontal plane. Zenith angle is measured from a local zenith, meaning that it changes based on the location of the person or device making ...
The zenith angle is the angle between the sun and the vertical. The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation.
30 mag 2024 · The zenith angle is an angle measured from the z-axis in spherical coordinates, denoted phi in this work. It is also known as the polar angle and colatitude.
When observing a given point on the Earth's surface from a satellite-based instrument, the Solar Zenith Angle (SZA) is the angle between the local zenith (i.e. directly above the point on the ground) and the line of sight from that point to the sun.
