天顶角、太阳方位角和太阳高度角辨析 - CSDN博客
2020年7月24日 · 太阳天顶角（Solar Zenith Angle）是指太阳光线入射方向和天顶方向的夹角，是高度角的余角（天顶角=90°- 高度角）。 当 太阳 的 高度 角 为90°时， 太阳 位于 天 顶，此时 太阳 的 天 顶角 为0° ...
Solar zenith angle - Wikipedia
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.
Zenith - Wikipedia
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).
太阳高度角 - 维基百科，自由的百科全书
太陽高度角（英語： solar elevation angle ），也称太阳高度，是指某地的太阳光线与当地地平面的所交的最小线面角，這是以太陽視盤面的幾何中心和理想地平線所夾的角度。
Elevation Angle - PVEducation
The elevation angle (used interchangeably with altitude angle) is the angular height of the sun in the sky measured from the horizontal. Confusingly, both altitude and elevation are also used to describe the height in meters above sea level.
NOAA Solar Position Calculator - National Oceanic and …
Results are given in the following units: Equation of Time in minutes of time; Solar Declination in degrees, with positive to the north; Azimuth in degrees clockwise from north; Elevation in degrees up from the horizon; Cosine of Solar Zenith Angle is unitless.
Solar Elevation Angle – Calculating Altitude of Sun - SolarSena
2022年6月26日 · What would be the zenith angle if the solar elevation angle is 38.5°? The addition of both angles equals 90°, so the zenith angle = 90°−38.5° = 51.5°. How solar panels and the elevation angle of the sun are related?
The Science Behind the Solar Zenith Angle Explained - SunValue
2024年8月20日 · Solar Zenith Angle: The angle between the sun’s rays and a vertical line directly above a location on Earth. It impacts solar panel efficiency by determining how directly sunlight hits the surface. Calculation Factors: Includes solar declination, latitude, and hour angle. The formula to calculate it is:
Zenith Angle - an overview | ScienceDirect Topics
The zenith angle is defined by (8-61)cosZ=cosϕ cosδsuncoshr+sin δsunsinϕ,where ϕ is latitude, δsun is the declination of the sun (which ranges between +23.5° on 21 June to –23.5° on 22 December),20 and hr is the hour angle (0° ≡ noon).

Spherical coordinate system - Wikipedia
The elevation is the signed angle from the x-y reference plane to the radial line segment OP, where positive angles are designated as upward, towards the zenith reference. Elevation is 90 degrees (= π / 2 radians) minus inclination .
