WebJun 26, 2024 · The zenith is the point in the sky directly above the observer, and the solar zenith angle is the angle between the sun and zenith with the observer. The zenith angle is maximum when the elevation angle is minimum. As a result, in the morning and evening, the zenith angle is highest, while at solar noon, it is minimum. WebLast updated: 23 Feb 2024 The zenith is the point in the sky vertically straight above the observer. It is the point where the observer's sight-line is perpendicular to the Earth's atmosphere, and hence where the smallest amount of … WebFigure 2 shows the local coordinate system in which the view angles are defined, with θ representing zenith angles and ϕ representing azimuth angles.
