What is the Solar Hour Angle & How does it work?

The solar hour angle is a measure of the position of the sun in the sky, expressed as an angle from the local meridian. It is used to calculate the amount of solar radiation received at a particular location.

theta = 15^circ times (LST – 12)
theta = solar hour angle in degrees
LST = local solar time in hours

This formula assumes that the sun moves at a constant rate across the sky, which is a reasonable approximation for most purposes.

Frequently Asked Questions
What is the formula for calculating the solar hour angle?
The formula is ΞΈ = 15Β° Γ— (LST – 12), where ΞΈ is the solar hour angle in degrees and LST is the local solar time in hours.
How do I use this calculator to find the solar hour angle?
Input your local solar time into the calculator, and it will compute the solar hour angle for you using the formula ΞΈ = 15Β° Γ— (LST – 12).
Why is the solar hour angle important in meteorology?
The solar hour angle helps determine the amount of solar radiation received at a specific location, which is crucial for understanding climate patterns and energy calculations.
What does LST stand for in the formula?
LST stands for Local Solar Time, which is the time based on the position of the sun relative to a particular location on Earth.
Can this calculator be used for any time of day?
Yes, you can use this calculator at any time of day by inputting the corresponding local solar time to find the solar hour angle.
Is there a specific unit for the solar hour angle?
The solar hour angle is measured in degrees.
How accurate is this approximation of the sun’s movement?
This formula provides a reasonable approximation suitable for most purposes, though it doesn’t account for variations due to Earth’s elliptical orbit or atmospheric refraction.
