What is the altitude of the sun?
The altitude of the sun is the angle between the sun and the observer's horizontal plane. It changes throughout the day as the sun rises and sets. At solar noon, when the sun is at its highest point in the sky, the altitude is its maximum.
What instrument measures the altitude of the sun?
An instrument that measures the altitude of the sun is called a sun altitude indicator or a sun sensor. These instruments typically use a combination of sensors, such as inclinometers and light sensors, to determine the angle of the sun relative to the horizon. This information is crucial for various applications, including navigation, astronomy, and solar energy systems.
What is solar altitude?
How high the sun is in the sky. The angle between the horizon and the sun. When the sun is directly overhead (eg, at the equator) the solar altitude is 90°. In Canberra in winter, the solar altitude is 30°.
What happens as the altitude of the sun increases?
As the altitude of the sun increases, the intensity of sunlight reaching the Earth's surface increases, leading to higher temperatures. This can result in warmer weather and more direct sunlight which is why midday tends to be the warmest part of the day.
Can bats go near the sun?
Bats wouldn't be able to reach the altitude (height) on getting to the sun.

How much higher is the sun at noon compared to midnight at latitude 80 degrees north - on days where the sun never sets?
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
What is the relationship between the altitude of the Sun and the intensity of insolation at a particular area?
As the altitude of the sun increases, the intensity of insolation for that area will increase as well.

Why does the sun's altitude in the sky change through the year?
The earth revolves around the sun.
Why does the sun's altitude in the sky change through out the year?
The earth revolves around the sun.

As the altitude of the sun increases, the intensity of sunlight reaching the Earth's surface increases, leading to higher temperatures. This can result in warmer weather and more direct sunlight which is why midday tends to be the warmest part of the day.
What will be the altitude of the sun on 21st June at the equator?
On the 21st of June at the equator, the sun's altitude will be at its highest point, which is 90 degrees. This is known as the summer solstice, where the sun reaches its highest point in the sky.
What is the suns altitude?
The sun's altitude refers to its angle above the horizon, measured in degrees. This angle varies throughout the day and changes with the seasons due to the tilt of the Earth's axis and its orbit around the sun. At solar noon, the sun reaches its highest point in the sky for that day, which is when its altitude is at its maximum. The altitude can be calculated using the observer's latitude, the date, and the time of day.
How is intensity of insolation affected by the altitude of the sun?
The intensity of insolation is affected by the altitude of the sun; the higher the sun is in the sky (higher altitude), the more direct the solar radiation is, resulting in higher intensity. When the sun is lower in the sky, the sunlight has to pass through a greater thickness of the Earth's atmosphere, which can scatter and absorb some of the radiation, reducing its intensity.
Why do shadows lengths change throughout the year?
Shadows change length throughout the year because the altitude of the Sun above the horizon changes. The altitude (height above the horizon) of the Sun changes as the Earth revolves around the Sun each year. This is due to Earth's axis being at an angle. In the Northern Hemisphere, the North Pole is pointing away from the Sun on the winter solstice (around Dec. 21) and for the Northern Hemisphere the Sun is at its lowest altitude and shadows will be the longest of the year. On summer solstice (June 21), the Sun is at its highest altitude and shadows are the shortest of the year. Janice VanCleave
