Hello please answer question 1 to 4. Use the analemma. Kindly be clear on the final answer...you can have it on bold or something

The Analemma

You can calculate the angle of the sun’s rays relative to the Earth’s surface (noon sun angle) by using a graph called an Analemma.  An Analemma shows the latitudinal position of the noon sun relative to the Earth’s surface throughout the year.  The Latitude where the sun is directly over (Vertical) the Earth’s surface on any given day is known as Sub Solar Point  (SSP).

 

The first two pieces of information needed to calculate the ANS is a Latitude and SSP. The distance between Latitude and a SSP is called Zenith Angle (Z).

 

Zenith Angle (Z) is the difference between your latitude and the Sub Solar Point (SSP).

Zenith is an Absolute value and cannot be negative and is measured in degrees!

 

Finding the Zenith Angle:

 

If the Sub Solar Point  (SSP) and your Latitude are in the same hemisphere, you need to take the difference between your latitude and Sub Solar Point  (SSP) (expressed in absolute form).

 

If the Sub Solar Point  (SSP) and your Latitude are in different hemispheres, you need to add your Latitude and the Sub Solar Point  (SSP).

 

Finding the Noon Sun Angle:

 

By knowing Zenith Angle (Z), you can calculate the angle of the noon sun (ANS) for any Latitude on any date using the following formula:

 

Noon Sun Angle (ANS) =90 – Zenith Angle

***Noon Sun Angle is also expressed using the terms ANS or Solar Elevation (SE).  You will see it both ways in this class.

 

Example 1: You want to find the noon sun angle for 100N Latitude on May 21st

 

The Sub Solar Point (SSP) for May 21st is 20oN

 

The equation would be: ANS=90o– (20 – 10) or 80o

 

Example 2. You want to find the noon sun angle for 250S Latitude on May 21st

 

The Sub Solar Point (SSP) for May 21st is 200N

 

The equation would be: ANS = 90o- (25 +20) or 45o

 

ANS is ALWAYS (90- Zenith).

 

A negative answer means the sun never rose above the horizon.

Answer the following questions using the Analemma at to the back of this lab.

 

 

  1. Using the Analemma, determine the Sub Solar Point (SSP) for the following dates. (N or S)
