# EARTH SCIENCE LAB Insolation

Directions for entering values (unless otherwise directed):
1. Enter all values without commas - example 5,678 would be entered as 5678.
2. Enter all decimal values less than one with a zero before the decimal - example 0.53, 0.32.

### Insolation and Latitude - Part I

Theta - Round all decimals to 1 decimal place.
Ground Area - Round all decimals to 2 decimal places.
Energy Intensity - Round all decimals to the nearest whole number.

Given the Latitude, determine Theta, Ground Area and Energy Intensity at the surface during an Equinox.

 Latitude Theta, ° a Ground Area, m2 Energy Intensity, W/m2 1. 23.5°N ° 1 m2 m2 W/m2 2. 9°S ° 1 m2 m2 W/m2 3. 41°N ° 1 m2 m2 W/m2 4. 89°S ° 1 m2 m2 W/m2 5. 23.5°S ° 1 m2 m2 W/m2 6. 66.5°S ° 1 m2 m2 W/m2 7. 78°S ° 1 m2 m2 W/m2 8. 12°N ° 1 m2 m2 W/m2 9. 52°N ° 1 m2 m2 W/m2 10. 32°N ° 1 m2 m2 W/m2

### Insolation and Latitude - Part II

Given the Latitude, determine the percent of insolation recieved at the surface during the Summer (SS) or Winter (WS) Solstice.

Theta - Round all decimals to 1 decimal place.
Ground Area - Round all decimals to 2 decimal places.
Energy Intensity - Round all decimals to the nearest whole number.

Given the Latitude, determine Theta, Ground Area and Energy Intensity at the surface during an Equinox.

 Latitude Theta, ° a Ground Area, m2 Energy Intensity, W/m2 11. (SS) 10°N ° 1 m2 m2 W/m2 12. (SS) 9°S ° 1 m2 m2 W/m2 13. (SS) 41°N ° 1 m2 m2 W/m2 14. (SS) 85°N ° 1 m2 m2 W/m2 15. (SS) 23.5°S ° 1 m2 m2 W/m2 16. (WS) 66°S ° 1 m2 m2 W/m2 17. (WS) 78°S ° 1 m2 m2 W/m2 18. (WS) 12°N ° 1 m2 m2 W/m2 19. (WS) 52°N ° 1 m2 m2 W/m2 20. (WS) 32°N ° 1 m2 m2 W/m2

### Insolation in the Quad Cities

A vertical pole, 1000 mm in length, is placed in the ground on the campus of Black Hawk College. At various times throughout the day, Vernal Equinox (VE), the length of the shadow cast by the sun is measured. Using this information determine the amount of insolation recieved at the surface.
Energy Intensity - Round all decimals to the nearest whole number.

 ShadowLength Energy Intensity, W/m2 21. (VE) 900 mm W/m2 22. (VE) 1000 mm W/m2 23. (VE) 1111 mm W/m2 24. (VE) 1250 mm W/m2 25. (VE) 1505 mm W/m2 26. (SS) 2200 mm W/m2 27. (SS) 3045 mm W/m2 28. (WS) 4356 mm W/m2 29. (WS) 5721 mm W/m2 30. (WS) 10765 mm W/m2

A vertical pole, 1000 mm in length, is placed in the ground on the campus of Black Hawk College on the Vernal Equinox (VE). With the sun at its highest point in the sky (high noon), what is the minimum length of the shadow cast by the sun? Round your answer to the nearest millimeter.
Minimum Possible Shadow Length during the Vernal Equinox = mm

### Annual Insolation

Using the Daily Average Insolation per Month table in your lab manual, calculate the total annual insolation for 60°S Latitude.
Round all decimals to 2 decimal places.

Total = W/m2

Using the Daily Average Insolation per Month table in your lab manual, calculate the total annual insolation for 10°S Latitude.
Round all decimals to 2 decimal places.

Total = W/m2
