• Geog 30 1 • Page 1 of 5 KEY Part 1: Insolation 1) Refer to the data in Figure 16 -2 above. Use the chart below to plot the altitude of the Sun at noon on the 22 nd of each month for the equator . If there are negative angels, record them as 0°. After you have charted each value, connect them with a line and label it “Equator.” Repeat this for 45°N and 90°N, charting the solar altitude for each month, and then co nnecting the values with a line. Be sure to label the lines 45°N and 90°N. Insolation • Geog 30 1 • Page 2 of 5 Using your completed chart from Question 1 on the previous page, answer the following: 2) Does the equator or 45°N have a higher noon solar altitude on June 22? 3) Note the noon solar altitude of 45°N on January 22. Will the noon solar altitude at the North Pole ever get this high? 4) We’ve learned this week that angle of incidence, day length and atmospheric obstruction all influence insolation patterns. Let’s imagi ne for a moment ONLY angle of incidence influences insolation patterns. a. Which latitude would get the most insolation on December 22? b. Which latitude would get the least insolation on December 22? c. Which latitude would get the most insolation on June 22? d. Which latitude would get the least insolation on June 22? • Geog 30 1 • Page 3 of 5 5) Refer to the data in Figure 16 -4 above which lists the average daily insolation at the top of the atmosphere on the 22 nd of each month . Use the chart below to plo t this information for the equator, 45°N and 90°N . After you have charted each value, draw a connecting line for each latitude and label the lines. • Geog 30 1 • Page 4 of 5 Remember, you just charted the value for incoming insolation at the top of the atmosphere, before moving through the atmosphere and encountering any atmospheric obstruction. Refer to this chart and answer questions 6-11 : 6) Which latitude has the least variation of insolation at the top of the atmosphere through out the year ? Explain why. (You wi ll not receive credit if you don’t explain why) 7) Which latitude has the greatest variation at the top of the atmosphere throughout the year? Explain why . 8) When does 45°N get the most insolation at the outer atmosphere? 9) Compare this value to th e equator of the same month. Which latitude receives more insolation at the outer atmosphere? Explain this variation . 10) When does the equator have the greatest insolation at the outer atmosphere? 11) When does the equator have the least insolation at the outer atmosphere? Explain this variation . • Geog 30 1 • Page 5 of 5 12) Use the data table and chart below to plot the relationship between angle of incidence and the percentage of radiation reaching the Earth’s surface through the atmosphere. Connect your plotted values with a line. 13) Use your completed chart above and Figure 16 -2 on Page 1 to estimate the percentage of radiation passing through the atmosphere to the surface at noon on June 22 at the equator, 45°N and 90°N. 14) If the effects of the atmosphere are taken into account, which latitude would have the greatest decrease in average daily insolation in June compared to the value shown in problem 4? Explain why.
