Thank you to anyone who can help!

The figure below shows the total daily insolation received at the top of the atmosphere by latitude (y-axis) and month (x-axis). Using the information found in the figure and typical percentages of absorption, scattering, reflection and transmission of incoming shortwave radiation found in the instructional c content for the unit and Figure 2.34 in the textbook, answer the following questions (make sure to include units in your answer). a. How much insolation is received at the top of the atmosphere (in W/m2) for a location at 30°N on August 1st? (1 mark) b. How much of the insolation in a. is reflected by the components in the atmosphere (in W/m2)? (1 mark) c. How much of the insolation in a. is absorbed by the components in the atmosphere (in W/m2)? (1 mark) d. How much of the insolation in a. is transmitted through the atmosphere and received at the surface (in W/m2)? (1 mark) Figure 1.1: Mean daily insolation (W/m2) on a horizontal surface at the top of the atmosphere as a function of the day of the year and the latitude. White areas correspond to the polar night. (Source: http://www.elic.ucl.ac.be/textbook/chapter2_node5_3.xml) 500 450 3ON 350 300 250 30S 150 60S 100 0 Month

Explanation / Answer

a. 450 W/m2

As this falls under the light red category as shown in the figure.

Since typical percentages of reflection, absorption, and transmission in the atmosphere are 26%, 19%, and 55% respectively,

b.  the insolation reflected by the components in the atmosphere is = 450*0.26 = 117 W/m2

c. the insolation absorbed by the components in the atmosphere is = 450*0.19 = 85.5 W/m2

d.  the insolation transmitted by the components in the atmosphere is = 450*0.55 = 247.5 W/m2
