On the chart, use the data to plot the average daily insolation at the top of the atmosphere (in W>m2) for the 22nd day of each month at the equator, 45° N, and 90° N. Connect the values for each latitude with a labeled line (you may also use a red line for the equator, a green line for 45° N, and a blue line for 90° N).
Answer the following questions.
