Latitudes & Sun Angles
April 3rd, 2002
| Sun angle data is now available from the sites located above. Compare the sun angle measurement with each site's latitude (degrees north or south of the equator) in the chart below. Could you predict what the sun angle would be at other sites if you know its latitude? Why is that so? In other words, what does the sun angle have to do with a location's latitude at local noon at the spring equinox? |  |
