2 Changing Aspect Angle Direct Sunlight is more intense and concentrated. Solar Incidence Angle is Latitude and Time/Date Dependent Daily and Seasonal Variation

3 Zenith There is much less atmosphere to travel through directly overhead than on the horizon. The sun is more direct and intense.

4 Daily Solar Intensity By the time the sun gets on the horizon, it is at a grazing angle and heavily scattered, refracted and absorbed.

5 Diurnal Temperature

6 Earth s Tilt (Seasonal) Seasons Reasons Tilt of rotational axis with respect to its orbit around sun Solar Radiation (Earth s daily rotation) More Direct Sun Light Longer Duration of Day Light Hours Orbit Variations (Very Long-Term, Small Effects) tilt eccentricity precession

7 Tilt Earth s rotational axis remains fixed with respect to the stars.

8 Earth s Circle of Illumination 50 % of the earth s surface is illuminated by the sun, every hour of every day.

9 Incident Angle

10 Winter Solstice Sunlight is most direct at the Tropic of Capricorn (23.5 S) on ~ January

19 Solar Altitude Angle Calculation of the Solar Altitude at Local Noon What is your Latitude? What is the Date? For the date and latitude, what is apparent latitude (declination) of the Sun? Calculate the distance in degrees between your latitude and the declination of the sun. 90 degrees minus the latitude declination difference will be the solar altitude at local noon for your location on that date. Solar Altitude = 90 - solar latitude - observer latitude

20 Solar Altitude Angle (Solstice)

22 Solar Altitude Angle Solar Altitude at Local Noon, Russellville, AR What is your Latitude? What is the Date? For the date and location, what is apparent latitude (declination) of the Sun? Calculate the distance in degrees between your latitude and the declination of the sun. 90 degrees minus the latitude declination difference will be the solar altitude at local noon for your location on that date. Solar Altitude at NOON = 90 [Difference in Latitude on Earth between you and direct sun]
