Part III: Earth Sun Geometry Calculating solar elevations above the horizon facing the Equator (0°) (90-latitude) + solar declination Solar declination is positive when the sun is overhead in the same hemisphere as the target location & is negative when the sun is overhead in the hemisphere opposite the target location For example, Los Angeles is located 34°N. Thus, from 3/21 thru 9/22 solar declination is positive because the sun is overhead in the northern hemisphere. Solar declination is negative 9/23 thru 3/20 because the sun is overhead in the southern hemisphere Declination changes rapidly within 5 weeks of an equinox (3/20 & 9/22) and very slowly within 5 weeks of a solstice (12/21 and 6/21). Declination is 0 on 9/22 and 3/20. It is 23.5 on 6/21 and 12/21. On 5/20 and 7/20 it is 20°N. On 4/20 and 8/20 it is 12°N On 11/20 and 1/20 it is 20°S On 10/20 and 2/20 it is 12°S 1. Calculate the solar elevations at the following places June 21 Dec 21 Mar 20/Sept 22 Anchorage AK 61°N St Paul, MN 45°N Atlanta, GA 34°N Honolulu, HI. 21°N *Quito, Ecuador 0° 66.5° 66.50 90° Valparaiso, Chile 32°S 2. Which two cities will have fairly consistent daylengths? Which will have the longest daylength yet the lowest solar elevation? *Facing north in June and south in Dec
