It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane. [4] [5] At solar noon, the zenith angle is at a minimum and is equal to latitude minus solar declination angle. This is the basis by which ancient mariners navigated the oceans. [6]

The solar azimuth angle is the azimuth (horizontal angle with respect to north) of the Sun's position. [1] [2] [3] This horizontal coordinate defines the Sun's relative direction along the local horizon, whereas the solar zenith angle (or its complementary angle solar elevation) defines the Sun's apparent altitude.
For example, when the Sun is at an elevation of 10°, it appears to be at 10.1°. The Sun's declination can be used, along with its right ascension, to calculate its azimuth and also its true elevation, which can then be corrected for refraction to give its apparent position. [2] [14] [18]
The 50th parallel north is a circle of latitude that is 50 degrees north of the Earth's equatorial plane. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . At this latitude the sun is visible for 16 hours, 22 minutes during the summer solstice and 8 hours, 4 minutes during the winter solstice . [ 1 ]
Mount Whitney (Paiute: Tumanguya; Too-man-i-goo-yah) is the highest mountain in the contiguous United States, with an elevation of 14,505 feet (4,421 m). [1] It is in East–Central California, in the Sierra Nevada, on the boundary between California's Inyo and Tulare counties, and 84.6 miles (136.2 km) [8] west-northwest of North America's lowest topographic point, Badwater Basin in Death ...
Death Valley's Badwater Basin is the point of lowest elevation in North America, at 282 feet (86 m) below sea level. [1] It is 84.6 miles (136.2 km) east-southeast of Mount Whitney – the highest point in the contiguous United States , with an elevation of 14,505 feet (4,421 m). [ 4 ]
The 47th parallel north is a circle of latitude that is 47 degrees north of the Earth's equatorial plane. It crosses Europe , Asia , the Pacific Ocean , North America , and the Atlantic Ocean . At this latitude the sun is visible for 15 hours, 54 minutes during the summer solstice and 8 hours, 31 minutes during the winter solstice . [ 1 ]
