Lecture 7: Chapter 4 The passage of shortwave and longwave energy through the atmosphere or water is called: ______________ measures the amount of electromagnetic energy striking a surface perpendicular to the sun’s rays at the top of the thermosphere _______________ the amount of energy received at the top of the Earth's atmosphere (top of the thermosphere) on a surface that is _______________ to the Sun’s rays (at the average distance of the Earth from the Sun). The generally accepted solar constant is 1368 W/m 2, which is a satellite measured _______________. Insolation may be transmitted several ways: 1. 2. 3. 4. Scattering is: Small gas molecules in the air scatter _______ wavelengths of light. The _______ the wavelength, the greater the scattering; the _________the wavelength, the less the scattering. The sky is blue because: During the day, the rays are also more ______, and experience less scattering than low-angle rays, which have to travel farther. Sunsets are red and orange because in the evening, when the sun’s angle is greater, the rays are traveling farther through the atmosphere, and the ____________ get scattered out (redirected) sooner, before reaching our eyes, leaving ___________________ to be reflected. Smog appears white because the ______ particles associated with air pollution scatter all wavelengths of visible light. Some insolation is diffused by clouds and atmosphere and transmits to earth as diffuse radiation which is: Refraction is a:

As insolation enters the atmosphere, it passes from one medium to another, from virtually empty space into atmospheric gases, or from air into water. This subjects the insolation to a ____________, which also shifts its direction. Refraction of sunset :
