Document Summary
Energy essentials, energy balance at the troposphere, energy balance at the earth"s surface. Allows visible light to reach earth"s surface. Short wave energy from the sun (gamma rays, x-rays, uv) Long wave energy from earth (infrared, microwave, radio waves) Transmission: passage of energy through the atmosphere or water. Insolation input: all radiation received at earth"s surface direct and indirect. Insolation in the atmosphere encounters gases, dust, clouds, and smoke. ~50% of insolation makes it to the earth"s surface. Changing direction of light"s movement, without altering its wavelength. The assimilation of radiation by molecule of matter. Insolation (light) is bounced off a surface without being absorbed or scattered. The conversion of energy from one from to another. *heats the earth"s atmosphere (as absorption occurs, increase in temperature) *occurs when insolation is not absorbed, but is bounced in all directions. *scatter agents: dust, pollutants, ice, cloud droplets, water vapor. *diffuse radiation: the downward component of scattered light.
