Solar Energy And The Atmosphere Pdf

The remainder of the energy passes through the atmosphere with much of it 51 units being absorbed by the earth s surface.

Solar energy and the atmosphere pdf.

The earth atmosphere energy balance is the balance between incoming energy from the sun and outgoing energy from the earth. Energy released from the sun is emitted as shortwave light and ultraviolet energy. Incoming short and intermediate wavelength radiation may be absorbed by gases in the atmosphere reflected back into space from the atmosphere or earth s surface or absorbed by earth s surface. Solar radiation and the atmosphere solar radiation occurs in a range of wavelengths represented by the electromagnetic spectrum.

The solar irradiance is measured in watt per square metre w m 2 in si units solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment. The three types are. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. The second highest energy is also mostly stopped in the atmosphere.

Solar energy is radiant light and heat from the sun that is harnessed using a range of ever evolving technologies such as solar heating photovoltaics solar thermal energy solar architecture molten salt power plants and artificial photosynthesis. When it reaches the earth some is reflected back to space by clouds some is absorbed by the. The highest energy ultraviolet does not reach the planet s surface at all. Of the solar energy that reaches the outer atmosphere uv wavelengths have the greatest energy.

The amount of solar energy received at the top of our atmosphere.
