Solar flux on earth.

Free home 5 739 views. Solar radiation is the earth primary natural source of energy and by a long way. From the earth system 2 ess200a prof. Each measurement of the 10 7cm solar flux is expressed in three values.

The observed adjusted and ursi series d values. The solar constant is denoted s 0 the solar flux density insolation onto a plane tangent to the sphere of the earth but above the bulk of the atmosphere elevation 100 km or greater is. The solar constant includes all types of solar radiation other than neutrinos not just the visible light. The observed value is the number measured by the solar radio telescope.

The solar constant g sc is a flux density measuring mean solar electromagnetic radiation solar irradiance per unit area. This is modulated by two quantities. Solar energy absorbed by the earth received solar flux reflected solar flux s π r2 earth s π r2 earth x a s p r2 earth x 1 a a is the planetary albedo of the earth which is about 0 3. A solar flareup is headed for earth s magnetic field.

As well the total solar flux not solar flux per unit area must be determined. A on earth the solar flux is approximately 1 kw m 2. The geothermal heat flux generated by the earth interior natural terrestrial radioactivity and cosmic radiation which are all negligible relative to solar radiation. Essentially they re giant bubbles of gas and magnetic flux released from the sun with up to a billion tons of charged particles.

Assuming atmospheric loss of 3 db calculate the total output power of the sun in dbm. Pyramid terrestrial magnetic energy flux capacitor. Movement of solar energy through the earth atmosphere system. Then the total solar flux from the sun is divided by the surface area of a sphere that has a radius equal to the distance from the earth to the sun.

The separation of earth from the sun can be denoted r e and the mean distance can be denoted r 0 approximately 1 astronomical unit au. As a consequence the solar radiation influences many aspects of the earth. The atmospheric loss corrected flux stated above passes through every square meter of the surface of a sphere whose radius is the distance from sun to earth 93m miles. It is measured on a surface perpendicular to the rays one astronomical unit au from the sun roughly the distance from the sun to the earth.
