3. Solar Radiation
sun is a hydrodynamic spherical body –
generating energy by the process of
thermonuclear fusion.
Temperature of the interior of the sun is
estimated at 8X10^6 -40X10^6 K,

4. EXTRATERRESTRIAL &TERRESTRIAL RADIATIONS
Solar radiation incident on the outer
atmosphere of the earth is known as
Extraterrestrial Radiation
 Iext=Isc[1+0.033cos(360n/365)] W/m2

5. EXTRATERRESTRIAL &TERRESTRIAL RADIATIONS
Solar radiation incident on the outer
atmosphere of the earth is known as
Extraterrestrial Radiation
 Iext=Isc[1+0.033cos(360n/365)] W/m2
Solar radiation that reaches earth surface after
passing through the earth‟s atmosphere is known
as Terrestrial Radiation.
