The Solar Constant For Earth Is

It is most accurately measured from satellites where atmospheric effects are absent.

The solar constant for earth is.

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. Which is the average solar intensity on the earth surface. The solar constant is the amount of solar radiation incidence that it is presently calculated as being 1 366 w m2. The solar constant is a measure of the power of a square meter of sunlight directly impacting on a perpendicular plane of space above the atmosphere of the earth and is considered to be a uniform value of 1 370 watts per square meter.

The solar constant is calculated by multiplying the sun s surface irradiance by the square of the radius of the sun over the average distance between the earth and the sun. We all know that the solar constant is 1350watt m 2 which is related to a unit surface perpendicular to the solar rays. The solar constant gsc is a flux density measuring mean solar electromagnetic radiation solar irradiance per unit area. Solar constant the total radiation energy received from the sun per unit of time per unit of area on a theoretical surface perpendicular to the sun s rays and at earth s mean distance from the sun.

6 7 1 0 8 w m 2 k 4. If the sun radiates as the black bodies the temperature at the surface of the sun will be the angle subtended by sun on the earth in suppose 0 53 o and stefan constant is σ 5. The earth receives solar radiation at a rate of 8 2 j cm 2 min 1.
