Earth's solar constant
Webthe sun at the earth, per square metre is called the solar constant and is approximately 1370 watts per square metre (W m-2). The solar constant actually varies by +/- 3% … WebThe solar constant is a measure of the amount of radiant energy reaching the earth's outer atmosphere from the sun. More precisely, it is equal to the rate at which solar radiation falls on a unit area of a plane surface at the top of the atmosphere and oriented at a perpendicular distance of 9.277 x 10 7 mi (1.496 X 10 8 km) from the sun.
