Solar Constant
The average amount of solar radiation reaching a planet; usually expressed in watts (energy per unit time) per square meter. For Earth, the solar constant equals 1,372 W/m2.

SOLAR CONSTANT
The solar constant is amount of solar power flux (energy flow) that passes through the Earth's orbit. The currently-accepted estimate of the solar constant is 1,367 Watts/m2.
solar constant
The total radiant energy received vertically from the Sun, per unit area per unit of time, at a position just outside the Earth’s atmosphere when the Earth is at its average distance from the Sun.
[15] The solar constant is about 1.3 kilowatt/m2 and one (small) calorie equals 4.18 joule.
solar constant The rate at which solar radiation is received outside the earth's atmosphere on a surface normal to the incident radiation and at the earth's mean distance from the sun.
Since sunspots are dark it might be expected that more sunspots lead to less solar radiation and a decreased solar constant. However, the surrounding areas are brighter and the overall effect is that more sunspots means a brighter sun.
The ACRIM instrument package monitored the total energy output of the Sun (often referred to as the "Solar Constant") throughout the mission with great precision.
We can describe the amount of the Sun's energy reaching Earth as 1 solar constant. The average distance from the Sun to Earth is 149,597,870.
This is known as the solar constant. This combined with the elliptical orbit results in large temperature fluctuations. The lowest temperature recorded was in northern hemisphere winter -124 C. The highest recorded temperature was -31 C.
The solar constant is the irradiance of the Earth by the Sun. The value is 1.35 KW m-2.
The integrated emission of energy is given by the area of the outer smoothed curve (4), and the conclusion from this one holograph is that the " solar constant " is 2.54 calories.
Although it has long been assumed to be a constant source of energy, recent measurements of this solar constant have shown that the base output of the Sun can vary by up to two tenths of a percent over the 11-year solar cycle.
Compare solar constant. inspection (NASA Thesaurus) The process of measuring, examining, testing, gaging, or making other determinations with respect to materials, products, services, systems, or environments.
