The Solar Constant Is Quizlet

It is measured by satellite as being 1 361 kilo watts per square meter kw m at solar minimum the time in the 11 year solar cycle when the number of sunspots is minimal and approximately 0 1 greater roughly 1 362 kw m at solar maximum.

The solar constant is quizlet. What is the unit of measurement for the sun s altitude. The term radiative forcing describes a measure of the effect of a climatic factor has on the balance between incoming solar radiation and outgoing infrared radiation. Must be measured at perihelion. It is most accurately measured from satellites where atmospheric effects are absent.

The solar constant a measure of flux is the amount of incoming solar electromagnetic radiation per unit area that would be incident on a plane perpendicular to the rays at a distance of one astronomical unit au roughly the mean distance from the sun to the earth. Must be measured at aphelion. Find the following statement s that correctly describe the stefan boltzmann s law. The solar constant is the amount of energy received at the top of the earth s atmosphere on a surface oriented perpendicular to the sun s rays at the mean distance of the earth from the sun.

How does a pv cell receive the highest average insolation. Refers to the intensity of solar radiation that actually reaches earth s surface. 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. Start studying solar constant.

The solar constant includes all types of solar radiation other than neutrinos not just the visible light. When solar irradiance is measured on the outer surface of earth s atmosphere 2 the measurements can be adjusted using the inverse square law to infer the magnitude of solar irradiance at one au and deduce the solar constant 3. Is about 0 5 calories per square centimeter per minute. The value of the constant is approximately 1 366 kilowatts per square metre.

The solar constant at the surface of the earth is 1 000 watts per square meter at sea level at solar noon. Earth s solar constant a. The sun s altitude is measured in the number of degrees above the horizon.
