The Solar Constant Is Quizlet

Must be measured at perihelion.

The solar constant is quizlet.

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. 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. 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. How does a pv cell receive the highest average insolation.

The value of the constant is approximately 1 366 kilowatts per square metre. What is the unit of measurement for the sun s altitude. 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. Learn vocabulary terms and more with flashcards games and other study tools.

Start studying solar constant. Must be measured at aphelion. Earth s solar constant a. It is most accurately measured from satellites where atmospheric effects are absent.

Find the following statement s that correctly describe the stefan boltzmann s law. Refers to the intensity of solar radiation that actually reaches earth s surface. The portion of solar radiation that is partially blocked by ozone in the stratosphere is the sun according to wien s displacement law which one of the following objects emits the most intense electromagnetic energy at the shortest wavelength. The solar constant includes all types of solar radiation other than neutrinos not just the visible light.

Is about 0 5 calories per square centimeter per minute. 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 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.
