The solar constant is a flux density measuring mean solar electromagnetic radiation per unit area.
The solar constant is measured at what altitude.
The solar constant is not a physical constant in the modern codat.
It is measured on a surface perpendicular to the rays one astronomical unit from the sun.
It is measured by satellite as being 1 361 kilowatts per square meter at solar minimum and approximately 0 1 greater at solar maximum.
Azimuth is measured in degrees clockwise from north.
Earth s solar constant a.
The angular height of the sun above the horizon.
Elevation is measured in degrees up from the horizon.
After correcting the readings for the remaining 1 of the atmosphere and earth sun distance a value of 1 912 gm cal cm 2 min has been determined for the solar constant.
Multiply your uncorrected solar irradiation by 2 to correct for the glass and also by 1 4 to correct for the atmosphere.
The spectra were measured with the bentham spectrometer.
Refers to the intensity of solar radiation that actually reaches earth s surface.

The sun s altitude refers to.
Cosine of solar zenith angle.
It is most accurately measured from satellites where atmospheric effects are absent.
Must be measured at aphelion.
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.
