Absolute intensities for the center of the solar disc are given in the spectral range from 6389 to 12480 A. The observations are made in exactly the same manner as described in Z. Astrophys. 55:269(1962) for the visible part of the spectrum. The infrared ...

Prior to the mid 1970's there did not exist a method of making observations of solar irradiance to an absolute accuracy better than a few percent. Until the mid 1980s, even that low level of accuracy was only achievable through extraordinary effort because commercial pyranometers are known to drift in sensitivity by up to several percent per year under ...

There exists a growing need to improve the accuracy of measurement of the absolute solar flux within

A solar radiometer of novel design was used to measure the horizontal global solar irradiance. The instrument employs the principle of spectral selectivity of surfaces and gives directly an absolute determination of the solar irradiance. Construction is simple and the device is suitable for use in colleges.

Transmission spectra and extinction coefficients for different salt solutions have been measured. The effect of pond transparency on the performance of a district solar pond is also discussed.

Reduction of the earth's ozone layer, with a resultant increase in transmission of solar ultraviolet

This work investigates the formation of photoluminescence centres in high-transmission glass (HTG) doped with Cu2O and their capability to transform the solar spectrum by absorption/emission via Stokes-shifted PL into a more efficient spectrum for photovoltaic applications. Among the centres formed in HTG, both green photoluminescent Cu + and the ...

A radiometer was operated at the Mauna Loa Observatory during calendar year 1980 to estimate the spectral irradiance of the sun and its possible fluctuation in time near the peak of solar activity. Data were also acquired on seasonal trends of atmospheric transmissivity above the marine mixing layer in the central Pacific. Spectral irradiance remained c ...
