Measurement of spectral insolatons and processing the data for solar energy utilization (3rd report, influence of atmospheric factors on the total insolation ranged over the cutoff wavelength)

摘要

Under the condition of hemispherical incidence, a spectral-global pyranometer with a cutoff filter is used to measure the spectral property of insolation. In order to investigate the property classified into wavelength ranges covered by this means, I(λc) and H(λc) of radiation energy ranged over the cutoff wavelength were made from the measurements and the calculations by applying Bird's model which designated the spectral property of insolation.
