Cosine Response
Spectral response estimate of Apogee silicon-
cell pyranometers. Spectral response was
estimated by multiplying the spectral response
of the photodiode, diffuser, and adhesive.
Spectral response measurements of diffuser and
adhesive were made with a spectrometer, and
spectral response data for the photodiode were
obtained from the manufacturer.
