title: Solar spectral measurements in the terrestrial environment.
abstract: Calibrated terrestrial solar spectra are presented from measurements made with a new instrument under diverse atmospheric conditions. The atmospheric turbidity and the amount of cloud cover were recorded simultaneously with the spectra. The two main objectives of this paper are: to provide spectral data of high enough resolution and on a broad enough wavelength scale to make the data useful for studies where spectral position and bandwidth are critical factors; and to provide in one location sets of spectra that illustrate several atmospheric effects on the solar spectrum. Interpretation of the spectra is primarily left to the reader. Direct normal, diffuse, and global spectra are illustrated.
