Abstract
Standard values of the solar constant and extraterrestrial solar spectrum are reviewed. In the visible and near uv, this listing of average irradiance over 100-A bandwidths at 50-A intervals was found to be inadequate for many applications. A more detailed spectrum obtained from solar scans with a Perkin-Elmer, Model 112 monochromator was found to give sufficient detail. A normalization program was developed to make the Perkin-Elmer curve agree with the standard curve. Values of extraterrestrial solar spectral irradiance at 1-A intervals in the range 3000-6100 A have been derived. The results are presented in tabular form and as spectral charts.
