The Evans-Newkirk Photographic sky photometer, the Eppley Angstrom Pyreheliometer, the Eppley Normal Incidence Pyrheliometer, the Block Interferometer spectrometer and the Harvard-Evans Visual Sky Photometer were evaluated to determine the equipment and methods which produce the greatest precision in measuring solar irradiance. This evaluation consisted of theoretical analyses and laboratory tests as well as field use of the instruments. The report describes the procedures which were used, the auxiliary equipment which was found best and the precision which was measured with the field tested instruments. Author
