Abstract

The design and operation of a multipurpose instrument for the measurement of solar radiation at ground level is presented. The instrument measures insolation in seven spectral bands from 427.8 nm to 940.0 nm. The field of view of the photometer is 3° and the basic mode of operation is that of scanning the sky in a series of almucantars. In addition, the instrument measures the direct beam of the sun at fifteen minute intervals. The basic data, therefore, consists of both direct and diffuse components of insolation which can be synthesized to yield the sum total falling on a surface of arbitrary orientation. The detection mode will allow a basic stability in the measurement of ±2% and the instrument module is portable and suitable for remote siting. Control of the instrument is accomplished with a dedicated minicomputer, and data logging on digital magnetic cassette tape allows unattended operation for periods of 1-2 weeks.
