Solar Radiation Measurement Instrumentation

Abstract

A pyranometer for measuring sun and sky radiation on a horizontal surface in selected broad spectral bands was developed. A thermoelectric-type sensor was modified to permit use of hemispheric glass filters of practical size. Desired spectral bands can be selected by using two or more units with differing sharp cut-offs on the ultraviolet side of their pass bands but nearly identical transmission limits on the infrared side and subtracting the output of the narrower bands from the longer. The new equipment is described and its design philosophy and performance are discussed. A mount providing for altitude and azimuth adjustment, and provision for as many as three different hemispheric filters on each sensing unit, make the equipment suitable for a variety of applications.
