Abstract : A description is given of the development and performance of instrumentation for the continuous measurement of solar and sky ultraviolet radiation as received on a horizontal surface from sun and sky (pyranometer) as well as in normal incidence from the sun (pyrheliometer). Sources of errors such as change in air mass (filter-weighting factor) and environment (transient response) are discussed, and areas of needed improvement are indicated. (Author)
