A crystal pyrradiometer


A pyrradiometer, which is a single sided instrument for measuring both long and short wavelength radiation, has been developed. The instrument is protected from the wind by polythene hemispheres, and usesY-cut quartz crystals as temperature sensors. The output is in terms of frequency, the sensitivity being 13.1 Hertz (mW)−1 cm−2.
