The instrument consists of a solarimeter fitted with a hemisphere of heat-absorbing glass. By this means, a well-tried instrument, already widely used in meteorological stations for the measurement of total incident radiation, is converted into an instrument suitable for measuring photosynthetically
Knowledge of the photosynthetically active radiation is necessary in different applications dealing with plant physiology, biomass production and natural illumination in greenhouses. Nevertheless, as a result of the absence of widespread measurements of this radiometric flux, it is often calculated
