As a consequence, significant errors can occur in the measurement of individual instantaneous radiation values. A simple model for the dynamic response of thermal radiation instruments is developed. The model suggests that the readings of a thermal radiometer can be corrected using the rate of change of the indicated reading and the instrument time constant. It is shown experimentally that the error correction applied to the signal of a thermal pyranometer yields almost identical results as a photovoltaic pyranometer. The error correction allows conventional thermal radiation instruments to be used for instantaneous radiation measurements.
