Abstract：In order to ensure the accurate and reliable photosynthetically active radiation measurement, sensitivity calibration of photosynthetic active radiation pyranometer is required. Two kinds of sensitivity traceability system are proposed. Calibration methods with spectroradiometer and standard photosynthetic active radiation pyranometer are described in detail respectively. The results show that, the difference between using standard photosynthetically active radiation pyranometer and spectral radiometer is within 5% which meets the need.
