Abstract
In order to support the analysis of potential long-term trends in the Sun’s variability and trace the WRR ground calibration ratio to the measurement on the satellite. We established the total solar irradiance (TSI) calibration model in orbit for the new generation of solar radiation monitor on the FY-3E satellite. First, we measured the non-equivalence of the instrument, and the air to vacuum ratio of the SIAR radiometer is 0.9958-0.9973. Then, we established the temperature correction model for the important parameters, such as the aperture area, the standard voltage and the heating wire resistance. Finally, we calibrated the SIAR with the world radiation reference (WRR) and traced the ground calibration result to the measurement on the satellite. The end-to-end calibration ratio is 0.9991-1.0006, and the uncertainties for three channels are all better than 0.08%.
