Paper Abstract

The unification and recognition of meteorological parameter is the key to achieve long-time scale climate monitor, which is solved by space radiation benchmark with high precision. A space-borne whiskbroom solar reflection spectrum radiation benchmark is proposed in this paper, and the standard value transmission is more simple and reliable, achieved by the pendulum sweep institution with high stability. Based on the pendulum sweep institution, the spectral response of transfer and sun spectral radiometer and hyper-spectral earth imager is calibrated in-flight. And the primary benchmark is space-borne cryogenic absolute radiometer, whose absolute measurement uncertainty is 0.02%. Besides, the absolute measurement uncertainty of transfer and sun spectral radiometer and hyper-spectral earth imager is analyzed respectively in this paper, and the absolute measurement uncertainty is 0.23% and 0.63%.
