SOLAR RADIATION MEASUREMENT ON SHENZHOU-3 SPACECRAFT

摘要: 2002年3月至9月间,用3台太阳辐照度绝对辐射计（SIAR）组装的太阳常数监测器在神舟3号飞船轨道舱上测量了太阳辐照度.改进了SIAR辐射计的锥腔结构,把电加热丝埋在薄锥腔壁中间,提高了绝对精度.采用了用宽视场辐射计飞船在轨运动中太阳扫过其视场期间进行测量的方法,测量值与美国EOS上ACRIM III测量数据的最大偏差在0.2%以内.Abstract: TSI （Total Solar Irradiance） has been measured by solar constant monitor, which is composed of three SIAR （Solar Irradiance Absolute Radiometer）, on board of Shenzhou-3 spacecraft from March to September in 2002. The structure of the cavities has been improved, the substitution winding being embedded in the wall of each SIAR’s cavities, so the absolute precision is heightened. Solar irradiance was measured when the sun scans over the field of view of each absolute radiometer respectively. The data is coincident with the data simultaneously measured by EOS/ACRIM in 0.2%.
