The final version (V.19) of the total solar irradiance data from the (SORCE) has been released. This version includes all calibrations updated to the end of the mission and provides irradiance data from 25 February 2003 through 25 February 2020. These final calibrations are presented along with the resulting final data products. An overview of the on-orbit operations timeline is provided as well as the associated changes in the time-dependent uncertainties. Scientific highlights from the instrument are also presented. These include the establishment of a new, lower TSI value; accuracy improvements to other TSI instruments via a new calibration facility; the lowest on-orbit noise (for high sensitivity to solar variability) of any TSI instrument; the best inherent stability of any on-orbit TSI instrument; a lengthy (17-year) measurement record benefitting from these stable, low-noise measurements; the first reported detection of a solar flare in TSI; and observations of two Venus transits and four Mercury transits.
太阳辐射和气候实验卫星(SORCE)的总太阳辐照度数据最终版本(V.19)已发布。该版本包含截至任务结束时更新的所有校准数据,并提供了从2003年2月25日至2020年2月25日的辐照度数据。这些最终校准数据与最终数据产品一同呈现。文中还提供了在轨运行时间线概述以及随时间变化的不确定性的相关变化。此外,还介绍了该仪器的科学亮点。这些亮点包括确定了一个新的更低的总太阳辐照度值;通过新的校准设施提高了其他总太阳辐照度仪器的精度;所有总太阳辐照度仪器中在轨噪声最低(对太阳变化具有高灵敏度);所有在轨总太阳辐照度仪器中固有稳定性最佳;受益于这些稳定、低噪声测量的长达17年的测量记录;首次报告在总太阳辐照度中检测到太阳耀斑;以及对两次金星凌日和四次水星凌日的观测。
