The final version (V.19) of the total solar irradiance data from the SOlar Radiation and Climate Experiment (SORCE) Total Irradiance Monitor 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.

来自太阳辐射和气候实验(SORCE)总辐照度监测器的总太阳辐照度数据的最终版本 (V.19)已被释放。此版本包括更新至任务结束的所有校准，并提供 2003 年 2 月 25 日至 2020 年 2 月 25 日的辐照度数据。这些最终校准与最终数据产品一起呈现。提供了在轨操作时间表的概述以及与时间相关的不确定性的相关变化。还介绍了该仪器的科学亮点。其中包括建立一个新的、较低的 TSI 值；通过新的校准设施提高其他 TSI 仪器的精度；任何 TSI 仪器中最低的在轨噪声（对太阳变率具有高灵敏度）；任何在轨 TSI 仪器的最佳固有稳定性；得益于这些稳定、低噪声的测量，长期（17 年）的测量记录；首次报道在 TSI 中检测到太阳耀斑；以及两次金星凌日和四次水星凌日的观测。
