Final (V.19) TSI data products from the SORCE/TIM (SOlar Radiation and Climate Experiment/Total Irradiance Monitor) have been released (available from lasp.colorado.edu/home/sorce/data/tsi-data/ and disc.gsfc.nasa.gov/datasets?page=1&keywords=sorce), completing the instrument’s 17-year measurement record of the net radiant energy incident at the Earth and powering the Earth’s climate system. The many innovations in this new instrument improved the accuracy of the TSI measurement record and propagated that to other TSI instruments, leading to the establishment of the now-accepted TSI value of 1361 Wm−2. Other science results include the first detection of a solar flare in TSI and the measurements of two Venus and four Mercury planetary transits across the solar disk. The Mercury transits are indicative of expected signals of an Earth-like exoplanet transiting a Sun-like star.
