To celebrate the 5-year anniversary of the successful launch of TROPOMI on 13 October 2017, a celebratory meeting was held in Taormina, Italy from 10-14 October 2022 to highlight the mission heritage and achievements. It was an excellent occasion to bring teams together from all stages of mission planning, instrument construction, testing, calibration, flight operations to algorithm development, deployment and validation. You can revisit this meeting and view all the presentations via the S5P 5-years meeting website hosted by ESA.
