  The ESO workshop "Ground-based thermal infrared astronomy" was held on-line
October 12-16, 2020. Originally planned as a traditional in-person meeting at
ESO in Garching in April 2020, it was rescheduled and transformed into a fully
on-line event due to the COVID-19 pandemic. With 337 participants from 36
countries the workshop was a resounding success, demonstrating the wide
interest of the astronomical community in the science goals and the toolkit of
ground-based thermal infrared astronomy.
