Carrying a Fourier transform spectrometer, FORUM – short for Far-infrared Outgoing Radiation Understanding and Monitoring – will measure Earth’s outgoing radiation the far-infrared part of the electromagnetic spectrum that has never been measured from space before. Data from FORUM will provide unique insight into Earth’s radiation budget and how it is controlled, thereby fill in a missing piece of the climate jigsaw.
FORUM is ESA’s ninth Earth Explorer mission, selected after this video was recorded at the Earth Explorer 9 User Consultation Meeting in July 2019.
