TELIS: TErahertz and subMMW LImb Sounder – Project summary after first successful flight
The TELIS instrument is a balloon-borne cryogenic three-channel heterodyne spectrometer for limb sounding of stratospheric trace gases. The instrument is flown together with the MIPAS-B Fourier-transform spectrometer of the IMK, Karlsruhe. TELIS was developed by a European consortium involving resea...
