MkIV Fourier Transform InfraRed (FTIR) Interferometer

Laboratory Studies and Atmospheric Observations Group (329H)

The JPL MkIV Interferometer is a Fourier Transform Infra-Red (FTIR) Spectrometer, designed and built at the Jet Propulsion Laboratory in 1984, to remotely sense the composition of the Earth's atmosphere by the technique of solar absorption spectrometry. This effort was born out of concern that man-made pollutants (e.g. chlorofluorocarbons, aircraft exhaust) might perturb the ozone layer. Since 1989, the MkIV Interferometer has participated in 3 NASA DC-8 polar aircraft campaigns, and has successfully completed 24 balloon flights. In addition, the MkIV Interferometer made over 1000 days of ground-based observations from many different locations, including McMurdo, Antarctica (1986), Fairbanks, Alaska (1997), and Esrange, Sweden (1999, 2000, 2002, 2003 & 2007).
