The design and scientific objectives of the SAFIRE-A (spectroscopy of the atmosphere using far infra-red emissions-airborne) instrument are described. The instrument exploits technical developments achieved during the development of the SAFIRE concept for space. These include an interferometer of compact design with spectral resolution 0.004 cm-1, and narrow-band filters (2 cm-1 wide) to reduce photon noise. The instrument is capable of detecting ozone and trace gases that affect ozone depletion, for example OH, HO2, H2O2, HOCl, HCl, ClO, HF, HBr, and also H2O. The measurements include column content above the aircraft (above 20 km) and height resolved abundances at lower altitudes. The first flight is scheduled for July 1996.
