The Smithsonian Astrophysical Observatory far-infrared spectrometer (FIRS-2) measures vertical mixing ratio profiles in the stratosphere from a balloon platform. The FIRS-2 is a high-resolution (0.004 cm{sup -1} unapodized) two-beam Fourier transform spectrometer which measures thermal emission in the regions 80-210 cm{sup -1} and 350-700 cm{sup -1}. Observations are made at various elevation angles, with absolute pointing referenced to a gyroscope- and accelerometer-stabilized single-axis platform. Molecules currently measured include OH, HO{sub 2}, H{sub 2}O, H{sub 2}O{sub 2}, O{sub 3}P, O{sub 2}, O{sub 3}, HCl, HF, HBr, HOCl, HOBr, CO, CO{sub 2}, N{sub 2}O, NO{sub 2}, HNO{sub 3}, and HCN. The measurements, the development of the relevant spectroscopy, and the application of the measurements to improving models of the photochemistry of the ozone layer are discussed.
