High-resolution Fourier-transform ultraviolet-visible spectrometer for themeasurement of atmospheric trace species: application to OH

A compact, high-resolution Fourier-transform spectrometer for atmospheric n ear-ultraviolet spectroscopy has been installed at the Jet Propulsion Labor atory's Table Mountain Facility (34.4 degreesN, 117.7 degreesW, elevation 2 290 m). This instrument is designed with an unapodized resolving power near 500,000 at 300 nm to provide high-resolution spectra from 290 to 675 nm fo r the quantification of column abundances The measurement technique used is spectral analysis of molecular absorptions of solar radiation. The instrum ent, accompanying systems designs, and results of the atmospheric trace atm ospheric hydroxyl column observations are described. (C) 2001 Optical Socie ty of America.
