The present state of the art and new developments in the measurement of the concentrations of trace constituents in the atmosphere are outlined. Topics discussed include differential optical absorption spectroscopy, laser-induced fluorescence, tunable diode laser spectrometry, chemiluminescence, and Fourier transform infrared spectroscopy. Particular attention is given to developing a long-path diode array spectrometer for tropospheric chemistry studies, collisional effects in laser detection of tropospheric OH, advances in tunable diode laser technology for atmospheric monitoring applications, frequency modulation spectroscopy for chemical sensing of the environment, comparison of time and frequency multiplexing techniques in multicomponent FM spectroscopy, hydrogen peroxide and organic peroxides in the marine environment, use of chemiluminescence techniques in portable, lightweight, highly sensitive instruments for measuring NO2, NOx, and O3, and applicability of open-path monitors at Superfund sites.
