Scientific aims: • To develop new tuneable diode laser components and techniques, and incorporate them into instruments for environmental measurements. • To determine high-resolution infrared spectra of compounds of environmental interest.
Highlights of JETDLAG current scientific results The technique used in JETDLAG is an infrared absorption spectroscopy with tuneable diode laser light sources whose narrow line widths offer the possibility of high selectivity for a large number of interesting compounds in the atmosphere. Much effort has been devoted to improving the sensitivity (a novel frequency modulated technique has been developed) and to multiplexing the instruments so that they can make simultaneous measurements of several pollutant concentrations. Instruments have been developed for use on aircraft and for laboratory and field measurements.
