Active laser remote sensing is an emerging technique which has the unique capability of providing range-resolved measurements of gaseous and particulate species without day-night restrictions as is the case with certain passive sensing methods. The coherent output of a laser source can be used to interogate small areas, even from orbital altitudes, and pulsed lasers can be used to obtain high spatial resolution for concentration profiles by range gating the return signal. Laser measurements of chemical species can be made using differential absorption, DIAL, laser induced fluorescence, LIF, and by a new highly sensitive in-situ method resonance ionization spectroscopy, RIS. All these measurement techniques require tunable, narrow spectral bandwidth laser sources. Important atmospheric species suitable for ultraviolet or visible laser detection are: O3 SO2, and NO2, by DIAL methods, OH, NO, Na, K, Li, Ca and Ca+ by LIF, and the RIS method in conjunction with a mass spectrometer may prove to be a general point monitoring method for a wide variety of trace atmospheric molecules.
