The article provides a general overview of the advances in optical methods for trace gas analysis. Recent advances in instrumentation and spectroscopic techniques have substantially expanded the feasibility of routine spectroscopic analysis of gaseous samples. Fourier-transform infrared measurements have become routine and automated systems are successfully providing time-sequenced, path-averaged emission data from agricultural operations, landfills, industrial facilities, and other large-area vapor emission sources. Great strides are also being made towards the development of airborne sensors that provide rapid wide-area surveillance and mapping capabilities.
