A Tunable Diode Laser Absorption Spectrometer (TDLAS) is an airborne or ground-based in situ optical spectrometer. TDLAS measures the wavelength-dependent absorption of light to determine the concentration of various trace gases. It can also determine the gas species' temperature, pressure, velocity, and mass flux when possible. TDLAS has a typical time resolution of 1 second.
