Crds spectroscopy
Webdown spectroscopy (CRDS) technique. This analyzer was flown without a drying system or any in-flight calibration gases. Water vapor corrections associated with dilution and pressure-broadening effects for CO2 and CH4 were derived from laboratory experiments employing measurements of water vapor by the CRDS analyzer. Before the campaign, the WebCavity ringdown spectroscopy (CRDS), based on de-tecting the rate of decay of light exiting a high-finesse optical resonator, is becoming a convenient means of trace-gas analysis.1 CRDS systems have evolved from pulsed laser sources coupled into linear resonators to more-complex cavity-locked systems employing ring
