The measurements of the water vapor continuum were analyzed using infrared cavity ringdown spectroscopy (CRDS) at frequencies of 931.002, 944.195 and 969.104 cm-1. The experiments uses a continuous-wave CO2 laser and an acousto-optic modulator to create laser pulses which are injected into a 100 cm long near-confocal ringdown cavity. It is found that the far wings of water vapor lines are the primary agent responsible for the water vapor continuum.
