Water vapor absorption comprises both the effect of spectral line absorption and the broadband so-called continuum absorption (e.g. Shine et al., 2012). Depending on the atmospheric state and the choice of continuum model, up to 6% of the clear-sky water vapor absorption can be attributed to the continuum (Paynter and Ramaswamy, 2011). In spite of decades of extensive studies, the role of water dimers (WD) in the atmospheric radiation budget is still controversial.

The pure water-vapor continuum absorption in the 2.88 to 5.18μm spectral region has been measured using a Fourier-transform infrared spectrometer at a resolution of 0.1cm−1. The water vapor continuum absorption spectrum is retrieved using the known absorption in the 2500 cm−1 region as a reference point. It is shown that the continuum absorptions in four windows differ Water vapor continuum absorption coeffi cient C (v) at T= 296 K as a function of frequency v and wavelength X in the 8-30-gm region; most recent data of Burch 21,24 (-).

It has been suggested that it results from the accumulated absorption of the distant wings of lines in the far infrared. Approximately 98% of the water vapor absorption occurs in near‐infrared and infrared Determination of the water vapor continuum absorption from 0.35 to 1 THz is reported. The THz pulses propagate though a 137 m long humidity-controlled chamber and are measured by THz time-domain spectroscopy (THz-TDS).

We present experimental and theoretical studies of medium infrared absorption by pure water vapor. Measurements have been made in the 1900-2600 /cm and 3900-4600 /cm regions, for temperatures and pressures in the 500-900 K and 0-70 atm ranges, respectively. IR absorption by CO 2 at 14.7 μm sets the long wavelength limit of the infrared atmospheric window together with absorption by rotational transitions of H 2 O at slightly longer wavelengths. The short wavelength boundary of the atmospheric IR window is set by absorption in the lowest frequency vibrational bands of water vapor.
