, and R.H. Tipping, 2008: Water-vapor continuum absorption in the 800-1250 cm-1 spectral region at temperatures from 311 to 363 K. J. Quant. Spectrosc. Radiat. Transfer, 109, 2291-2302, doi:10.1016/j.jqsrt.2008.03.004.About 200 pure water-vapor spectra covering the region from 800 cm-1 to 3500 cm-1 were recorded with resolution of 0.1 cm-1 at temperatures 311, 318, 325, 339, 352, and 363 K using a 2 m base White cell coupled to the BOMEM DA3.002 FTIR spectrometer. The water-vapor pressure varied from 28 to 151 mbar (21 to 113 torr). Under these conditions, the continuum absorbance is quite measurable with the available path lengths up to 116 m. A program was developed for spectral processing that calculates, fits, and removes ro-vibrational structure from the spectrum. The spectra obtained were used to retrieve averaged and smoothed binary absorption coefficients over the region from 800 cm-1 to 1250 cm-1. Our continuum data extrapolated to room temperature are in reasonable agreement with the MT-CKD continuum model. But at higher temperatures the MT_CKD model provides very low values, which are up to 50% less than those experimentally measured.
