First CRDS-measurements of water vapour continuum in the\ud 940nm absorption band

By L. Reichert, M. Andres Hernandez, J. Burrows, A. Tikhomirov, K. Firsov and I. Ptashnik

Abstract

Measurements of near-infrared water vapour continuum using continuous wave cavity ring down spectroscopy (cw-\ud CRDS) have been performed at around 10611.6 and 10685:2 cm1. The continuum absorption coefficients for N2-\ud broadening have been determined for two temperatures and wavenumbers. \ud These results represent the first near-IR continuum laboratory data determined within the complex spectral environment in the 940nm water vapour band and are in reasonable agreement with simulations using the semiempirical CKD formulation
