Temperature dependence of the water vapor continuum absorption in the 3–5 μm spectral region

Abstract Asymptotic line wing theory allows one to construct the line shape describing the frequency and temperature dependence of the self-broadened H2O continuum in the 3–5 μm spectral region obtained experimentally by CAVIAR and NIST. The H2O transmission functions are adequately described as well, using this line shape up to temperatures of ∼675 K and pressures of ∼10 atm.
