Measurements and interpretations of the water vapour continuum at near infrared wavelengths

The self and foreign water vapour continuum have been derived using high spectral resolution laboratory-based Fourier transform spectrometer measurements of pure water vapour and mixed with air between 1200 and 8000 cm-¹. These measurements were conducted over a temperature range of 296-351 K and a vapour pressure range of 12-274 mb. Over this pressure range it was found that the optical depth of the self continuum had a pressure squared dependence and a strong negative temperature dependence. The foreign continuum optical depth scaled with the product of the vapour and air pressure and had a weak negative temperature dependence.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
