This paper presents results from an intercomparison of self-broadening coefficients and intensities of approximately 440 of the strongest water vapour lines in the spectral region 5000-5600 cm(-1). Line parameters retrieved and reported recently by two scientific groups, both using Fourier transform spectroscopy, are compared with parameters taken from the HITRAN-2008 database and with theoretical linelist BT2 This comparison has revealed marked systematic differences in the self-broadening coefficients (up to 20%) and to lesser degree in the line intensities (up to 6%) between different sources.
