The … Nettetlines and for the four strong water vapor lines at 22, 183, 325, and 380 GHz. The oxygen line widths and line coupling coef-ficients are from [33] and have been validated using ground-based radiometers [8], [9]. The line strengths for the 22- and 183-GHz water vapor lines are based on an analysis of the Stark-effect measurements described in [7].
