Water vapor lines at 227.8 and 254.0 cm(-1) were discovered in Titan's stratosphere from observations taken with the ISO Short Wavelength Spectrometer (SWS) in the grating mode. Line strengths are ~ 8 times the 1sigma statistical noise level, with a resolving power ~ 2000. A recent photochemical model [1] predicts correct H2O/CO2 line strength ratios, provided the actual H2O abundance is 0.4 that of the model. Using this scale factor of 0.4, we infer a water influx of 0.8 - 2.8 x 10(6) mol cm(-2) s(-1) at Titan, referred to an altitude of 700 km. This is comparable to the H2O influx of 0.3 - 5.0 x 10(6) mol cm(-2) s(-1) found at Saturn [2]. We discuss ice dust production and transport mechanisms in the Saturn system that might give rise to such values. References: [1] LARA, L. M., et al. (1996), J. Geophys.
