Allison, M., D.H. Atkinson, M.K. Bird, and M.G. Tomasko, 2004: Titan zonal wind corroboration via the Huygens DISR solar zenith angle measurement. In International Workshop on Planetary Probe Atmospheric Entry and Descent Trajectory Analysis and Science, ESA SP-544. A. Wilson, Ed. ESA Publications Division, ESTEC, pp. 125-130.

The in situ measurement of the vertical profile of Titan's zonal wind is a major objective of the Huygens probe mission, as specifically addressed by the Doppler Wind Experiment (DWE). It now appears likely that an independent, if somewhat less accurate corroboration of the zonal wind retrieval will be afforded by the measured variation of the solar zenith angle Z from the Huygens Descent Imager/Spectral Radiometer (DISR) throughout the course of the probe's atmospheric descent. The analyzed synergism of the DWE and DISR solar-Z measurements should provide an enhanced evaluation of the Titan atmospheric circulation. resolved measurements of the wind itself. The Huygens Doppler Wind Experiment (DWE) is specifically dedicated to providing a highly resolved measurement of the vertical profile of the zonal wind at the probe's south-equatorial entry site to within an accuracy better than ∼1 m/s [15]. This will provide a "ground-truth" benchmark for thermal wind mapping of Titan's global circulation from the Cassini Composite Infrared Spectrometer [16] as well as cloud-tracked wind measurements from the Cassini Imaging Science.
