Scientific paper

We propose here to take a major step forward in the study of Titan's atmosphere and surface by doing a partial survey of the detectable features at red and NIR wavelengths, probing from 100km to the surface. In cycle 2 of the HST, 8 images of Titan were obtained with the Planetary Camera; in the F850LP, several small- scale features, that could be either on the surface or in the lower atmosphere, or both, were clearly seen (Smith et al., 1992). The 1992 images proved the ex- istence of trackable features; however, the photometry is inaccurate because of the image reconstruction difficulties with WFPC1. A partial orbital revolution of Titan will now be observed, with several filter sets, at several intervals. We will identify, track, and characterize all surface and near-surface features using five filters chosen to sound the altitude range. Methane band filters are particularly useful in providing high contrast and accurate altimetry. Features tidally locked with Saturn are likely to be on the surface. Features not synch- ronous with Saturn are probably atmospheric. Wind vectors can be derived from them. A three-dimensional map of observed features, and their velocity vectors, will be produced, using time history and limb-darkening information. The final product will include a new global circulation model for Titan, a revised atmos- pheric scattering model and a surface map.
