2009 Annual Science Report
NASA Jet Propulsion Laboratory - Titan Reporting | JUL 2008 – AUG 2009
Task 2.1.2 Atmospheric State and Dynamics
An understanding of the structure of the Titan atmosphere provides the context for the formation of complex organic compounds in the atmosphere.
Co-Investigators Mark Richardson and Claire Newman have improved the realism in the TitanWRF simulation of the Titan stratosphere. The Ls=270 (southern summer solstice) model results shown in Figure 1 compare well with recent Cassini temperature observations. They also are making use of the Laboratoire Meteorologie Dynamique (LMD) 2D Titan GCM (output from which is available online at http://web.lmd.jussieu.fr/titanDbase) to develop a reference atmospheric model. Results from this latter model are shown in Figure 2.
