Watkins Subject: AGU Special Session - Gravity Field Modelling Colleagues - we call your attention to the following Fall AGU special session: G05: Gravity Field Observations and Models Conveners: Michael Watkins, Jet Propulsion Laboratory (JPL), M/S 238-638, 4800 Oak Grove Drive, Pasadena, CA 91109, Office 818-354-7514, Fax 818-393-4965, E-mail mmw@cobra.jpl.nasa.gov, Christoph Reigber, GeoForschungsZentrum Potsdam (GFZ), Div. 1: Kinematics and Dynamics of the Earth, Telegrafenberg A17, 14473 Potsdam, Germany, Office 49-331-288-1100, Fax 49-331-288-1111, E-mail reigber@gfz-potsdam.de Session Description: The CHAMP and GRACE Missions, launching in 2000 and 2001, respectively, will enable significant improvements in global gravity field models. The precision of the measurements from these missions places unprecedented requirements on the dynamic, measurement, and even computational models used in the gravity field determination. In some cases, innovative representations other than the conventional coefficients of a spherical harmonic expansion may be preferable. Stringent requirements are also placed on ancillary models used to determine or interpret the gravity models including ocean tides, atmospheric pressure, barotropic ocean signals, and others. Finally, full exploitation of the gravity data benefits from combination with other data types, including laser/radar altimetry, vertical rebound measurements, and more. In this session, we invite contributions on the general topic of gravity modelling, with emphasis in the following areas: 1) on the status and capabilities of future gravity missions 2) on the current state, plans, and/or techniques for high precision gravity model determination and representation, including treatment of ancillary geophysical fields 3) on techniques for combining gravity with other data types for improved interpretive science.
