However, utilizing the full potential of the geodetic tools requires considerable scientific and technological development, with integration across the three main fields of geodesy, namely Earth´s geometry, gravity field and rotation being a major challenge. We would like to draw your attention to Session G04: ”The Global Geodetic Observing System: observing and interpreting mass transport in the Earth system” at the AGU Fall Meeting, December 10-14, 2007 in San Francisco, which will address this aspect of GGOS. The full session description is copied below. If you are working on observational, modeling and interpretation aspects relevant to the session, we would be pleased to see your abstract. Please, note that the deadline for abstract submission is September 6, 2007.

Traditionally, observations of the three pillars have been interpreted independently and inverted for mass changes particularly in the hydrosphere. Recently, attempts have been made to interpret observations of changes in geometry, gravity field, and rotation simultaneously. However, at the accuracy level of 10**(-9) or better, interactions between the Earth components (atmosphere, ocean, and solid Earth) as well as the three pillars (e.g., coupling of rotation and deformation) are relevant and an integrated theory consistent across the three pillars is required in order to process the observations, model the observed changes, and invert for model parameters describing the mass transport. The conveners invite papers addressing progress towards integrated data analysis, modeling and interpretation of observations of the three pillars on temporal scales ranging from free oscillations, Earth tides, meteorological and climatological processes to glacial loading, and on spatial scales from local to global studies. Aspects of particular interest are the combined processing of observations (e.g. gravity and displacements), improved forward modeling with Earth system models, and joint inversion of observations (e.g. displacements and rotation changes).
