Session ID#: 57947

Session Description:
The growing record of space-gravimetric and -geodetic data (GRACE, GNSS, radar altimetry, InSAR, VLBI, …) provides a new view on Essential Climate Variables such as tropospheric water vapor, water storage and ice mass changes, steric and barystatic sea level, sea surface winds, waves or sea ice extent. These observations have the advantage to be globally homogeneous, and independent from other data commonly used to develop and evaluate climate models.

Geodetic time series reveal a complex picture of natural climate variability, long-term climate change and anthropogenic modifications. Combined with other observations or reanalyses, they provide excellent tools to assess climate models and improve our understanding of land- and ocean-atmosphere interactions.

We invite contributions dealing with (1) detecting climate signals in geodetic observations (2) evaluating climate models using geodetic data, (3) creating long and consistent geodetic time series, (4) climate modelling of geodetically observable variables, and (5) the prospects of future missions.
