Space geodetic techniques such as GNSS (both ground and LEO based), VLBI, satellite altimetry, or the GPS Radio Occultation missions with global coverage (CHAMP/GRACE, Formosat-3/COSMIC or TerraSAR-X) provide valuable atmospheric information about both, the lower neutral atmosphere (troposphere and stratosphere), and the ionosphere as well. The potential for atmospheric sensing using these techniques has improved considerably over the last few years as a result of technological advances, larger ground networks and developments of appropriate models and algorithms. Contributions are sought which present recent sounding results and report on achieved improvements of the accuracy and temporal and spatial resolution of derived tropospheric, stratospheric and ionospheric parameters. Theoretical studies that assess requirements for the accuracy of the relevant parameters are especially encouraged.
We are now at an exciting threshold at which accurate atmospheric estimates and retrievals based on these techniques may significantly improve our understanding of the physical and dynamic behaviour of weather and climate, and space weather at various scales. On the other hand, high-precision geodetic analysis is requiring more and more sophisticated models to improve strategies for the modelling of atmospheric delays and perturbations. Corresponding contributions and furthermore, presentations with respect to the IAG project GGOS (Global Geodetic Observing System) about the integration and combination of atmospheric parameters from various techniques are highly appreciated.
