Space geodetic techniques such as GNSS (both ground and LEO based), VLBI, satellite altimetry, the gravity missions CHAMP/GRACE, or the recently launched Formosat-3/COSMIC mission provide valuable atmospheric information about both, the lower neutral atmosphere (troposphere and stratosphere), and the ionosphere as well. The potential for atmospheric sensing with these techniques has improved considerably over the last few years as a result of technological advances and developments of appropriate models and algorithms. Contributions are sought which present recent sounding results and report on achieved improvements of the accuracy of derived tropospheric, stratospheric and ionospheric parameters. Theoretical studies that assess requirements for the accuracy of the relevant parameters are especially encouraged. First results from the Formosat-3/COSMIC mission are also highly welcome.
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. The markedly different spatial and temporal capabilities of the space-geodetic methods for sensing the atmosphere also pose great challenges to validation studies. Thus, comparative studies using ground based techniques, such as WVR or radiosondes for the neutral atmosphere and vertical incidence sounding of the ionosphere are invited. Furthermore, studies on space geodetic techniques are highly appreciated, in particular presentations with respect to the IAG project GGOS (Global Geodetic Observing System) dealing with the integration and combination of various techniques.
