In recent time it has been shown that space geodetic techniques such as GPS, VLBI, DORIS, satellite altimetry, and the gravity missions Champ/Grace can give valuable information about the troposphere i.e., the neutral part of the atmosphere, and the ionosphere, usually expressed by TEC (total electron content) numbers. The potential for tropospheric/ionospheric 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. Abstracts are sought which present the results and the accuracy of tropospheric/ionospheric information and theoretical studies are encouraged that assess the requirements for the accuracy of the relevant parameters e.g., mapping functions, gradients and others. We are now at an exciting threshold at which accurate tropospheric/ionospheric estimates and retrievals from these techniques may significantly improve our understanding of the physical and dynamic behavior of weather and climate at various scales. The markedly different spatial and temporal capabilities for sensing the troposphere/ionosphere of the space-geodetic methods also pose great challenges to validation studies. Thus, comparisons with other measurements e.g., by WVR or radiosondes, and also comparisons of the results obtained by different space geodetic techniques are of great interest. Presentations with respect to the IAG project GGOS (Global Geodetic Observing System) i.e., dealing with the integration and combination of various techniques, are highly appreciated.
