GGOS Topical Meeting on the Atmosphere

Presentation
Since measurements from all space geodetic observation techniques (GNSS, DORIS,satellite altimetry, SLR, VLBI) propagate through the atmosphere, geodesy not only
determines the time-varying shape of the Earth, its gravity field and rotation, but is alsoable to detect spatio-temporal variations of the atmosphere. The analysis of geodetic
data provides important information about physical processes in the lower atmosphere(troposphere), middle atmosphere (stratosphere, mesosphere) and upper atmosphere(thermosphere, ionosphere/plasmasphere, magnetosphere; hereafter abbreviated asMIT). Understanding these processes is essential, for example, to identify risks ofextreme space weather events on critical infrastructure for daily life. The effect ofnatural and man-made hazards in the upper atmosphere also requires additional
research to deepen our understanding of coupling processes and to enhance warning
systems. In order to take full advantage of the technological developments in sensor
systems and observation techniques, a parallel and consistent further development ofdata analysis and combination methods is required. It is crucial to incorporate crosscutting expertise through the use of advanced geophysical modelling and newobservation concepts, as well as the application of data assimilation and machinelearning methods. For example, the intra- and inter-technique comparison andcombination of atmospheric delays and gradients at VLBI/GNSS/DORIS co-location sites
opens the possibility for a robust assessment that not only exploits the individual
strengths of the different observation techniques, but also sheds light on theinstrumental errors that manifest themselves in atmospheric delay estimates. This
integrated analysis leads to more reliable conclusions when studying geodesy-derived
integrated water vapour in the context of climate change. In the case of the upper(ionised) atmosphere, a current main objective is to investigate relevant processes inthe solar-terrestrial environment necessary to understand the spatial and temporalvariations of MIT key parameters such as electron density and vertical total electroncontent (VTEC) within the ionosphere/plasmasphere as well as neutral density in thethermosphere. Furthermore, leveraging novel geodetic observation techniques such as
GNSS reflectometry, recently onboard small satellites and CubeSats, enables us tocapture a wide variety of lower atmospheric and Earth surface data previously
inaccessible to conventional geodetic techniques. Integration of these developments
enhances our ability to monitor changes in the lower atmosphere over a broader
spectrum of parameters and spatial and temporal scales, while also improving ourunderstanding of its coupling with the Earth's surface.
In this context, the Global Geodetic Observing System (GGOS) of the International
Association of Geodesy (IAG) invites the geodetic and geophysical communities toparticipate in the GGOS Topical Meeting on the Atmosphere. The main objective is toestablish a multidisciplinary network of scientists to integrate geodetic and geophysicaltechnologies for comprehensive monitoring of the lower, middle, and upper
atmosphere and to identify existing and potential new related applications that
contribute to the dissemination and societal use of research results in this importantfield.
