GGOS Topical Meeting on the Atmosphere

October 7, 2024 - October 9, 2024

GGOS serves as an integrating framework for all components of the International Association of Geodesy (IAG), providing a clearinghouse for geodetic expertise and fostering interdisciplinary research. A current challenging topic is the modelling of spatio-temporal variations of the atmosphere (troposphere, stratosphere, mesosphere, thermosphere, ionosphere/plasmasphere) and the magnetosphere using geodetic and geophysical observations. Several colleagues are making great progress in this field, and therefore, GGOS is convening this meeting to bring together all these colleagues to share common research points and to identify new topics for study. The scope of the meeting also includes the participation of colleagues from the International Association of Geomagnetism and Aeronomy (IAGA), with the main objective of establishing a multidisciplinary network of scientists to integrate geodetic and geophysical technologies for comprehensive monitoring of the atmosphere and categorise existing and potential new related applications that contribute to the dissemination and societal use of research results in this important field.

Contributions on the following topics are welcome:

  • – Integration/combination of geodetic and geophysical technologies for comprehensive monitoring of the atmosphere.
  • – Application of machine learning techniques to the analysis of geodetic and geophysical observations relevant for the atmosphere.
  • – Intra- and inter-technique comparison and combination of atmospheric delays and evaluation against numerical weather models.
  • – Atmospheric ties to improve reference frames and coordinate solutions.
  • – Analysis of ionospheric disturbances and their contribution to tsunami early warning systems or other geohazard monitoring.
  • – Recent progress, current understanding, and future challenges in MIT (magnetosphere, ionosphere/plasmasphere, thermosphere) research, with focus on the coupling processes.
  • – Combination of measurements from space geodetic observation techniques including radio occultations with observations from solar missions to produce global and regional high-resolution and high-precision models of MIT key parameters such as VTEC, electron density and neutral density.
  • – Atmospheric data using newly developed geodetic observational methods and deployed satellites, such as those involved in GNSS reflectometry missions, and validating the results.
  • Development of modelling approaches for nowcasting and forecasting of MIT key parameters, e.g. by applying suitable assimilation methods and machine learning algorithms.
  • Definition of potential essential variables to characterise the lower, middle, and upper atmosphere.

Meeting Logistics

The meeting will be held over three days (October 7-9), with daily sessions between 8:30 and 17:00 and a lunch break between 12:30 and 14:00. The morning sessions will be devoted to oral presentations, while the afternoon sessions will be devoted to posters and panel discussions. In the two days following (October 10-11) the GGOS Topical Meeting, the GGOS Days 2024 will take place at the same location. Participants of the GGOS Topical Meeting are also welcome to attend the GGOS Days 2024more information here.
