GGOS Topical Meeting on the Atmosphere
2024-10-07 - 2024-10-09 | Wissenschaftetage im Bildugsforum – Potsdam, Germany, Am Kanal 47, Potsdam, 14467, Germany
Topics Meeting Logistics Dates Registration Abstract Submission Travel Award
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.
