GGOS Session

We would like to draw your attention to our GGOS session G007:
Geodetic Standards for Improved Accurate and Consistent Earth Observation Products from the Global Geodetic Observing System Techniques
GGOS Session Description:
Ensuring up-to-date geodetic standards is essential for analyzing observational data and delivering accurate and consistent products interoperable in both geodetic and other earth sciences. Several organizations are interested and cooperate on achieving new and improved standards: so, GGOS is developing the upcoming international height reference framework, IAU/IUGG/IAG have resolutions recent and underway, and IERS is updating its 2010 Conventions.
We invite discussions of revisions to standards like status of the update of fundamental constants and models for tides, geopotential and Earth rotation, and topics including but not limited to main geodetic techniques such as VLBI, GNSS, SLR, LLR, DORIS, altimetry, and gravimetry, as well as their co-location in ground and space, infrastructure improvement, or RFI protection. The session also welcomes discussions on geodetic data bases and products, their better exploitation, or meeting societal needs through timely applications to, e.g., geohazards monitoring, geodetic space weather research or artificial intelligence for geodesy.

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.
