Subject: [SLR-Mail] No.2623: GGOS Session at EGU From: ”Pearlman, Michael R. (Mike)” Dear Colleagues: We call your attention to the EGU sessions on: The Global Geodetic Observing System: Improving infrastructure for future science (see session abstract below.). This is an opportunity to present an update on the status and plans for the geodetic networks that provide the essential data for geodetic data products. In particular, it would be appropriate to have presentations and posters from the Geodetic Services (IGS, IVS, ILRS, IDS, IGFS, and the tide gauge network) and Core and co-location sites in operation or under development. This is one of the principle ways that we keep the community up-to-date on the infrastructure investment being made to provide the geodetic data. The deadline for abstracts is January 15 (see https://www.egu2020.eu/). We urge you to submit an abstract and join us at this years EGU meeting in Vienna. With best wishes for a Happy New Year, Mike Pearlman The Global Geodetic Observing System: Improving infrastructure for future science Convener: Kosuke HEKI Co-conveners: Detlef Angermann, Richard Gross, Michael R. Pearlman The Global Geodetic Observing System (GGOS) provides measurements of the time varying gravity, rotation, and shape of the Earth using geodetic and gravimetric instruments located on the ground and in space. These measurements need to be accurate to better than a part per billion in order to advance our understanding of the underlying processes that are causing the Earth´s rotation, gravity, and shape to change. Mass transport in the global water cycle, sea level and climate change, and crustal deformation associated with geohazards are examples of particularly demanding applications of geodetic and gravimetric measurements. All these measurements require a common reference with the same precision, like the Terrestrial Reference Frame and the Unified Height System. GGOS is designed to unite the individual observations and model into one consistent frame with the highest precision available. This session should be a platform for discussing improvements to global geodetic observing systems including multidisciplinary approaches as well as for single contributions with high precision in a global network.

The Global Geodetic Observing System: Improving infrastructure for future science

Convener: Kosuke HEKI

Co-conveners: Detlef Angermann, Richard Gross, Michael R. Pearlman

The Global Geodetic Observing System (GGOS) provides measurements of the time varying gravity, rotation, and shape of the Earth using geodetic and gravimetric instruments located on the ground and in space. These measurements need to be accurate to better than a part per billion in order to advance our understanding of the underlying processes that are causing the Earth's rotation, gravity, and shape to change. Mass transport in the global water cycle, sea level and climate change, and crustal deformation associated with geohazards are examples of particularly demanding applications of geodetic and gravimetric measurements. All these measurements require a common reference with the same precision, like the Terrestrial Reference Frame and the Unified Height System. GGOS is designed to unite the individual observations and model into one consistent frame with the highest precision available. This session should be a platform for discussing improvements to global geodetic observing systems including multidisciplinary approaches as well as for single contributions with high precision in a global network.
