Subject: G 2.1 session on GGOS at EGU2017

Dear colleagues,

the next EGU General Assembly will take place at Vienna 23rd-28th April 
2017 (see http://www.egu2017.eu).

We draw your attention to the session G 2.1: The Global Geodetic 
Observing System: Improving Today's Infrastructure for Tomorrow's Science


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.


You are invited to send an abstract for this session not later then 
January 11th, 13h CET.



Kind regards


Guenter Stangl, on behalf of the conveners of session G 2.1
