Subject: G 2.1 session on GGOS at EGU2017<br>
<br>
Dear colleagues,<br>
<br>
the next EGU General Assembly will take place at Vienna 23rd-28th
April 2017 (see <a class="moz-txt-link-freetext" href="http://www.egu2017.eu">http://www.egu2017.eu</a>). <br>
<br>
We draw your attention to the session G 2.1: The Global Geodetic
Observing System: Improving Today's Infrastructure for Tomorrow's
Science<br>

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.<br>
<br>
<br>
You are invited to send an abstract for this session not later
then January 11th, 13h CET.<br>
<br>
<br>
<br>
Kind regards<br>
<br>
<br>
Guenter Stangl, on behalf of the conveners of session G 2.1</span><span
