Welcome Letter and Objectives of the GGHS2016
Greece September 19-23, 2016
During the last decade, geodesy in general and gravity field modelling in particular, have experienced a notable swing in both their recognition and end-product use by many scientific disciplines. This was mainly due to the advent of the dedicated satellite gravity missions CHAMP, GRACE and GOCE, which have brought new insights to both the static and time-variable representations of the Earth’s gravity field. Future satellite missions such as GRACE-Follow On and the generation beyond, complemented by enhanced processing technologies, shall substantially improve this knowledge with further increased spatial and temporal resolution. Alongside came advancements in traditional terrestrial, airborne and shipborne gravity instrumentation which offer considerable improvements in gravity networks and the monitoring of gravity variations. Moreover, the continuous availability of altimeters on-board satellites and the improvements in the representation of the marine geoid have provided higher accuracies to shorter spatial scales of the ocean topography and circulation. The collocated use of the new datasets and models offered by gravity-field related research can improve the knowledge of the Earth system, its sub-systems, coupling processes among them, which are important indicators for climate change. They provide the breadboard for innovative investigations of the solid Earth giving new details of crust and mantle and their variation in time. Finally, they can lead to the linkage of local vertical datums to a global one, the latter being fundamental for monitoring sea level variations, as well as engineering and hydrological and cryospheric studies.
The GGHS2016 “Gravity, Geoid and Height Systems 2016” Meeting is the first Joint Commission2 and IGFS Symposium co-organized with GGOS Focus Area 1 “Unified Height System”. It will take place in Thessaloniki, Greece September 19-23, 2016 at the premises of the Aristotle University of Thessaloniki (Main Ceremony Hall of the Aristotle University of Thessaloniki). Its main focus is on methods for observing, estimating and interpreting the Earth gravity field as well as its applications.
GGHS2016 continues the long history of IAG’s Commission 2 Symposia, GGG2000 (Banff, Canada), GG2002 (Thessaloniki, Greece), GGSM2004 (Porto, Portugal), GGEO2008 (Chania, Greece), GGHS2012 (Venice, Italy), with those of IGFS, 1st IGFS Meeting 2006 (Istanbul Turkey), 2nd IGFS Meeting 2010 (Fairbanks, Alaska, USA), 3rd IGFS Meeting 2014 (Shanghai, China) under a unified umbrella, the latter being decided during the XXVI IUGG General Assembly in Prague.
The Joint Symposium aims to provide field of sessions focused on:
- Current and future satellite gravity missions
- Global geopotential models
- Local/regional geoid estimation methods and models
- Absolute and relative gravimetry
- Satellite altimetry
- Height systems and vertical datum unification
- Gravity, mass transport and climate-relevant processes
We are looking forward to welcoming you in Thessaloniki.
