IAG Workshop: Satellite Geodesy for Climate Studies

The growing record of space-gravimetric and -geodetic data (GRACE, GNSS, radar altimetry, InSAR, VLBI, …) provides a new view on Essential Climate Variables such as terrestrial water storage and continental ice-mass changes, steric and barystatic sea level variability, sea ice coverage, tropospheric water vapor variations, and others.

These observational data sets have the strong advantage to be homogeneous around the globe, and independent from any other data commonly used to validate climate models.

Geodetic time series start to reveal a complex picture of low-frequency natural climate variability, long-term climate change and other anthropogenic modifications in geodetic data. It is still difficult to evaluate decadal variability from geodetic data alone, but in combination with other observations or reanalyses they provide excellent tools for climate model evaluations.

GGOS Days 2017

​The Global Geodetic Observing System (GGOS) is the observing system of the International Association of Geodesy (IAG).

GGOS works with the IAG components to provide the geodetic infrastructure necessary for monitoring the Earth system and for global change research. It provides observations of the three fundamental geodetic observables and their variations, that is, the Earth’s shape, the Earth’s gravity field and the Earth’s rotational motion.

GGOS Days is an annual comprehensive series of GGOS component meetings, including meetings of the GGOS Consortium, Coordinating Board, Bureaus, Working Groups, and Focus Areas.

COSPAR Symposium 2017

The Committee on Space Research (COSPAR) was established by the International Council for Science in 1958. Among COSPAR’s objectives are the promotion of scientific research in space on an international level, with emphasis on the free exchange of results, information, and opinions, and providing a forum, open to all scientists, for the discussion of problems that may affect space research. These objectives are achieved through the organization of symposia, publication, and other means.

The COSPAR symposium has been initiated by COSPAR which aims to promote space research at a regional level in emerging countries and will be held every two years in a different area of the world. The first COSPAR symposium was in Bangkok, Thailand in 2013 with the theme of “Planetary Systems of our Sun and other Stars, and the Future of Space Astronomy”, and the second symposium in Foz do Iguaçu, Brazil in 2015 with the theme of “Water and Life in Universe”. The third symposium will be held in Jeju, South Korea on 2017 with the topic of “Small Satellites for Space Research”. Worldwide scientists and professionals will get together to discuss of new opportunities of space research with small satellites.

The Symposium will allow various communities to share stimulating discussions and near-future among the scientists using the small satellites, which would be a quantum leap in the field of space science.

Journées 2017, des Systèmes de Référence et de la Rotation Terrestre

The Observatoire de Paris and the Universidad de Alicante are pleased to announce that the “Journées des Systèmes de Référence et de la Rotation Terrestre“ (*) will take place from 25 to 27 September 2017 at the University of Alicante, Spain. The Journées are supported by the International Astronomical Union (IAU) and the International Association of Geodesy (IAG).

In the interest of enhancing the interactions between Astronomy and Geodesy these Journées are devoted to the study of the space-time celestial and terrestrial reference systems and their evolution with time, with the emphasis on the rotation of the Earth. The scope of the meeting will range from concepts and theoretical solutions to observational techniques and data analysis.

The sub-title of this meeting is “Furthering our knowledge of Earth Rotation” and addresses the challenges brought by the accuracy requirements of the Horizon 2020 project. Therefore, our discussions will help to develop the tasks of the IAU/IAG Joint Working Group on “Theory of Earth rotation and validation”, among others.

The topics of interest include, but are not limited to:

- Theory of Earth rotation variations: precession/nutation, polar motion, LOD/UT1

- Observation methods of Earth rotation variations: Earth Orientation Parameters (EOP) determination

- Celestial and terrestrial reference systems and frames: improvements

- Modelling of Earth rotation variations: solar system dynamics and global geophysical fluid mass transports

- Relativity and new concepts in Earth rotation theory

With innovation highlights, technology catalysts, panel discussions on the latest issues and a huge variety of specialist and background information, INTERGEO 2016 is working to plan and steer the future on a sustainable basis. Indeed, it is by pulling together information and communication that we achieve far-sightedness, planning, coordination and concentrated activities.

Some 530 exhibitors from 33 countries, a packed three-day conference programme covering headline issues such as the smart city and BIM and the integrated specialist platforms INTERAERIAL SOLUTIONS and Smart City SOLUTIONS create a sound basis for focussed information-sharing and communication between user sectors.

Taking in four exhibition halls and covering a total area of 30,000 square metres in Hamburg, INTERGEO is once again demonstrating its outstanding international importance and its standing as a leading trade fair for the sector. All the market leaders are there. By exploring trailblazing application areas in greater depth, the trade fair has drawn in new exhibitors, including international brands such as Intel, Oracle and Autodesk. The hosts are expecting to welcome approximately 17,000 visitors from more than 100 countries.
