1. NGGM mission: Overview and Status Update

This theme will provide an overview of the NGGM mission, including updates on its development status and scientific readiness, as well as the status of ESA–NASA collaboration on MAGIC.

2. NGGM and MAGIC data products, processing, calibration and validation strategies

This theme covers strategies for generating NGGM and MAGIC products, including the processing and associated uncertainties of Level-1, Level-2 and Level-3 products. It will examine the latest algorithmic advances, anticipated product performance, and approaches to verifying and validating mission performance. It will also address calibration and validation strategies and potential support campaigns.   

3. NGGM and MAGIC science and applications: Focus Hydrology

This theme focuses on hydrology science and applications enabled by NGGM and MAGIC. Topics include, among others, monitoring hydrological Essential Climate Variables (ECVs), closing the water budget, assessing global and regional climate change and human impacts on the water cycle, and using mass-change products operationally to track drought and flood potential and support water management. Contributions addressing the operational potential of NGGM and MAGIC are particularly welcome.

4. NGGM and MAGIC science and applications: Focus Cryosphere

This theme focuses on cryosphere science and applications enabled by NGGM and MAGIC. Topics include improving ice-mass balance estimates for Greenland, Antarctica and mountain glaciers; understanding glacier dynamics and responses to climate change; and assessing short-term extreme weather and seasonal mass-balance variations to improve projections of glacier health, freshwater availability and sea-level rise. Contributions addressing the operational potential of NGGM and MAGIC are particularly welcome.

5. NGGM and MAGIC science and applications: Focus Oceanography, Climate and Atmosphere

This theme is dedicated to oceanography, climate and atmosphere related science and applications enabled by NGGM and MAGIC. The topics span from monitoring of the Atlantic Meridional Overturning Circulation (AMOC) to improving tidal and ocean circulation models, the estimation of global ocean heat uptake, ocean heat content changes, Earth energy imbalance, closure of the sea level budget at global and regional scales and knowledge of neutral density and winds in the thermosphere. Contributions addressing the operational potential of NGGM and MAGIC are particularly welcome.

6. NGGM and MAGIC science and applications: Focus Solid Earth and Geodesy

This theme is dedicated to Solid Earth and geodesy related science and applications enabled by NGGM and MAGIC. Topics include, among others, the knowledge improvement of crust and mantle structure through quantification of gravity changes during all phases of the seismic cycle and the role of NGGM and MAGIC products to support geohazard monitoring. The theme will also address improvements in the separation between the Glacial Isostatic Adjustment (GIA) due to ice load history and present-day ice mass variations, constraints on mantle viscosity inversion, quantification of drainage basin sediment discharge to the oceans, monitor of undersea seamounts growth and impact of terrestrial water storage anomalies on crustal deformation and seismicity. Related to geodesy, the theme will address improvements in the unification and closure between regional and national height systems, the static and time-varying realisation of the International Height Reference Frame (IHRF) and the accuracy of satellite orbits using temporal gravity as background model.  Contributions addressing the operational potential of NGGM and MAGIC are particularly welcome.

7. Beyond NGGM and MAGIC

This theme focuses on science enabled by observations that complement and follow NGGM and MAGIC. These include ground- and airborne-based datasets that enhance NGGM and MAGIC products in addressing user needs, including superconducting gravimetry and airborne gravity gradiometry campaigns. The theme will also address the evolution of satellite gravimetry post-NGGM and post-MAGIC in the mid-to-long term timeframe (e.g. 2040+) addressing topics such as emerging user requirements, mission concepts, new technologies and expected science and applications of future satellite gravity missions.

ESA will publish the "Summary and Recommendations from the NGGM Science and Applications Workshop 2027” report, with contributions from the workshop scientific committee.

The Abstract submission interface is now open, and we invite you to submit your abstract HERE along with your selection of the workshop themes and the type of presentation (oral or poster) proposed.

Abstract length should be at least 200 words and a maximum of 500 words (one A4 page, single space normally contains 400-500 words).

Information about the co-authors (name, last name, affiliation, contact E-mail) is required.

PPT template for presentations will be available on this webpage closer to the event date.

The Workshop will take place on 24-26 May 2027 at the Le Dôme convention centre, Carcassonne, France.

Carcassonne, located in the south of France, can be reached by several means of transport.

• By plane: Travellers can fly to Toulouse and continue their journey by train or bus.

• By train: Carcassonne can be reached from Italy via the French railway network, usually with one or more transfers.

• By car: Travellers can drive through France using the motorway network, which also allows them to visit other destinations along the way.

• By bus: Long-distance bus services offer a generally more economical alternative, although the journey may take longer.

Once in Carcassonne, visitors can easily reach the famous medieval fortified city on foot or by local transport. The most suitable means of transport depends on the traveller’s budget, available time and departure location.

The working language of the workshop is English.

 No participation fees will be charged.

 Participants are expected to finance their own travel and accommodation expenses.

To facilitate accommodation arrangements for event participants, preferential rates have been negotiated with two hotels located in the vicinity of the venue.

Please find below the details of the selected hotels, together with the relevant booking procedures.

Please note that other accommodation options are available in the area, and participants are free to choose alternative hotels according to their preferences and needs.
