Session Description

A. GRACE and GRACE-FO Geodesy

A.1 GRACE-FO Project Status

The meeting will open with a GRACE-FO Project Status session consisting of the technical status of the mission and the flight segment, future science operations plans, as well as information on the latest GRACE/GRACE-FO data releases from the Science Data System.

A.2 Analysis Techniques & Inter-comparisons

This session invites presentations about methods, algorithms, and results from GRACE/GRACE-FO data analysis and error assessments providing insights into spatio-temporal signal content including diverse methods of error reduction. We also invite discussions on inter-comparisons between various GRACE/GRACE-FO gravity field time-series and assessments of the significance of the differences and analysis of possible causes.

A.3 GRACE-C, NGGM, and Future Missions

This session is for discussion on the status of the GRACE-FO successor mission GRACE-C, as well as ESA’s NGGM mission and on the progress towards the realization, technology, simulation, and error analyses of future mission concepts. Also invited are papers dealing with methods for bridging data gaps such as, e.g., between GRACE and GRACE-FO.

A.4 The Mean Earth Gravity Field

Results on combination, analysis, and geodetic/geodynamic interpretation of complementary results from GRACE/GRACE-FO, GOCE, altimetry, and terrestrial gravity data for the next generation of mean Earth gravity fields are invited to be presented in this session.

B. Geophysics & Climate Science Applications

B.1 Solid Earth Sciences

This session invites presentations about studies of glacial isostatic adjustment, the Earth's crustal structure, lithospheric and mantle properties, analyses of seismic events, etc., using information from long-term mean and time-variable gravity field models.

B.2 Cryosphere

This session addresses changes of the Earth's ice sheets at all spatio-temporal scales, the science advancements and open questions in the interpretation of these results, current uncertainties as well fusion/cross-validation of GRACE/GRACE-FO data with other sensors and models

B.3 Oceanography

This session invites presentations about advances in oceanographic applications of GRACE/GRACE-FO data products, including signal interpretation and model assimilation. Other topics include, but are not limited to, the validation of data products, the studies of regional or global oceanographic processes and sea level budgets, exploitation of GRACE/GRACE-FO data products jointly with data from other missions (such as GOCE), or other in situ oceanographic measurement systems (e.g. ARGO), etc.

B.4 Hydrology

Presentations reporting on advances in hydrological applications based on GRACE/GRACE-FO data products, including signal interpretation and model assimilation, the assessment of hydrological trends and long-term water storage variations, or GRACE/GRACE-FO data products that are optimized for terrestrial hydrology are invited to be submitted to this session.

B.5 Multidisciplinary Science

This session is open for science topics which do not properly fit into the other available sessions. Also, if you are unsure about the right session for your abstract, please submit it to this session.

B.6 Towards the Operational Use of Satellite Gravimetry

This session focuses on the applications of GRACE/GRACE-FO, together with other remote sensing, in-situ, or numerical model data, to inform resource management, policy development, and decision-making at all time-scales. Some examples include EU's Copernicus Services, NASA's Applied Sciences Program, and other such efforts.
