G3P at the EGU General Assembly 2022 in Vienna

On 23-27 May 2022, the European Geosciences Union is organizing its annual general assembly in Vienna, Austria. With a total of six presentations, G3P is well represented at EGU2022. What will be presented and by which consortium members? And where will it take place? These questions, and more, will be answered in the overview below.

Tuesday 24 May

17:00 - 17:07 | Room 2.31

The first G3P-related presentation will be given as part of session HS8.18 on Tuesday 24 May. During this session on water scarcity and management in dry regions, G3P project members Ehsan Sharifi and Andreas Güntner (GFZ) give a virtual presentation on downscaling WGHM-based groundwater storage data using regression method. Together with the Islamic Azad University in Tehran, they will present a regional study over Qazvin Plain in Iran.

Wednesday 25 may

16:08 – 16:13 | Room 2.17

On Wednesday 25, there are two G3P presentations, one the snow component and one more general on the first project results. The first will be given at 16:08 as part of session HS2.5.2 on recent advancement in estimating global, continental and regional scale water balance components. Miriam Kosmale (Finnish Meteorological Institute) will give an in-person presentation on the global snow water equivalent (SWE) for continuous groundwater monitoring from space, with special focus on the uncertainties, evaluation, and application of it. Within the G3P project the FMI is producing a global gap-filled SWE product that describes the snow compartment for global groundwater estimation. The product complements remote sensing-based information with model-based data for regions where remote sensing can’t observe SWE on global scale. Microwave and optical remote sensing sensor techniques are the basis for FMI’s Near-Real-Time SWE monitoring services from satellite. Validation with in-situ reference is presented. Pixel-level uncertainties provided with the snow product support efforts on groundwater estimation. Model- and remote sensing-based SWE are evaluated on various regional scales.  As part of the new Gravity-Based Groundwater Product G3P, global Snow Water Equivalent products will be presented and discussed.

17:42 – 17:48 | Room 2.17

Consequently, in the same room, Ehsan Sharifi (GFZ) will present the preliminary results of the Global Gravity-based Groundwater Product (G3P) data set and its uncertainties, as well as its evaluation by independent groundwater data. This in-person presentation will be part of session HS2.5.3 about understanding groundwater processes across large domains.

Thursday 26 May

08:30 - 08:36 | Room 2.16

On Thursday morning, Frank Flechtner of the Helmhotz Centre Potsdam / GFZ will give a virtual presentation as part of session G4.2; Satellite Gravimetry: Data Analysis, Results and Future Mission Concepts. During this presentation 'GRACE-FO science results and mission status', Flechtner will give an update the current GRACE-FO mission status and near-term plans, including instrument and flight system performance (i.e., satellite health status and outlook, performance of precise inter-satellite ranging from the K/Ka band and Laser Ranging Interferometers, and accelerometry as processed at Jet Propulsion Laboratory (JPL), the official Level-1 data analysis center). Also, he will discuss the GRACE-FO science data quality, reprocessing plans, and highlight recent science results, discoveries, and applications. Finally, he will conclude with a short outlook towards achieving continuity with future mass change missions.

13:25 | Room 1.31/32

In the afternoon, IGRAC/TU Delft Researcher Alexandra Urgilez Vinueza will present during session NH3.8 about landslide monitoring and its recent technologies and new perspectives in room 1.31/32. In her in-person presentation entitled ‘A new method to detect changes in displacement rates of slow-moving landslides using InSAR time series’, she will present a method to identify accelerations and/or decelerations of slow-moving landslides in a regional scale using satellite-derived displacement time series.

Friday 27 May

10:45 - 10:52 | Room N2

On the last day of the assembly, Ines Dussaillant (WGMS, University of Zurich) will conclude G3P’s contribution with an in-person presentation about an annual mass balance estimate for each of the world’s glaciers based on observations. This presentation, based on work with other G3P consortium member LEGOS, will be given as part of session CR1.3 about observing and modelling glaciers at regional to global scales.
