New film by GGOS - Global Geodetic Observing System on "Terrestrial Reference Frames - Connecting the World through Geodesy" with contributions by DGFI-TUM highlights the fundamental importance of highly precise #ReferenceFrames for a wide range of scientific and societal applications: bit.ly/trf-film

Coastal Assessment of Sentinel-6 Altimetry Data during the Tandem Phase with Jason-3: Study within #ESA's S6-JTEX project highlights the improved monitoring capabilities of #Sentinel6's SAR #altimetry product compared to its predecessor mission #Jason3: doi.org/10.3390/rs1517…

Nice bit of work on Polar Ocean Tides that I was fortunate to contribute to, led by DTU Space's Ole Andersen and Stine Rose. Tides in the Polar regions are very exciting and we are starting to understand them more and more thanks largely to Cryosat-2. See mdpi.com/2072-4292/15/1…

For 30+ years, satellite #altimetry has observed oceans & water bodies. DGFI-TUM's Open Altimeter Database (openadb.dgfi.tum.de) offers free multi-mission #OceanData & high-level products like SSH and ocean tides. Explore OpenADB in our latest paper: doi.org/10.1002/gdj3.2…

Arctic Tidal Constituent Atlas (ArcTiCA) now introcuced in Nature Scientific Data: nature.com/articles/s4159…. The joint initiative led by DGFI-TUM aimed at providing a harmonized in-situ database for tidal research in the Arctic. ArcTiCA is available at doi.org/10.18739/A2VT1….

Uncertainties in relative Sea Level projections are underestimated. This is due to the effects of regional-scale and non-linear vertical land motion (VLM) as shown by a probabilistic reconstruction of VLM over 1995-2020: nature.com/articles/s4156… #NatureGeoscience Nature Portfolio

High-res #WaterSurfaceSlope derived from Satellite #Altimetry for rivers in Poland shows an average RMSE of 27 mm/km (11 mm/km in lowlands) compared to slopes from gauge data. The method can be applied worldwide and benefit flow velocity & discharge: WRR, doi.org/10.1029/2023WR…

Thrilled to announce the GGOS - Global Geodetic Observing System Topical Meeting on the #Atmosphere! Join us on Oct 7-9 to explore cutting-edge research in atmospheric and magnetospheric studies. Supported by IUGG, IAGA, IAG, GFZ, DGFI-TUM, #BEV. More info: shorturl.at/kpJLO

Gridded #sealevel maps are the favorable #altimetry data format for #ocean & climate studies but lack effective resolution at higher temporal scales. We evaluated them w.r.t. a model and highlight the relation to #wind on the SW Atlantic Continental Shelf: link.springer.com/article/10.100…

Annual Report 2023 of DGFI-TUM is now available. It highlights our last year's research activities on #SpaceGeodesy, #ReferenceFrames, Satellite #Altimetry and Atmosphere/#SpaceWeather: mediatum.ub.tum.de/doc/1751072/17…

New method estimates #ECV #RiverDischarge only from remote sensing - perfect for filling gaps in the global in-situ network. By combining 20 years of satellite #altimetry with high-res imagery, we model ungauged rivers down to <100 m width. Only 12% RMSE! doi.org/10.1016/j.rse.…

🌍 GGOS - Global Geodetic Observing System Topical Meeting on the #Atmosphere 2024 wrapped up! Three days of great discussions on geodetic & geophysical tech for atmosphere & magnetosphere research. Thanks to all who participated & shared insights! IUGG IAG International Association of Geodesy IAGA GFZ DGFI-TUM

New research on tides in complex coastal regions from the #SWOTsatellite! Results indicate impressive accuracy, particularly in areas where global tide models struggle, highlighting the potential of SWOT for future research & ocean modeling! doi.org/10.1029/2024GL… Michael Hart-Davis

Caspian Sea on UN climate summit doorstep ebbs towards record low: Financial Times (@ft) reports on the drastic decline in the Caspian Sea level, citing data from DGFI-TUM's DAHITI database (dahiti.dgfi.tum.de): on.ft.com/4inbFVZ

Arctic Data Center (Arctic Data Center) blog post highlights collaborative effort to develop the Arctic Tidal Constituent Atlas (ArcTiCA) by Michael Hart-Davis of DGFI-TUM and colleagues:
