SUMMARY:PhHS-IHRF2026 - Int. Symposium on Physical Height Systems and the IHRF
DESCRIPTION:⚠️⚠️Given the recent evolving circumstances in the Middle East\, we would like to let you know that the IAG SC2.2\, SC2.4\, IGFS and GGOS Symposium “Physical Height Systems and the International Height Reference Frame – PhHS–IHRF2026” will be postponed to a future date. As the situation is quite uncertain\, no plans have been made yet\, hence we will keep you updated. Apologies for the last-minute change and any inconvenience this may cause to your schedule. ⚠️⚠️ \nThe PhHS-IHRF2026 “International Symposium on Physical Height Systems and the International Height Reference Frame” will be held in Riyadh\, Kingdom of Saudi Arabia from 7 to 9 April 2026. It focuses on methods for observing\, estimating and interpreting the Earth’s gravity field and the geoid with special emphasis on height systems\, physical height determination and the realization of the International Height Reference System (IHRS) into the International Height Reference Frame (IHRF). PhHS-IHRF2026 is a Joint IAG Symposium co-organized by IAG SC2.2 “Geoid\, Physical Height Systems and vertical datum unification”\, SC2.4 “Gravity and Geoid”\, the International Gravity Field Service (IGFS) and the Global Geodetic Observing System (GGOS). \nOfficial Symposium Website: https://geosa.gov.sa/en/Pages/phhs-ihrf-2026.aspx \n \nScientific Organizing Committee: \nGeorge Vergos (SC2.2 Chair\, IHRF CC director\, IGFS CB Director)\nRossen Grebenitcharsky (SC2.2 Vice-Chair)\nRiccardo Barzaghi (IGFS President)\nLaura Sanchez (GGOS President)\nHussein Abd-Elmotaal (SC2.4 Chair)\nRene Fordberg\nZuheir Altamimi  \nLocal Organizing Committee: \nAlShahrani Sultan Falah\nMohammed AlArjani\nMashael AlHarbi\nSaad AlQahtani\nAbdulmohsen AlDosari\nSaleh AlFaris\nEslam Abdulsamie

SUMMARY:Summer School on "Satellite-based Hydrological Data Assimilation"
DESCRIPTION:We are thrilled to announce the upcoming Summer School on “Satellite-based Hydrological Data Assimilation”\, specifically designed for early career scientists (MSc\, PhD\, and Postdoctoral researchers). This exciting event will be hosted by the Geodesy Group at Aalborg University\, Denmark\, from August 26th to 28th\, 2025. \nWhy Attend? Dive into advanced techniques and tackle open challenges in measuring\, modeling\, and predicting water cycle variability. Learn how to leverage Satellite Gravity (GRACE/GRACE-FO)\, Satellite Altimetry (Sentinel and SWOT)\, and Soil Remote Sensing (e.g.\, SMOS and SMAP) to enhance large-scale hydrological models through Data Assimilation. Participants will gain hands-on experience with ensemble-based sequential Data Assimilation techniques\, and merging satellite data with models. \nWhat to Expect? \n\nInteractive Learning: Engage in practical exercises using Matlab/Octave and Python.\nHands-on Activities: Explore the data assimilation package (PyGLDA) and the GRACE-FO post-processing package SaGEA through practical exercises.\nExpert Lectures: Learn from world-leading scientists\, including Dr. Henrik Madsen (DHI)\, Professor Peter Bauer-Gottwein (University of Copenhagen)\, Professor Petra Döll (University of Frankfurt)\, Professor Jürgen Kusche (University of Bonn)\, Professor Gabriëlle De Lannoy (KU Leuven)\, Dr. Anke Fluhrer (German Aerospace Center\, DLR)\, Dr. Guillaume Rmillien (French National Centre for Scientific Research\, CNRS)\, Professor Mohammad Shamsudduha (University College London)\, and Professor Maike Schumacher (Aalborg University).\n\nRegistration Details: \n\nCost: Free registration!\nDeadline: End of April 2025\nLocation: Geodesy Group\, Aalborg University\, Aalborg\, Denmark\nTime: August 26-28\, 2025\n\nFor more information\, the program\, and the registration form\, please visit: Summer School Information https://www.plan.aau.dk/summer-school-satellite-based-hydrological-data-assimilation-e134157 \nEvent Category: igfs
