SUMMARY:GRACE Hackweek 5
DESCRIPTION:An online school on time-variable gravity from GRACE and GRACE-FO satellite missions\nSatellite gravimetry has become an indispensible tool for studying the earth system. The satellite missions CHAMP\, GRACE/GRACE-FO and GOCE along with Satellite Laser Ranging have demonstrated the utility of time-variable gravity data in understanding the mass changes and their transport within and between the hydropshere\, cryosphere\, atmosphere\, oceans and the solid earth. \nThe challenging aspects of satellite gravimetry are the recovery of time-variable gravity from observations due to the low signal- to-noise ratio\, and the use of time-variable gravity data by non- geodesists. It is our aim in this online school to give an idea of the time variable gravity field recovery process from satellite gravimetry missions\, and also to help non-geodesists to get to grips with handling time-variable gravity data from GRACE/GRACE-FO. \nThe online school is open to everyone interested in using time- variable gravity for their research. Certificates will be issued to participants who complete all the labs. We look forward to your participation and a fruitful online school. The last date of application is September 19\, 2025 (UTC). \nRegistration: https://forms.office.com/r/WzP7GdBbwk \nMore Info: GRACE Hackweek 5 – Program \n  \nOrganizing Committee: \nProf. Balaji Devaraju (IIT Kanpur\, India); Prof. Nico Sneeuw (Uni. Stuttgart\, Germany); Prof. Matthias Weigelt (Leibniz Uni. Hannover\, Germany)

SUMMARY:15th International School on “The Determination and Use of the Geoid”
DESCRIPTION:Dear Colleagues\, \nWe are glad to inform you that the International Service for the Geoid (ISG) has organized a new edition of the traditional International School on “The Determination and Use of the Geoid”. It has been planned in cooperation with the Institute of Ionosphere (Almaty\, Kazakhstan)\, which fostered this initiative. \nPlease share this announcement with potentially interested students\, because the registration is still open. A maximum number of 40 attendees can be accepted. \n15th International School on “The Determination and Use of the Geoid”  \nApril 7-11\, 2025 \nFrom April 7th to 11th\, 2025\, the 15th International School on “The Determination and Use of the Geoid” will be held at the Institute of Ionosphere in Almaty\, Kazakhstan. This event will be conducted in person\, and all classes will be delivered in English. \nThe intensive week-long Geoid School is aimed at training students\, early-career scientists\, and professionals from national agencies\, universities\, and research institutes by providing them with the knowledge and skills necessary for computing and applying gravimetric geoids in various scientific and technical geodetic applications. Participants will gain valuable insights into the latest advancements in geoid determination and have the opportunity to establish international collaboration and interaction with experts in gravity field modeling. \nMoreover\, the School emphasizes the importance of interaction between the scientific community and cartographic agencies responsible for the development and modernization of national geodetic infrastructure. This collaboration ensures the effective translation of scientific research into practical applications for the improvement of regional and local geodetic networks. \nThe Geoid School is organized in partnership between the Institute of Ionosphere (Almaty\, Kazakhstan) and the International Service for the Geoid under the International Association of Geodesy. \nFor more information\, please see the following website: https://geoid-school.ionos.kz/ \n  \nKind regards\, Daniela Carrion\, Mirko Reguzzoni\, Daniya Shoganbekova and Asset Urazaliyev
