Over the course of its sessions\, it has established itself as a research forum in the fields of Geodesy\, Seismology\, Meteorology\, Geomagnetism\, Hydrology\, Oceanography\, Volcanology\, Applied Geophysics\, and Cryospheric Sciences\, as well as a place for meeting and scientific exchange between Spanish and Portuguese researchers through the presentation and discussion of papers in these fields. The COVID-19 period marked the largest gap in the established periodicity\, which we now wish to resume. Thus\, two years after the last meeting\, which took place in Évora in 2024\, the 2026 meeting will be held in Spain. Next June\, from the 16th to the 19th\, Universidad Politécnica de Madrid and its Higher Technical School of Topography\, Geodesy\, and Cartography will host the 12th Spanish-Portuguese Assembly of Geodesy and Geophysics.

The school will be for four days and focusing on training Early Careers to improve their skill of satellite data processing and hydrological data assimilation. The program will be ~50%-50% on theory and practical sessions. The focus will be on advanced techniques and open challenges in measuring and modeling the water cycle\, as well as integrating satellite-based observations\, including Satellite Gravity (GRACE/GRACE-FO and future missions NGGM/MAGIC)\, Satellite Altimetry (Sentinel and SWOT)\, and Soil Remote Sensing into large-scale hydrological models. Participants will be introduced to ensemble-based sequential Data Assimilation techniques for merging satellite data with models. The school emphasises hands-on learning\, featuring practical exercises in Python\, along with various interactive activities. \nThe school is free of charge\, but a registration process will be followed to select the most relevant audiences.
