AGU26 Fall Meeting 2026

About AGU26

AGU26 is the American Geophysical Union’s annual meeting for research across the Earth and space sciences. The 2026 edition runs for five days at Moscone Center in San Francisco under the meeting theme “Where Science Connects”. Its scale supports specialist scientific exchange while also creating links between disciplines that study connected planetary systems, from Earth’s interior and oceans to the atmosphere, Sun and wider Solar System.

The programme combines scientific sessions with posters, workshops, panel discussions, hands-on learning and career activity. Researchers can present findings within established subject communities, but the meeting is also structured for work that crosses boundaries such as climate impacts, coupled geophysical processes, remote observation and data-intensive science. That breadth distinguishes AGU26 from a narrowly defined space conference: planetary and heliophysics research sits within a much larger geoscience setting. The official schedule and session search should guide detailed planning because concurrent content is distributed across many scientific sections and formats. Attendees interested chiefly in space should therefore identify relevant planetary science, space physics, aeronomy and Earth-observation sessions before building an itinerary.

Event history and organiser

The American Geophysical Union was established in 1919 and has developed its annual meeting into a central gathering for the international Earth and space science community. The event was long widely known as the AGU Fall Meeting, a name that remains common in searches and professional conversation, while AGU now presents it as the Annual Meeting. Its continuing identity comes from peer research, disciplinary sections and direct exchange between scientists rather than from a commercial exhibition alone. AGU organises the meeting, manages abstract and session processes, publishes programme information and provides registration and housing routes. The 2026 edition returns to San Francisco and Moscone Center, a location closely associated with the meeting’s recent history. “Where Science Connects” positions the current edition around collaboration across fields and career stages. Historical attendance or programme figures can vary by edition, so this guide relies on the current AGU26 pages for present logistics and format.

Topics and themes

AGU26 covers the connected systems of Earth, its space environment and neighbouring worlds. The meeting’s disciplinary breadth is most useful when each subject is linked to the scientific communities presenting it.

• Solid Earth and geophysics: seismology, tectonics, volcanology and geodesy examine Earth’s structure, dynamics and physical change.
• Atmosphere and climate: observations and models connect weather, atmospheric chemistry, climate processes and impacts across different timescales.
• Oceans, water and cryosphere: ocean science, hydrology, glaciers and polar systems show how water moves through a changing planet.
• Planetary and space science: planetary surfaces, heliophysics, aeronomy and space weather connect Earth-focused research with the Solar System.
• Data, hazards and societal applications: remote sensing, computational methods and risk research turn scientific measurements into practical insight for communities and decision-makers.

Who should attend?

AGU26 is primarily for Earth, atmospheric, ocean, climate, planetary and space scientists who want to present or follow current research. University faculty, laboratory teams and agency researchers can use the meeting to compare results across specialised sessions and find collaborators in adjacent fields. Doctoral candidates, students and early-career scientists have access to poster and presentation experience, mentoring and career activity within a large professional community. Educators, science communicators, policymakers, data specialists and organisations that apply geoscience may also find relevant programmes, particularly around hazards, climate and societal impacts. Space-sector attendees should expect a science-led meeting rather than a conventional aerospace trade show and should search the programme for planetary, heliophysics, space-weather and Earth-observation content that matches their work.

Practical information

AGU26 runs from 7 to 11 December at Moscone Center, 747 Howard Street, San Francisco. Registration and housing are managed through AGU, and attendees should use the official hotel block and travel guidance where appropriate.
