The 2026 International Atmospheric River Conference will include plenary talks (10-15 min), lightning presentations (2-3 mins), poster sessions, and breakout room discussions. Plenary sessions will be available virtually, and participants may present remotely if needed.

Key themes:

• Physical, dynamic, and microphysical aspects of ARs
• Aerosol and biogeochemical aspects of ARs
• Observing, identifying, and monitoring of ARs
• Forecasting of ARs from short to seasonal time scales
• Regional aspects and global signatures of ARs
• ARs in past, present, and future climates
• Role of ARs in the changing cryosphere

This year’s special focus will explore the connection between AR science and stakeholders, including:

• Impacts of ARs on the environment and society, including in the context of compound events
• ARs and water extremes: from drought to flood & water management
• ARs and the Ocean: from physical drivers to biodiversity impacts

The full program will be posted here when available.
