2026 S2S Land-atmosphere Interactions Workshop

The 2026 S2S Land-atmosphere Interactions Workshop, Advancing Understanding of Land-Atmosphere Interactions and Processes on S2S Predictability, is a follow-on to the 2025 summer workshop.

The 2026 Workshop will focus on the role of land–atmosphere interactions in predictability at subseasonal-to-seasonal (S2S) timescales (here defined as two weeks to three months). Building on last year’s outcomes, the workshop will bring together researchers, modelers and practitioners working on:

• Process-oriented metrics for evaluating land–atmosphere interactions in S2S models
• Application-oriented metrics to assess user-relevant aspects of S2S prediction
• Experimental protocols for coordinated S2S land–atmosphere experiments
• Demonstrations and early results applying these metrics and protocols in S2S modeling systems
• Community regionally refined simulations
• Applications of S2S forecasts to agriculture, water resources, wildfire, heatwave, extreme rainfall, and more

The program will include a mix of science and applications talks, working-group showcases, discussion of coordinated experiments, and planning for future community efforts.
