Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-10-09

Use AIFS ENS v2 as complementary probabilistic guidance with application-specific monitoring.

Why
Operational feeds and independent recent comparisons demonstrate useful forecast skill, while regional extremes and probability calibration need broader evaluation.
Next
Validate v2 against local observations and IFS ENS across seasons, checking reliability and extreme-event performance before automating consequential decisions.

Constraints

Blockers

  • Independent current-version evidence covers a limited observation window.
  • Analysis-based comparisons do not establish local observational accuracy.
  • Probability reliability and extreme-event calibration need dedicated checks.
  • Regional skill can change after model and initialization upgrades.
