Eleven live.
One scale.

Every peril below is a calibrated 90 m global surface, modeled with the method that fits its physics. Every peril ships in Petrel Surfaces — a 0–1 calibrated score, a 5-class risk band, a per-pixel uncertainty layer, and an input-coverage mask. Per-return-period intensity rasters (Petrel Returns) are live for hurricane, windstorm, extreme heat, extreme cold, and drought; stochastic event sets for the remaining extreme-value perils are on the roadmap.

How to get it: a free ~5°×5° sample per peril is on the public CDN today (no signup). The hosted point-query API is live and self-serve, metered through Stripe — get a free API key. Full bulk vintage downloads are sold under enterprise contracts — contact sales. Per-hazard model cards land with the public docs portal in 2026.Q3.
