Built for scale,
engineered for decisions.
Petrel is the infrastructure layer beneath site selection, climate disclosure, and underwriting triage — three workflows where a comparable 0–1 score across hazards beats a single return-period curve. Six commitments make that possible.
90 m, every place on Earth
Every hazard, one grid. Native 90 m output in EPSG:4326, aligned across all 24 perils so portfolios score on the same coordinate frame. No mosaic seams, no national-boundary discontinuities, no ocean/land step changes outside the explicit coastline mask.
Auditable by the pixel
Every release ships a per-pixel uncertainty layer, a per-pixel input-coverage mask, a STAC item, and a versioned methodology document. Every input dataset is cited by source, version, and download date. When the methodology changes, the version number changes.
One scale, every peril
The same 0–1 calibration philosophy runs across all 24 perils — supervised ML where event inventories support it, Gumbel/GEV statistics for return-period perils, RUSLE for soil, site-amplified PGA for earthquake. The reason a portfolio cross-peril comparison actually means something.
Three ways in
Free public sample COGs for every live peril at data.petreldata.io — pull with curl, open in QGIS / rasterio. Hosted point-query API in private beta (Stripe-metered) for single addresses and portfolios. Full bulk vintage downloads — every peril, every release, as Cloud-Optimized GeoTIFFs — sold under enterprise contracts via sales.
Annual vintage, versioned releases
Each Petrel Surfaces vintage is a frozen, citable snapshot. New vintages annually, point releases when methodology improves or input data refreshes. Old vintages remain accessible — once you score a portfolio against vintage 2026, that scoring is reproducible forever.
No black boxes
Every model, every input, every training inventory, every validation cohort is documented publicly. The methodology PDF for each peril describes the algorithm, the data sources, the calibration philosophy, and the known limitations. The science is the product.
