Sentinel-1 SAR
Synthetic-aperture radar imagery cycles every six hours. Mill-level thermal posture extracted on every revisit, independent of cloud cover or daylight.
Arc · Planetary signal index
Ground truth for the industrial economy.
Arc indexes mills, vessels, distributors, and exchanges into a single observation layer. Every signal is timestamped, tiered, and routed through the Arc Signal Transformer before anything downstream — including MESO-1 — touches it.

Observation layers · Live coverage
Four layers of industrial state — observed continuously.
Each layer carries an independent observability budget. Together, they form the calibration substrate every Palisade model is trained against.

Signal sources
Primary feeds. Each ground-truthed at the source.
Every feed is timestamped, tiered, and passed through the Arc Signal Transformer before any model touches it. Provenance is preserved end-to-end.

AIS vessel telemetry
Live vessel positions filtered for steel-carrying load profiles. Lane density, transit time, and dwell scored per port call.

Exchange settlements
HRC, CRC, rebar, and regional indices stream into the calibration layer. Every model trained at Palisade is anchored to settled prices.
1,608 distributors · 46 regions

Distributor graph
Inventory listings, quote responsiveness, and regional concentration mapped continuously across 1,600+ distributors.
Market scale
Steel moves at planetary scale.
Arc covers it.
Coverage before inference. Ground truth before forecast. The observability budget runs first — every model trained at Palisade reads from this substrate.

Industrial-grade observation, ground-truthed against settlement.
Arc is published. Every release ships a versioned technical brief — coverage methodology, source provenance, calibration intervals, and known blind spots. Operators and counterparties read the same primary source the team does.

Outcomes
What better observation produces.
The economic value of Arc is not the data — it's what ends up in the operator's day, and how much earlier it gets there.
9 days
Earlier procurement entry vs. market average
Arc surfaces price-inflection signals before broad market confirmation.

Annual efficiency loss in undigitized distributors
The baseline erosion Arc is designed to reverse — before models even fire.
