Cascadia Sentinel · Node One Live

The Earth, sensed as one connected system.

A distributed, GNSS-synchronised monitoring network that brings many Earth domains onto a single sub-microsecond timebase, turning fragmented observations into one coherent, machine-ready data stream.

01 · The Approach

One network. One clock. One data object.

Earth's systems are physically coupled, but the data about them usually isn't: different domains arrive on different clocks, in different formats, from different networks, and the connections between them are lost. Cascadia Sentinel disciplines every sensor at every node to one shared, sub-microsecond timebase and writes the result into a single, time-aligned archive. The unification is the clock and the shared representation, not any single model.

02 · Why Timing Matters

Sub-microsecond alignment, by design.

Most multi-sensor sites stitch domains together after the fact, interpolating across mismatched clocks. Cascadia Sentinel captures every domain on one GNSS-disciplined timebase, so cross-domain signals are recorded at the timescale they actually happen, with traceable timing on every record. That coherence is what makes the data trustworthy for modern AI models.

03 · Proof of Concept

Node One is live on the outer BC coast.

Rugged Point Coastal Science Observatory, on a deliberately data-sparse stretch of the exposed Pacific margin, hosts the first node: five operational domains, on one clock, streaming today. It is both our proof of concept and the template for every node that follows.

04 · What's Live

Five domains, operational today.

Live

Seismic

Broadband ground motion. Regional seismicity and tectonic noise.

Live

Weather

Surface meteorology: wind, pressure, humidity, temperature, radiation.

Live

Geomagnetic

Magnetic field fluctuations and geomagnetic activity.

Commissioning

Oceanic

Sea-surface temperature and wave radar: height, direction, period.

Live

Solar

Solar and geomagnetic forcing, derived from ground magnetometer variation.

The operational core of a platform designed to grow toward its full multi-domain suite.

05 · The Network

One node. Built to replicate.

Node One is the template, not the destination. Every node runs the same synchronised, multi-domain stack and writes to one schema and one timebase, so data is directly comparable from site to site and the network grows by repeating a proven design. Further nodes are in development, extending coverage across the Pacific margin and both hemispheres.

01

A portable stack

The same synchronised, multi-domain instrument stack at every node.

02

Comparable everywhere

One schema, one timebase, so sites can be read against each other directly.

03

A growing network

Further nodes in development across the Pacific margin and both hemispheres.

06 · The Data

A machine-ready archive, built for models.

07 · Who It's For

Ground truth for a new generation of Earth-system AI.

AI weather & climate models

Time-aligned training and validation data, where models are weakest: against real ground observations.

Energy & grid operators

Space-weather and geomagnetic signals for grid-stability early warning.

Climate risk & insurance

Coupled, multi-hazard data for compound-risk modelling.

Earth observation & research

A multi-domain ground-truth layer that validates and enriches satellite products and feeds coupled-system research.
