A lane joins this list when an authoritative source that publishes continuously has been identified — not when it is built, and not when it sounds good. Where we are not capturing, the page says so and asks what you need instead. Nothing on this site is sold for data we are not capturing.
Capturing and sealing today.
Published by sources we already poll, at stations already registered.
Authoritative sources exist and publish continuously. Adapter not built.
Tide, wave, surge and sea state — the closest lane to Louisiana and the one nobody has claimed.
Tornado, hail, lightning and hurricane records — largely event reports rather than instrument readings.
Fire weather, active perimeters, fuel moisture and smoke.
Drought category, soil moisture, evapotranspiration and groundwater level.
Snow depth, water equivalent, ice cover and freeze-thaw.
Regulatory-grade pollutant concentrations and composite index.
Magnitude, epicentre, depth, and shaking actually experienced at a location.
Geomagnetic storms, radio blackouts and GNSS degradation — one federal source, one authoritative scale, no station network.
Sunrise, sunset, twilight, and moon phase — computed from ephemeris, and independently reproducible by anyone.
Sources are sparse, awkward, or of a different provenance shape.
Migration timing, harmful algal blooms, hypoxia, closures — mixed provenance and genuinely awkward.
Vessel position, lock transits and channel closures — pairs naturally with water and marine.
Continuous emissions monitoring, methane detection, discharge reports and release events.
An authoritative, continuously publishing source has been identified.
That source's API, cadence and published uncertainty are confirmed.
The adapter is scoped against sources we already poll.
Records are sealing. Only now can anything be sold.
A lane is only admitted at all when the source publishes its own uncertainty alongside the value. Otherwise we would be inventing a confidence figure, and an invented confidence figure is worse than no lane.
