Wind, precipitation, temperature and visibility — published by sources we already poll at stations already registered.
Published by sources we already poll, at stations already registered.
Sustained speed, gust peak, direction, and duration above a threshold.
Accumulation, intensity, rate, snow water equivalent, duration.
Air temperature, dewpoint, heat index, wind chill, freeze duration, degree days.
Prevailing visibility, fog and obscuration, cloud ceiling, barometric pressure.
An instrument read a value at a place and a time.
Measured at a fixed station. The record discloses which one and how far it is from you.
Published by an authoritative operator of the instrument.
Wind is water's datum problem in a different hat: speed at what height, averaged over what interval. A ten-metre two-minute sustained wind and a three-second gust at a different mast height are not the same number and must never be compared as though they were.
Not named here yet. Candidate sources for this lane exist and are identified internally, but they have not been verified against the primary documentation — and an unverified source attribution on a public page is the exact mistake this company exists to avoid. They appear here when they have been checked, not before.
A policy triggers at a wind speed. A parametric crop cover pays on rainfall below a threshold. A cold-chain shipment spoils. A collision turns on what could be seen.
That framing is our analysis of where disputes arise, not a claim of fact about any matter.
We are not capturing this lane today, so there is nothing here to sell you and we are not going to pretend otherwise. What we do want is to know what you would actually ask it. Requests decide what gets built next — that is not a courtesy, it is how the order is set.
