How to read this page

measurement

An instrument read a value at a place and a time.

station

Measured at a fixed station. The record discloses which one and how far it is from you.

instrument

Published by an authoritative operator of the instrument.

What we cannot compare

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.

Sources

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.

Where the answer is worth money

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.

What would you need from atmospheric?

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.
