Snow depth, water equivalent, ice cover and freeze-thaw.
Authoritative sources exist and publish continuously. Adapter not built.
Depth at the measuring site at the observation time.
Water content of the snowpack at the site.
Charted ice extent and thickness class.
Observed ice state at the reach.
Count of transitions across freezing at the station.
An instrument read a value at a place and a time.
An analyst or a model produced this from other data. It is a product, not a sensor.
Measured at a fixed station. The record discloses which one and how far it is from you.
Covers an area, not a point. There is no nearest station, and we will not invent one.
Published by an authoritative operator of the instrument.
An authoritative body's analytical product. Its uncertainty is the source's own.
Depth at a site and modelled depth over a basin are different claims. So is snow on the ground versus snow that fell, and a roof-load dispute turns on exactly that distinction.
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.
Roof collapse under snow load. A slip-and-fall where ground conditions are contested. Navigation closure on the upper river. Spring runoff feeding a flood claim.
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.
