Colour scales
DRAWN FROM THE SERVER'S OWN TABLESEvery scale below is fetched from the same endpoint the viewer uses, so this page cannot drift from what the map actually draws — the bars are the server's own colour tables, at the server's own break points.
Scales are written in display units — dBZ, mm/h, thousands of feet — rather than in an abstract 0-to-1, because that is how a scale is read and where its break points mean something. Reflectivity offers four; the other products are read for magnitude rather than pattern-matched against a lifetime of television, so one good scale each is enough.
Why the light end of every scale is see-through. Fifteen dBZ of stratiform can cover four states, and drawn opaque it hides the map underneath it — which is the map you zoomed in to read. So every scale carries an opacity curve as well as a colour curve: drizzle stays translucent and a core goes solid.
