From Storm Station's own record of every report it heard from this station.

Against its reference: each temperature this station reports is compared with the nearest airport or climate reference station that reported within half an hour, up to 15 miles away. The figure is its reading less the reference's, on average, as both were reported; the typical difference is the root mean square. The difference in height is shown where both heights are known.

Its schedule is one report every hour, 24 in 24 hours. Two reports in the same hour count as one received.

How to read a gauge

A gauge measures the height of the water where it stands, its stage, in feet above a fixed mark at that gauge. Two gauges' stages are not comparable: each is measured from its own mark, and a reservoir's is often its height above sea level.

The stage shown is the latest the gauge reported, with the time it reported it. Storm Station hears each gauge on its own schedule and ranks it among its state's stations by its 247 score, how reliably it reports and how its readings hold up: that is its 247 rank.
