Station charts
Rank 4 of 1,869 in Arizona, Oct 16. The 247 rank orders a state's stations by their 247 score out of 100: how reliably they report, how accurate their readings are against a reference station, how their readings pass their checks, and how they stand against the forecast.
247 score99.2of 100
Equal scores are ordered by the share of scheduled reports received, then the reports due in the week (the longer record first), then the median arrival, then the longest silence.
The score is the weighted mean of its six parts, from the last 7 days. How a station is ranked sets out each part.
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 30 min, 48 in 24 hours. Two reports in the same 30 min count as one received.

Station report
Drawn from the register, in the manner of the Field Book, and opened beside the plates that explain each part of it.
At 1,140 ft above sea level, 4 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 28.71 inHg and the temperature at 54.9 F.

FB-ENG-003, Fig. CHydrostatic balanceWhy a barometer 1,140 ft up reads less: it weighs only the air above it.
On Oct 16 the noon sun stands 47 degrees above the horizon at 33.45 N, and the day is 11 h 11 min long. Level ground there takes 74 per cent of the noon sunlight a surface facing the sun would.
