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 20 min, 72 in 24 hours. Two reports in the same 20 min count as one received.

Station report
CD032, in 6 sheets
Drawn from its report of Oct 4, 2026, 1:51 AM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
2The air
Contents68.0 F with a dew point of 48.4 F, 49 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 4,500 ft up.
From the Field Book
FB-WAT-002, Fig. CHumidity variablesThe same lift, worked for another air: how the humidity climbs as the air rises and cools.
FB-ENG-011, Fig. AWater vapour as a gasHow much vapour air can hold at each temperature, which sets the dew point.
FB-ENG-005, Fig. ALapse rates and stabilityThe dry rate the lifted air cools at, against the air around it.
3The wind
ContentsFrom the north northeast (32 degrees) at 7 mph, gusting 7 mph: force 2, a light breeze on the Beaufort scale. The strongest gust today was 7 mph.
From the Field Book
FB-EVT-150, Fig. AHigh windHow a high wind reaches the ground, and the strengths a warning is issued at (40 mph sustained, 58 mph gusts).
FB-ENG-008, Fig. ACoriolis as geometryWhy large scale winds turn, and blow round a low rather than into it.
4The column
ContentsAt 29 ft above sea level, 0 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.89 inHg and the temperature at 58.9 F; it reports 68.0 F, 9.1 F warmer than standard.
From the Field Book
FB-ENG-001, Fig. AAtmosphere in sectionThe whole standard atmosphere this station stands in, from the ground to the edge of space.
FB-ENG-003, Fig. CHydrostatic balanceWhy a barometer 29 ft up reads less: it weighs only the air above it.
5The sun
ContentsOn Oct 4 the noon sun stands 47 degrees above the horizon at 38.56 N, and the day is 11 h 31 min long. Level ground there takes 73 per cent of the noon sunlight a surface facing the sun would.
From the Field Book
FB-ENG-007, Fig. ARadiation budgetWhere the sunlight that reaches this ground goes once it arrives.
6The instrument
ContentsA road weather station, 29 ft above sea level. Its report of Oct 4, 2026, 1:51 AM local time is written on the sensors that made it.
