Station charts
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.

Station report
Drawn from its report of undefined, in the manner of the Field Book, and opened beside the plates that explain each part of it.
From the east northeast (62 degrees) at 4 mph, gusting 9 mph: force 2, a light breeze on the Beaufort scale.
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.
At 773 ft above sea level, 3 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.09 inHg and the temperature at 56.2 F; the station's altimeter setting of 30.08 inHg means its barometer reads 29.25 inHg; it reports 71.0 F, 14.8 F warmer than standard.
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 773 ft up reads less: it weighs only the air above it.
On Oct 4 the noon sun stands 55 degrees above the horizon at 30.57 N, and the day is 11 h 38 min long. Level ground there takes 82 per cent of the noon sunlight a surface facing the sun would.
FB-ENG-007, Fig. ARadiation budgetWhere the sunlight that reaches this ground goes once it arrives.
A weather instrument, 773 ft above sea level. Its latest report is written on the sensors that made it.
