Station report
Pierre 24S, in 5 sheets
Drawn from its report of Oct 16, 2026, 12:00 AM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
43.9 F with a dew point of 34.4 F, 69 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 2,200 ft up.
At 2,123 ft above sea level, 7 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 27.70 inHg and the temperature at 51.4 F; it reports 43.9 F, 7.5 F colder than standard.
On Oct 16 the noon sun stands 37 degrees above the horizon at 44.02 N, and the day is 10 h 49 min long. Level ground there takes 60 per cent of the noon sunlight a surface facing the sun would.
