Station report
Mauna Loa 5 NNE, in 5 sheets
Drawn from its report of Oct 15, 2026, 3:00 PM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
49.6 F with a dew point of 41.7 F, 74 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 1,800 ft up.
At 11,179 ft above sea level, 34 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 19.65 inHg and the temperature at 19.1 F; it reports 49.6 F, 30.5 F warmer than standard.
On Oct 16 the noon sun stands 61 degrees above the horizon at 19.53 N, and the day is 11 h 34 min long. Level ground there takes 88 per cent of the noon sunlight a surface facing the sun would.
