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 131 ft above sea level, 0 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.78 inHg and the temperature at 58.5 F.
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 131 ft up reads less: it weighs only the air above it.
On Oct 16 the noon sun stands 63 degrees above the horizon at 18.08 N, and the day is 11 h 36 min long. Level ground there takes 89 per cent of the noon sunlight a surface facing the sun would.
