From the Field Book

FB-ENG-001, Fig. AAtmosphere in section
The whole standard atmosphere this station stands in, from the ground to the edge of space.
FB-ENG-003, Fig. CHydrostatic balance
Why a barometer 20 ft up reads less: it weighs only the air above it.

2The sun

Contents

On Oct 16 the noon sun stands 24 degrees above the horizon at 57.16 N, and the day is 10 h 04 min long. Level ground there takes 40 per cent of the noon sunlight a surface facing the sun would.
