Station report

Lafayette 13 SE, in 5 sheets

Drawn from its report of Oct 16, 2026, 8:00 AM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.

1The air

Contents

67.5 F with a dew point of 66.6 F, 97 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 200 ft up.

From the Field Book

FB-WAT-020, Fig. AFog types
The temperature within 0.9 F of the dew point: the air is close to fog.
FB-WAT-002, Fig. CHumidity variables
The same lift, worked for another air: how the humidity climbs as the air rises and cools.
FB-ENG-011, Fig. AWater vapour as a gas
How much vapour air can hold at each temperature, which sets the dew point.
FB-ENG-005, Fig. ALapse rates and stability
The dry rate the lifted air cools at, against the air around it.

2The wind

Contents

At 2 mph: force 1, a light air on the Beaufort scale.

From the Field Book

FB-EVT-150, Fig. AHigh wind
How 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 geometry
Why large scale winds turn, and blow round a low rather than into it.

3The column

Contents

At 35 ft above sea level, 0 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 29.88 inHg and the temperature at 58.9 F; it reports 67.5 F, 8.6 F warmer than standard.

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 35 ft up reads less: it weighs only the air above it.

4The sun

Contents

On Oct 16 the noon sun stands 51 degrees above the horizon at 30.09 N, and the day is 11 h 17 min long. Level ground there takes 78 per cent of the noon sunlight a surface facing the sun would.

From the Field Book

FB-ENG-007, Fig. ARadiation budget
Where the sunlight that reaches this ground goes once it arrives.

5The instrument

Contents

A weather instrument, 35 ft above sea level. Its report of Oct 16, 2026, 8:00 AM local time is written on the sensors that made it.

From the Field Book

FB-INS-001, Fig. AWhat an instrument is
A surface station taken apart: what each of these sensors is.
