Station report

Toolik Lake 5 ENE, in 5 sheets

Drawn from its report of Oct 16, 2026, 1:00 AM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.

1The air

Contents

-0.0 F with a dew point of -0.1 F, 100 per cent relative humidity. The air is saturated at the ground.

From the Field Book

FB-WAT-020, Fig. AFog types
The temperature within 0.0 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 3 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 2,625 ft above sea level, 9 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 27.19 inHg and the temperature at 49.6 F; it reports -0.0 F, 49.7 F colder 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 2,625 ft up reads less: it weighs only the air above it.

4The sun

Contents

On Oct 16 the noon sun stands 12 degrees above the horizon at 68.64 N, and the day is 8 h 46 min long. Level ground there takes 21 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, 2,625 ft above sea level. Its report of Oct 16, 2026, 1:00 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.
