Clear night, the shield read about a degree below the reference thermometer at dawn — radiative cooling again, not a calibration drift.
Anemometer cups cleaned, bearing still turns freely.

A single sensor mast on a garden shed, logging temperature, humidity and wind every ten minutes. Last reading was 2.5 °C with 1.3 m/s from the north. The page is updated by hand when I get round to it, so treat anything here as a rough record rather than a forecast.

Anemometer cups cleaned, bearing still turns freely.
Fog until mid-morning; humidity pinned at 99% for six hours and the sensor took a while to come back down afterwards.
Moved the shield about two metres away from the shed wall. The afternoon warm bias I'd been seeing since spring is mostly gone.
Replaced the battery in the outdoor transmitter; it had been dropping packets for about a week before I noticed the gaps.
