KTKI (McKinney National, 9 mi) — a different place, not ground truth
This is a drift monitor, not an error report. A residual inside the shaded
±2°F microclimate band is expected yard-vs-airport
microclimate — do not tune inside this band. Only a persistent trend that walks
out of the band over weeks flags a real sensor change.
Residual Summary
Residual vs ±2°F band
How far the station sits from the airport baseline each day. Inside the shaded band is normal microclimate difference. Several days outside it means a real problem.
Are we slowly drifting?
30-day average gap vs the airport. Flat = stable; a steady climb or fall means a sensor is changing.
Residual vs Solar
If the dots tilt with sunlight, the model is still leaving a sun-related bias. A flat, shapeless cloud is what you want.
