Observations
Cooler in shade.
By how much?
The largest sun–shade difference appeared at midday. Compare the observed series, then read what the sample can and cannot tell us.

A day, in three readings.
Illustrative mean air temperature by observation window, averaged across six paired routes and three field days.
All three series shown. Exact values are in the table below.
The midday difference was 2.4°C. It narrowed again by late afternoon.
The pattern is consistent with a shade association. It does not establish that canopy alone produced the difference.

Behind the lines
The values,
in plain sight.
Means in °C. The paired difference is open sky minus shade. These are fictional summary observations.
| Time | Shade | Open sky | Reference | Difference |
|---|---|---|---|---|
| 10:00 | 20.8 | 22.0 | 21.6 | 1.2 |
| 13:00 | 24.6 | 27.0 | 25.7 | 2.4 |
| 16:00 | 23.1 | 24.7 | 24.0 | 1.6 |
Read the uncertainty
A result with
edges around it.
Only three clear days were sampled. Routes were selected for practical access, not randomly. Building shade, wind and surface materials varied between points.
Repeated readings improve the description of these routes. They do not enlarge the number of independent locations.
