Urban Heat Island Studies – Do Pristine Weather Stations Even Exist?

This article tests the hypothesis:
Measured historical factors can be used to distinguish between urban and pristine stations.
Australian weather stations and data were tested. Australia’s low population density plus its many weather stations allow many “pristine” station candidates to be examined for studies of Urban Heat Island (UHI) effects.
From an initial list of 1,000+ stations, those with adequate data were narrowed down subjectively to 45 pristine station candidates. Some of their general properties are tabled below.

If several stations in a set are truly pristine, they should have similar temperature trends over time. If they do not have similar time series trends, then some factor more than natural variation must be affecting them; they cannot all be pristine.
Here is a graph of the trends of the 45 candidate stations.
