Chester County PA - Analytical Battle of Actual vs. Altered Climate Data

Your in denial mode. These two charts fit together well. The station moves at Coatesville and West Chester produce spurious cooling if they are left in the raw data. That's why NOAA matches raw data without station moves and you (COOP station avg) don't. You have Chester County as warm as the Philadelphia airport before the station moves. How silly is that.

@chubbs - this is all a bunch of subterfuge. In the vast majority of cases, NOAA systematically reduces the reported temperatures from the observed temperatures on a county-by-county basis, often in ways that make little logical sense. Chester County may very well be the only county in Pennsylvania where the opposite is true. So if there is a conspiracy, it's in the opposite direction as the one presupposed with this analysis.

Let's look at May 2025:

xMacis reveals three NOAA stations in Chester County, with a mean temperature of 61.5F. So it's true that the reported mean temperature is higher than the mean of these three stations. But the opposite is true in just about every other county in Pennsylvania.

And at the global level the net effect of all adjustments actually reduces the overall warming trend.
