Why is it that people like Zeke can’t understand what they are doing wrong?
Using anomalies, infilling and gridding might be OK if you were happy with your network of stations and were just trying to generate a spatially averaged temperature anomaly across the US.
But that isn’t what I am doing. I am trying to see how much adjusting is being done, and the only sensible way to do that is to average the final station temperature and subtract the average of the raw station temperatures. That gives you a precise measure of the average adjustment for a particular year.
In a network with a systematically changing composition (rural station loss etc.) the very last thing you want to do is smear the data together and generate infilled data for the missing stations. That is 100% guaranteed to give you incorrect results. Besides a multitude of other sins, they are turning rural stations into urban stations and making UHI worse.
Zeke says that they are done adjusting data, but nothing could be further from the truth – the adjustments are increasing exponentially.
The temperature record needs to be turned over to responsible adults in the private sector.
