Over at Steven Goddard’s blog he is trying to point out how much USHCN data is “Estimated”.

From the readme.txt file: " 'E' indicates the data value is an estimate from surrounding values; no original value is available;"

So I had a copy of the data from last month because of a previous post.

So I thought … take the Final data and graph each month comparing data with an E flag to all the data without an E flag.

Surprise. Estimated data is Warming Data. And that is ignoring all the manipulation in going from Raw to Final data.
