Some, but not all, UK weather stations have records of soil temperature dating back over 100 years.

Some of the discontinuities (which can be of either sign) in weather records can be detected using jump point analyses (for instance in the new version of the NOAA product), others can be adjusted using known information (such as biases introduced because changes in the time of observations or moving a station).

In this case, they have the long records from the weather stations, and the relationship of the wider temperatures to those stations over the satellite period, and this is what you get when you put that together.

(BTW, you have to carry out special procedures to compensate for movement of weather stations in the anomoly record, which is why looking at raw data can be very misleading if the station has moved or procedures were changed.

Secondly, through the copious use of station weather data, a number of single station records with long term cooling trends are shown.

The mean temperature change or the OHC increase is an integral over all of that and therefore can be estimated to higher precision than any individual reading (just like for the weather station record).

My own analysis for my neck - of - the - woods (slightly less definite due to the data from the local weather station having stalled in May 2013 — probably due to spending cuts)-- February saw record rainfall, 38 % above the previous 55 - year February maximum and 3.35 sd above the February mean.

Combining the greater share of weather stations in more urban areas over time with this urban heat effect also tends to increase the rate that recorded temperatures tend to rise over time.

As a result of this extra urban warmth, if a weather station becomes urbanized, this introduces an artificial warming bias into the station's record, i.e., urbanization bias.
