Steve, unfortunately for this station the
raw data ends in 1984, so it's a bit hard to say much about a difference in slope between
raw and adjusted
data from 1970 - 1984 (I would have to do a significance testing to see if you even have enough
data records for any slope to be significant for only 15 years of
observations).

raw observations, length of record of
observations, and the analysis methods used to transform
raw data into reliable climate
data records by removing existing biases from the

Copernicus's contribution concerned the Earth
observation value chain: across two separate workshops audiences were able to see a progression from

Mr Jones: [«The most startling

As the trend in the US rural stations, which at least until very recently employed these min / max stations, has been from early evening
observation (5 pm or 7 pm in most of the sources I've found) to early morning
observation (usually 7 am), this has been presumed to put an artificial cooling bias into the temperature record, so a net positive, and increasing as more stations have been converted, correction has been added to the
raw data.
For a station, when the time of
observation is shifted from early evening to early morning, the number of «duplicate» minimum readings in the
raw data should increase greatly if there is no other resetting.
I went to the
raw source (http://www.cru.uea.ac.uk/cru/people/melvin/PhilTrans2008/YamalADring.
raw) but the format is a pain as it will involve lots of manipulation to put it into a format I can more easily use e.g.
observation [i] = -LCB- tree, year, width, age -RCB--- I didn't see age in the
raw data, is age just set as the first year for which there is a reading for the tree sample?

observation.
For example, changes in time of
observation, adjustment for a move of a station that was previously sited next to a heat source to a better location (that now allows the station to be classed as Class 1 or 2), switch to a different temperature measurement device or system, etcetera, could explain why smaller classes of
raw data don't track well with the overall trend calculated from homogenized station trend
data.
These surface networks have had so many changes over time that the number of stations that have been moved, had their time of
observation changed, had equipment changes, maintenance issues, or have been encroached upon by micro site biases and / or UHI using the
raw data for all stations on a national scale or even a global scale gives you a result that is no longer representative of the actual measurements, there is simply too much polluted
data.
