Another hockey stick. Coincident with the hockey stick of USHCN temperature adjustments, is a hockey stick of data fabrication. More than 40% of USHCN final station data is now generated from stations which have no thermometer data.
The graph below is generated by counting the number of reported monthly temperatures in the final and raw data sets. The have lost 30% of their station data since 1990, but still report adjusted temperatures for the missing data.
Final : ushcn.tavg.latest.FLs.52i.tar.gz
Raw : ushcn.tavg.latest.raw.tar.gz
Can you explain? That sounds pretty outrageous!
They have been rapidly losing stations, and fabricate data for the lost stations by interpolating from other stations.
It is my understanding that it’s not all just about “losing” stations, but even simply no longer collecting data from some stations that are not technically “lost”.
For example: in CA, they have stopped collecting from some stations in the Sierra Nevada, apparently preferring stations in the basins (San Joaquin valley, LA).
It has been reported that the geographic locations of the stations that are NOT being reported anymore, in comparison to those that are, is… interesting. But I do not have any hard figures at hand.
If I wanted to hide the decline, I’d hide the stations in the Sierra Nevada.
Here is a good graphic Anne. They are eliminating stations in higher latitudes, higher altitudes, and rural locations, in favor of warm biased stations. It ain’t ticket science.

iPhart alert! It ain’t ticket science, it’s ‘rocket science’ (not).
If you do not have any data to hand, Try Verity’s Diggingintheclay she has several post on the subject of The ‘Station drop out’ problem

(especially look at the older posts in this listing.)

One of his articles worth reading:
If you do not have inconvenient observational data, then just make stuff up!
Welcome to 21st century “science” …
I’d noticed that, doing some some comparisons between “raw” and adjusted temps, we often get adjusted temp records for dates where there is no corresponding “raw” record for that station; often for years at a time.
(BTW I put “raw” in scare quotes because it is anything but.)
At this rate, we’ll be over 100% by 2020. I’m not sure what happens then.
The Smoking Gun.
If you don’t have the data you want, hey just make it up.
nice.
No doubt most warmistas don’t have the scientific education to understand the implications.
You have remarked very interesting details! P.s. Nice web site =)
