[ExI] Living temperature dataset

GISS “raw” station data – before and after

Look at the comparison before and after.
Data is truncated before 1900 and temp are adjusted down for the first 
part of the century and up for the latter

Could be of interest how, the raw datasets continue to be "living" 
documents, as they continue to change and are continuously "improved" to 
show the raising temperatures to the unwashed masses.

Commenter  Peter Hartley (17:41:16) :
<<I think it is interesting that many of the adjustments are relatively 
small after 1979. Perhaps the availability of satellite temperatures 
from then on has “discouraged” further large adjustments over this 
period. Increasingly, it is looking like ever larger adjustments 
downwards are being made to earlier temperatures to maintain the 
appearance of rising temperatures over the long term. Correspondence 
with the satellite temperatures from 1979 is then used to justify the 
whole series including its cooled earlier temperatures.>>

Do they at the LHC "improve" the data in the same way?
