Joe D'Aleo, the first director of meteorology at the Weather Channel who now works with WeatherBELL, is explaining to anyone who will listen that NOAA did exactly that.

Closing line:

"The NOAA, NASA and the Hadley Center press releases should be ignored. The reason which is expanded on with case studies in the full report is that the surface based data sets have become seriously flawed and can no longer be trusted for climate trend or model forecast assessment in decision making by congress or the EPA."

AFAIK this is based on raw, original weather station data.
