re: #240 AJStrata
NCDC here admits there is only one study that has attempted to measure the quality of the US network. Moreover it only sampled a small number, and was performed by NOAA (who clearly have a conflict of interest here).
Conflict of interest? How about actually looking at the data instead. Look at a direct comparison between over 1200 stations in the USHCN system and the cherry picked 70 “best” stations from surfacestations.org: [Here] Big difference? I don’t think so. Unless you’d like to say that the entire surface record is completely bogus.
