...before Anthony Watts starts analysing his data from Surface Stations.
He's got 819 done now (67% of network), and will begin work when he hits 916 or 75% of the total. Not that we don't know what an honest assessment of the station data will reveal. An analysis has already been done on the 1st 1/4 or so of the stations back in 2007, and it basically validated the GISSTEMP data. Its significant that Steve McIntyre seems to have given up on the project:
surfacestations.org has made a concerted effort to identify high-quality stations within the USHCN network (CRN1-2 stations) and preliminary indications are that the GISS U.S. estimate will not differ greatly from results from the "best" stations (though there will probably be a little bias.)
