What the hell is supposed to happen here? Oh yeah - there is no )'supposed', I can make it up. So I have :-)...
So with a somewhat cynical shrug, I added the nuclear option - to match every WMO possible, and turn the rest into new stations (er, CLIMAT excepted). In other words, what CRU usually do. It will allow bad databases to pass unnoticed, and good databases to become bad, but I really don't think people care enough to fix 'em, and it's the main reason the project is nearly a year late.

Apply a VERY ARTIFICAL correction for decline!!

IMPORTANT NOTE: The data after 1960 should not be used. The tree-ring density' records tend to show a decline after 1960 relative to the summer temperature in many high-latitude locations. In this data set this "decline" has been artificially removed in an ad-hoc way, and this means that data after 1960 no longer represent tree-ring density variations, but have been modified to look more like the observed temperatures.
