This kind of thing is as fascinating as a soap opera, but I want to know how it comes out. Near the bottom of the file, I find:
I am seriously close to giving up, again. The history of this is so complex that I can’t get far enough into it before by head hurts and I have to stop. Each parameter has a tortuous history of manual and semi-automated interventions that I simply cannot just go back to early versions and run the update prog. I could be throwing away all kinds of corrections – to lat/lons, to WMOs (yes!), and more.
The file peters out, no conclusions. I hope they find this poor guy, and he didn’t hang himself in his rooms or something, because this file is a summary of three years of trying to get this data working. Unsuccessfully.
I think there’s a good reason the CRU didn’t want to give their data to people trying to replicate their work.
It’s in such a mess that they can’t replicate their own results.
