Said raw data are still available you know. The station logs they got them from are still there. All you have to do is go and ask for them again.

Of course the reason CRU 'lost' these data, was because they originally concluded that they weren't good enough to use and then a few years later someone decided to free up some storage space by getting rid of copies of unused data from their archive.

Q: Can we see the data?
A: No, we deleted some of it after concluding that it wasn't good enough to use. You can go to the station logs and get it if you want. Knock yourself out.

Q: Can we see the algorithms?
A: Sure. They are in the methods section of the dozens of papers published in the peer reviewed literature dealing with this area. We have links to these papers on our website.

If you want the "raw" numbers don't ask the CRU, ask the people who gave the numbers to the CRU. The CRU may have destroyed their copies of some of the data, but since they aren't the source of the data who cares?
