Tornetrask, 1500 year reconstruction.

MXD data from Tornetra¨sk were first published by
Schweingruber et al. (1988). This original data set of 65
individual tree-series covered the time period AD 441–1980
and is hereafter denoted SEAL80 [WSL (Dendro Database,
WSL, Switzerland. http://www.wsl.ch/dendro/dendrodb.
html). Here, the MXD data is updated to AD 2004 using
new samples from 35 relatively young trees. Thus, the new
Tornetra¨sk MXD data-base includes samples from a total
of 100 trees and covers the period AD 441–2004. Dry dead
wood covers the period AD 441–1789 and living trees cover
the period AD 1336–2004.

Re-reading it is clear that the old data set is apparantly available in some form but the new data is not. Is that the issue or is the old data in a processed rather than “raw” format?

Thanks for the Grudd article, which is very provocative. Perhaps this would be a good time to renew your request? If he’s unresponsive, Lars Berg at #8 has offered to help obtain same, under Sweden’s “open-access” law.

Incidentally, in private corresp with a UTor climatologist, he mentioned frustration in trying to get an “equable climate” article published, remarking “equable climate is a dangerous topic!” And he’s a card-carrying AGW guy….

Keep up the good work!

It also appears that Grudd’s data is accessible to all

That’s news to me. I don’t know where it is nor did I see any data bank identified in the article. The new data is not at the WDCp/ITRDB. Perhaps it’s in the password protected top-secret Euro tree ring data base, but Briffa has refused to give me access to this site. I emailed Grudd some time ago asking him for a digitial version of his recon, but got no answer. You may be thinking of the “Open Access” disclaimer on the article – but that’s the article not the data.

Also many tree ring researchers have very commendable practices about archiving data – the ITRDB data set is very large. The problem is that many key researchers don’t archive data in a timely data, as discussed at length on many threads.
