The two “lost” Graumlich foxtail series used in Esper et al 2002 were archived today at WDCP. Only the specific series that I had requested were archived; other series in Bunn et al 2005 were not archived – see prior discussion here. UPDATE May 17: Graumlich also archived two chronologies (Boreal -ca636.crn; Upper Wright – […]
An interesting comment on Hegerl et al by James Annan here.
One more attempt to extract data. This the 39th email in my correspondence with Science and I still don’t have a complete record on either Esper et al 2002 or Osborn and Briffa 2006. And people wonder why I haven’t published more. Continues from here Dear Dr Hanson, Thank you for your continued efforts in […]
Getting methodological information from Esper is a bit like dealing with Mann, a lot like dealing with Mann. It really makes me wonder whether there might be some clunker like Mann’s PC methodology lurking in Esper’s closet. Like Mann, instead of providing a comprehensive methodological desscription ideally with code as in econometrics journals, Esper would […]
There is something weird going with Esper’s delivery of data, where he delivered quite a lot of material – but left out some key data. Here ‘s the status on data – there are some puzzling methodological issues which I’l’l return to. Chronologies: Esper sent 13 of 14 chronologies in February. This was very interesting […]
Osborn and Briffa site chronologies differed from Esper site chronologies for 4 sites. Site chronologies can differ depending on the standardization method used; in order to analyze the effect, one needs to see the measurement data. Hundreds of measurement data sets have been archived at WDCP. The really weird thing is that the Hockey Team […]
I’m up to 38 emails back and forth with Science now in trying to get data. A little more drifted in April, about which I’ll report on in a couple of posts. My most recent progress report was here One of the questions pertained to a discrepancy between the correlation between gridcell temperatures and foxtail […]
I’m working on a long note, but probably a short interim note will make some sense. From the point of view of simply advancing our particular take on the MBH98 mess, as between Wahl et al and von Storch et al, there are pros and cons to us for either side being right. So I’d […]
Several people have written to me about today’s article in Nature by Treydte et al (including Esper) announcing that the 20th century is the wettest period in the millennium. Treydte et al state: Comparison with other long-term precipitation reconstructions indicates a large-scale intensification of the hydrological cycle coincident with the onset of industrialization and global […]
It’s obviously been pulling teeth to get data from Esper. After only two years of trying, I’ve recently obtained all but one site chronology and 10 of 14 measurement sets; and gobbledy-gook about methodology. It’s a very Mannian process. While I continue to try to get the rest of the information, I thought that it […]
