On July 31, 2009, the purge of public data at CRU reached levels “unprecedented” in its recorded history. Climate Audit reader Super-Grover said that the data purge was “worse” than we expected.
On Monday, July 27, 2009, as reported in a prior thread, CRU deleted three files pertaining to station data from their public directory ftp://ftp.cru.uea.ac.uk/.
The next day, on July 28, Phil Jones deleted data from his public file – see screenshot with timestemp in post here, leaving online a variety of files from the 1990s as shown in the following screenshot taken on July 28, 2009.
The following day, the following listing of station data available since 1996 (discussed in my post CRU Then and Now) was deleted from public access: ftp://ftp.cru.uea.ac.uk/projects/advance10k/cruwlda2.zip, though other data in the file remained.
This is part of a broader lockdown at CRU. Ian Harris, Dave Lister, Kate Willett, Tim Osborn, Dimitrios, Clive Wilkinson and Colin Harpham all altered their FTP directories this morning. Only one directory (Tim Osborn -see below) has added material.
Revisiting the Advance 10K webpage this morning, all Advance 10K data was deleted from their FTP site. None of the Advance 10K data links at http://www.cru.uea.ac.uk/advance10k/climdata.htm work any more.
If you go to the directory page ftp://ftp.cru.uea.ac.uk/projects which formerly hosted ftp://ftp.cru.uea.ac.uk/projects/advance10k directory, it now contains only two directories between Sept 1999 and the present, both dated 8/1/2008, but containing data from 2001.
On July 31, 2009 at 10:41 am, Tim Osborn published a webpage entitled “controversy.htm”. It is located in a folder entitled ftp://www.cru.uea.ac.uk/people/timosborn/censored/ and the webpage ftp://www.cru.uea.ac.uk/people/timosborn/censored/controversy.htm itself is of course censored. [Update: Later on July 31, Tim Osborn, obviously a faithful Climate Audit reader, censored the censored folder and even the existence of the censored folder (and the controversy webpage) is now censored.]
I presume that the data has not been totally destroyed, only that, after many years of public availability, it has been put under lock and key. It’s as though CRU is having a collective temper tantrum.
