Section 7.1 Responses

7. The keeping of accurate records of datasets, algorithms and software used in the analysis of climate data.  A key concern expressed by a number of correspondents and commentators has been as to whether datasets, and analyses based thereon, were deleted. 

QUESTIONS TO ADDRESS

 1 Were formal „data dictionaries‟ kept of the data sets acquired by the CRU at various times from other bodies such as the UK Meteorological Office Hadley Centre and its equivalents around the World?

2  Were comprehensive records kept of the way these various data sets were used, the statistical and other algorithms used in processing them, and the various software programmes and modules used to carry out that processing?

3.  Does a formal library of algorithms and software used by the CRU exist?

4.  What quality control measures were used to test the various algorithms and software modules developed by the CRU?

5. What techniques did members of the CRU employ to ensure the integrity of the various applications used to process climate data?

6.  What policies are in place to ensure the formal archiving of data sets and resultant analyses for future use and review.

    Digitization of the hard copies of “station histories” was prepared in
    1989-90 by Ms. Zhao-Mei Zeng (IAP/CAS) only for the 60-station network, while the “station histories” of other stations, including those we used in 1990 urban warming study, were available in paper form, as I have already
    indicated in my 4/30/07 e-mail to you. Therefore, the use of the word
    “fabrication” in your document is totally absurd.
    Concerning the current status of these hard copies of “station histories”,
    Ms. Zeng told me when I was in Beijing in April 2007, that she no longer has the access to these information because it has been a long time (since 1990) and also IAP has moved office. But if you are interested, you can make an
    inquiry to the China Meteorological Administration using the web site:
    [4]http://211.147.16.25/ywwz/about/cma.php.
    I believe that I have made it very clear what we had done with regard to the
    “station histories” in 1990 urban warming study. What and how you are going to proceed from now on is entirely your decision.

    Dear Dr. Wang,
    >>
    >> Regarding the Chinese meteorological data analyzed by Wang et al.
    >> [GRL, 1990] and Jones et al. [Nature, 1990], it now seems clear that
    >> there are severe problems. In particular, the data was obtained
    >> from 84 meteorological stations that can be classified as follows.
    >> 49 have no histories
    >> 08 have inconsistent histories
    >> 18 have substantial relocations
    >> 02 have single-year relocations
    >> 07 have no relocations
    >> Furthermore, some of the relocations are very distant–over 20 km.

    Ya can’t make this stuff up….! My take on it is that the data that Phil ‘lost’ has been obtained through inter-library loan.

    clued me into looking at Warwick Hughes’ latest

    February 20th, 2010 by Warwick Hughes

    It has finally happened, many thanks to a volunteer in California who through the inter-library loan system found a copy of the Martin Marietta 1991 edition DoE book published by CDIAC – and has scanned the entire book.

    The Jones et al Northern Hemisphere TR022 book with station documentation details, including corrections is now available as four pdf files. The much shorter TR027 Southern Hemisphere book has been online in html form for several weeks.

    I like this one:

    Here’s SH (of course, Wigley is all in these)

    This is a good place to look:
    Ongoing review of 1986 Jones et al papers compiling global temperature trends that now define “IPCC global warming”. By Warwick Hughes and other hard working contributors who can choose to remain anonymous.
