Page "Stephen McIntyre" Paragraph 13

My original interest in GISS adjustment procedures was not an abstract interest, but a specific interest in whether GISS adjustment procedures were equal to the challenge of " fixing " bad data.

If one views the above assessment as a type of limited software audit ( limited by lack of access to source code and operating manuals ), one can say firmly that the GISS software had not only failed to pick up and correct fictitious steps of up to 1 deg C, but that GISS actually introduced this error in the course of their programming.

According to any reasonable audit standards, one would conclude that the GISS software had failed this particular test.

While GISS can ( and has ) patched the particular error that I reported to them, their patching hardly proves the merit of the GISS ( and USHCN ) adjustment procedures.

These need to be carefully examined.
