I do not have a copy of the previous version but I am hoping Steve does so he can compare if anything has changed.

DC, those posts are #s 138 and 140 at the link below:

There was a legitimate concern raised about the existence of the “carryover” error in earler months, and there were even two concrete examples (Resolute and Finland). So I thought it was a relevant investigation. Actually, I was surprised to find only three definite errors, given that Steve had stumbled on one of them more or less by accident. But it still needs to be fixed.

I have no idea what the 2007 GHCN monthlies will reveal. I’ll have a look at it later today when I get a few minutes.

Your suggested links point back to this thread, so I can’t find them. Can you point me to the right thread? Thanks.

DC, I think the bigger picture intent of these audits at CA is to determine the general reliability that can be expected of these temperature data sets. I have compared UAH/RSS to GISS at the links below and I suspect that real differences exist. In order to make a more detailed analysis of these differences, I would judge it important to determine the QC/QA involved and willingness of the data set owners/keepers to reveal their methods and explain the errors detected in their data sets.

I may be wrong in my impression, but you seem more intent on busily showing that this particular error(s) was inconsequential to the overall picture.

PS. It appears to be the same version as the one that was deleted last week. Gridcell 329 is the same as before and is still problematic.
