This is a video from 3 years ago where Tony Heller (Steve Goddard) presents a detailed analysis of the USHCN data set and how the data are diddled.
He also gets in a few “digs” at Hansen, Gore, and others over their outrageous and outrageously wrong predictions of doom in our time…
He has many graphs and some of them are remarkably simple and effective. Things like plotting the number or percentage of days over 100 F and 110 F for a given site. Pretty well shows where the hot years are, and they are around 1936 +/- not recently. 53 minutes.
There are two things in particular that make this video useful to me. First off, it says I don’t need to do all those things with USHCN (unless, of course, I wish to do it as a confirmation study). Second, I like the effect / impact of some of his graphs, so may use some of those ideas myself.
It’s always good to see what someone else has done to pick up ideas and avoid duplication without cause.

@EM: Tony’s GHCN climate grapher software is available for download. Its in the link box at the top of the site, called ‘UNHIDING THE DECLINE for Linux/Mac’ No separate action is required to get the data. Its contained in the software.
Yeah, some long time ago I tried to get it to run but there was some incompatibility with the system I was using then. Maybe time to try again.
FWIW, I’d rather just look at the output product to see what it does then dig through pages of code. I’ve done it, but… It is far far easier to say “Oh, look, a graph of temps over 100 F!” than to read over a few pages of code to find where it has something like “gcntm>100.0 then do” and figure out what and why… I like to reserve that for when I really need to know every single detail of the actions going on.
I have watched lots of Tony’s stuff recently (Tip from you?). I smile when I hear his ‘organised crime’ comments!
I found myself thinking that some random checks on his graphs are needed – it would be seen as a sort of peer review. It would lend cred to both parties if both had done totally independent analyses.
I thought Tony’s technique of looking at the number of days above X degrees was a good one because it lets him avoid having to use homogenized data.
@EM Would your unadjusted GHCN data make such a comparison possible / valid?
@Sandy McClintock:
It would to some extent. More importantly, I have the USHCN data also and after the “do over” is done for GHCN, I’m planning to load up the USHCN. At that point direct comparisons are possible.
Probably still a few months away from first load of data though. I’ve got some systems cleaning up to do first.
Has anyone else made his graphing S/W work? using Ubuntu 18.04 I had to comment out the load PIP command, but after getting that done it works. I’ve also added the later years to the CO2 table. IIRC it ended at 2014.
