The site’s been crashing a lot lately. I’ve had to reboot it almost daily. We’re still on an old WordPress version and need to upgrade. Now that John A’s retired, the site has been on autopilot and needs a little bit of piloting. I would appreciate it if one of the regular readers with computer […]
Relatively up-to-date radiosonde data is available from the Hadley Center, tropical (20N-20S) is here. Ratpac and Angell are not up to date. The tropical troposphere has been a source of disputes recently, but I haven’t seen any discussion of up-to-date radiosonde data, [Note: Luboš has a current discussion on radiosondes.) You will recall the diagram […]
I’ve been foraging through ICOADS SST data for the past week and have a number of posts in progress. Here’s a diagram that I’m planning to do several comments on. It shows information on the provenance of ICOADS data between 1850, the start of the HadCRU SST record, and the present. It is very obvious […]
Folland has been the leading IPCC authority on bucket adjustments. Folland et al 1993 carries out a comparison from early 1980s measurements of (presumably predominantly insulated) bucket and non-bucket measurements, arguing that the difference was about 0.08 (less than 0.12-0.18 suggested in 2006 by Kent and Kaplan. They reported a puzzling situation in the Gulf […]
Uninsulated Buckets A CA reader emailed me, observing that there may be relevant differences in insulated and uninsulated buckets in the post-World War 2 period, which could easily affect adjustment schedules. This makes a lot of sense to me and might reconcile a few puzzles and opening others. Let’s say that the delta between engine […]
After unveiling the Hadley Center adjustment error that has been used in all temperature compilations for the past 20 years, Phil Jones stated: Climate scientists should think about data quality more often, says Jones, so that there is no opportunity for incorrect data to sow seeds of doubt in people’s minds about the reality of […]
