Ray Sanders #418

Ray Sanders updates his Surface Stations project to classify all 385 UK Met Office weather stations using WMO siting classes, claiming 88% are class 3–5 and 112 meet no regulations, including many in walled or private gardens and car parks. He argues poor siting, degraded maintenance after automation, and rapid platinum resistance thermometers in Stevenson screens create spikes and non-comparable records versus older liquid-in-glass methods. He alleges rounding/conversion issues, data from non-existent “climate averages” sites, refusals under FOI, and deletion of queried webpages. He presents analyses of stable long-term records at Wye and effects from a solar farm at RAF Lyneham, and plans more reconstructions with helpers. 00:00 Project Update Intro 01:49 WMO Siting Classes Explained 03:23 Most Stations Fail Standards 05:54 Walled Gardens Hotspots 11:55 Car Parks and Heat Sources 13:58 Thermometers and Response Time 18:27 Stevenson Screen Meets PRT 20:36 Sampling Rates and Spikes 24:45 Fahrenheit to Celsius Rounding 28:00 Maintenance and Automation Decay 32:30 Phantom Stations and FOI Fight 37:59 Allies and Data Deletions 42:16 Searching for Good Stations 42:30 Best Station Locations 43:39 Wye Data Deep Dive 44:59 Anomalies And Baselines 46:36 Manual Records Reveal 1930s 50:00 Solar Farm Heat Jump 51:19 Dyce Vs Craibstone 55:06 Met Office Classification Errors 59:53 Questionable Data Practices 01:02:21 US Climate Reference Network 01:07:38 Why He Started The Crusade 01:13:53 Focus On Great Britain 01:14:51 Thanks And Wrap Up https://x.com/RaySand17710097 ========= Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summaries My Linktree: https://linktr.ee/tomanelson1
