Ray Sanders #418

<p>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.</p><p><br></p><p>00:00 Project Update Intro</p><p>01:49 WMO Siting Classes Explained</p><p>03:23 Most Stations Fail Standards</p><p>05:54 Walled Gardens Hotspots</p><p>11:55 Car Parks and Heat Sources</p><p>13:58 Thermometers and Response Time</p><p>18:27 Stevenson Screen Meets PRT</p><p>20:36 Sampling Rates and Spikes</p><p>24:45 Fahrenheit to Celsius Rounding</p><p>28:00 Maintenance and Automation Decay</p><p>32:30 Phantom Stations and FOI Fight</p><p>37:59 Allies and Data Deletions</p><p>42:16 Searching for Good Stations</p><p>42:30 Best Station Locations</p><p>43:39 Wye Data Deep Dive</p><p>44:59 Anomalies And Baselines</p><p>46:36 Manual Records Reveal 1930s</p><p>50:00 Solar Farm Heat Jump</p><p>51:19 Dyce Vs Craibstone</p><p>55:06 Met Office Classification Errors</p><p>59:53 Questionable Data Practices</p><p>01:02:21 US Climate Reference Network</p><p>01:07:38 Why He Started The Crusade</p><p>01:13:53 Focus On Great Britain</p><p>01:14:51 Thanks And Wrap Up</p><p><br></p><p><a href="https://x.com/RaySand17710097">https://x.com/RaySand17710097</a></p><p>=========</p><p>Slides, summaries, references, and transcripts of my podcasts: <a href="https://tomn.substack.com/p/podcast-summaries">https://tomn.substack.com/p/podcast-summaries</a></p><p>My Linktree: <a href="https://linktr.ee/tomanelson1">https://linktr.ee/tomanelson1</a></p>
