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.
