Revisiting the surface stations;
A new study published in the ISPRS Journal of Photogrammetry and Remote Sensing presents clear-sky surface UHI (SUHI) intensities for 497 urbanized areas in the United States by combining remotely-sensed data products with multiple US census-defined urban areas.
The SUHI intensity is the difference in surface temperature between the built-up and non-built up pixels of an urbanized area.
The study reported that the daytime summer SUHI was 1.91 °C higher and the daytime winter SUHI was 0.87 °C higher.
Now if only reality played a part in any discussions.
And it’s not just the siting/land use. There’s completely new technology in many of these stations that measures temperatures with much smaller temporal resolution–instead of, for example, hourly observations, it’s effectively real-time, so a short-duration spike in temps (which one typically sees with influences such as reflections, vehicle emissions, etc.) will ‘register’ as the official high temperature. We didn’t have this ability 100 years ago. There are so many reasons that the long-term temperature record is nearly garbage, but the public has been brainwashed to ‘trust science’. Maddening.
Indeed. Classic Apples vs Oranges comparison situation. The comparative data tell us very little, if anything about the trend.
now some needs to shove this data up algoreBULLshit’s rectum, till it comes out of his left nostril
the other issue, is that the nighttime lows are likely higher as well as the absorbed heat in the concrete and asphalt bleeds off
Speaking of concrete.

The average global climate variations according to records are about 2 degrees C above and 2 degrees C below
the baseline for the last 100 years. Or as we American say about 8 degrees peak to peak. The long-discredited
hockey stick graph should look like a flat line with wiggles but no business end. Michael Mann got away with
his fraud because his spreadsheet auto-scaled and he exaggerated the hell out of the last 50 years shown
in the graph!
