mimillman Posted February 27 Share Posted February 27 I didn’t realize the scale of the streak in the 1870s and 1880s. Is measurement error a possible blame there? Link to comment Share on other sites More sharing options...

Is measurement error a possible blame there? The official station for Chicago has moved around a lot. At the time, it was downtown and near the lakeshore, with a rooftop exposure. You can see the locations here from the 1947 annual climate data publication. You can see the thermometers were situated 70-75 feet above ground in the 1870s and 1880s, and then from 140 to 240 feet above ground until the move to the university. Looks like they were properly sited 7 feet about the ground there. Probably exaggerates the urban heat island effect since rooftop measurements tend to run warmer than ground temperatures. The downtown station at the Courthouse anyways did tend to run about 2-2.5F warmer than Midway Airport during the winter, and a degree or so warmer than the University of Chicago site. The yearly means at Midway and University of Chicago were similar, with downtown about 1-1.5F warmer. 2 Link to comment Share on other sites More sharing options...
TheClimateChanger Posted February 27 Share Posted February 27 And before @michsnowfreak chimes in, I'm not saying those weren't mild winters. From the data I've seen they were all warm winters. That period had some weird ups and downs with some colder winters interspersed with very mild winters, but clearly with 5 of the top 6 [prior to this season] from that era, it's being affected by the location and exposure of the observing station.

DocATL Posted February 27 Share Posted February 27 Will be interesting to see if Chicago beats the record high today followed by a 50° tumble. Curious what’s the biggest temperature change in a 24 hour period? I assume that record is safe.. Link to comment Share on other sites More sharing options...
